| Q-6 | Dynamic Packet Filtering is used by .....? |
|---|
A | Firewalls | Explanation | Firewalls
Packet filtering firewall technology has been improved by the addition of dynamic packet filtering. In dynamic packet filtering all incoming packets are compared against defined rules contained in a limited command set for one or more low level protocols. The rules determine if the packet is denied or accepted and passed on to the network stack. Each packet is then associated with additional information based on information contained within the packet. Based on a combination of the data contained within the network packet and the state information, dynamic rules are added or removed from the packet filter. If a packet satisfies all of the packet filter rules it either propagates up the network stack for future processing or gets forwarded to the network host. |
| Q-7 | If you want to have secure communications on your Intranet, what must you implement in order to create your own key pairs? |
|---|
B | Certificate server | Explanation | Certificate server
In order to be able to accept credit cards on line, you must install a security certificate from the certificate authority. Verisign is a certificate authority. The certificates are used for data encryption and also for authenticating web sites. When you access a commercial web site and placing the order with your credit card, the Certificate, installed on that site, tells your browser that the web site is really who they say they are because they have been verified by the certificate authority prior to issuing the certificate.

| Q-10 | Which term means encrypted text? |
|---|
B | Ciphertext | Explanation | Ciphertext
Encryption (also called cryptography) is a method of transforming communications and stored data into a form that is unintelligible to anyone other than the intended receiver. The original data are referred to as plaintext and the encrypted data as ciphertext. With modern encryption systems, the data are represented as streams of 0's and 1's, and the encryption algorithm transforms the plaintext bit stream into one that appears random. |
| Q-11 | What protocol is the least secure?
|
|---|
A | SMTP | Explanation | SMTP
Simple Mail Transfer Protocol, a protocol used to transfer electronic mail between computers. The SMTP dialog usually happens in the background under the control of the message transport system, but it is possible to interact with an SMTP server using telnet to connect to the normal SMTP port, 25. |
| Q-12 | Encryption is used where?
|
|---|
A | In Virtual Private Networks | Explanation | In Virtual Private Networks
Virtual Private Networks are built using PPTP or other tunneling protocols to provide encrypted (secure) communications across the Internet. They are used for connecting two different company sites such as with an Extranet, or for allowing a remote user to securely access a site. |
| Q-13 | Which protocol has the highest security?
|
|---|
A | PPTP | Explanation | PPTP
Point to Point Tunneling Protocol, a protocol for connecting Windows NT clients and servers over Remote Access Services (RAS). PPTP can be used to create a Virtual Private Network between computers running NT. PPTP encrypts the data transmitted. |
| Q-14 | Where do the majority of security violations within corporate networks come from?
|
|---|
A | Employees | Explanation | Employees
Whether intentionally or unintentionally employees can usually cause the most havoc if their permissions are not properly controlled. |
| Q-15 | You want to increase the security of e-mail messages being sent from employees in your organization. Which of the following server types could you set up to help you to accomplish this?
|
|---|
C | Certificate | Explanation | Certificate
Establishing a certificate server using software such as Netscape Certificate Server or Microsoft Certificate Server would enable you to create and verify digital certificates that provide encryption of e-mail messages.
PGP (Pretty Good Privacy) can also be used to encrypt e-mail, however PGP is not a server type - it is software that can be used to encrypt e-mail using digital signatures as opposed to digital certificates.
Proxy servers can be used to cache web pages for faster access or to filter TCP packets. FTP servers can be used to transfer files. Neither of these servers encrypts e-mail messages.

| Q-16 | Susan's Web server crashes every time she restarts it. She uses a packet sniffer and discovers a ping flood directed at her server. Which type of attack is occurring?
|
|---|
D | Denial of service | Explanation | Denial of service
Denial-of-service attacks are the most common type of attack. These occur when the host or system cannot perform properly because another program or node on a network is using all the system's resources. A hacker can generate a rapid flood of information, such as a large number of ping packets (called a ping flood), to overburden or crash the network device.
A brute force attack occurs when a hacker attempts to gain access to the network as a legitimate user. The hacker keeps trying different combinations of user names and passwords until he is able to log on.
Spoofing refers to an attack in which the hacker's host or application poses as a legitimate network device. The hacker might use IP spoofing so it appears as though the packets originated from a trusted system.
An insider attack is one in which someone physically inside the organization does the hacking.
|
| Q-17 | What is the ability to change the IP packet to take the identify of another system called?
|
|---|
B | Spoofing | Explanation | Spoofing
Spoofing is using a protocol analyzer or other device to intercepting and decoding packets sent to and from the server in order to find the account ID and password. With this information the spoofer can pretend to be the transmitter or recipient of the data packet. |
| Q-18 | Which type of scan allows an antivirus program to find undefined viruses by looking for suspicious activity?
|
|---|
C | heuristic scan | Explanation | heuristic scan
A heuristic scan is a type of antivirus scan that looks for suspicious activity that might indicate a virus, even if there is no definition for that virus. Suspicious activity might be a program going resident, or making changes to the operating system. False alerts are common, and can scare an inexperienced user.
An on-demand scan is one that starts when the user tells the software to scan for viruses. It uses specific virus definitions.
An on-access scan looks for viruses whenever a file is accessed. For instance, when you open a file sent in an email, or download a file from the Internet, the software would automatically initiate a virus scan.
An emergency scan is performed when it is likely that a virus has already taken control of the computer. It runs from an emergency boot disk so that only the antivirus software and the operating system are running. |
| Q-19 | What single-key encryption method is used to encrypt and decrypt a message?
|
|---|
C | symmetric
| Explanation | symmetric
This is symmetric because the reciever decode a transmission with exactly the same key that was used to encode the transmission. |
| Q-20 | Which of the following describes a "man in the middle" security attack? |
|---|
A | A hacker intercepting and substituting a security key | Explanation | A hacker intercepting and substituting a security key
An Internet hacker may interfere with the initial public key exchange, by intercepting the very first message to a new correspondent and substituting the genuine public key with a bogus one. |
| Q-21 | You are the security expert on a Web site development team. The specification for an e-commerce system you are implementing requires secure user authentication. Which of the following solutions will meet those needs? |
|---|
B | Digital certificates | Explanation | Digital certificates
Digital certificates and certificate servers are a form of authentication and are used as a secure method of exchanging public keys over a nonsecure network such as the Internet. |
| Q-22 | You are getting a large number of ICMP (SMURF) attacks. How can you protect your network?
|
|---|
D | Filtering on the Proxy Server | Explanation | Filtering on the Proxy Server
Filtering on the proxy server is the way to protect your network from a smurf attack. Smurfing falls under the general category of Denial of Service attacks -- security attacks that don't try to steal information, but instead attempt to disable a computer or network.
Smurfing is a type of network security breach in which a network connected to the Internet is swamped with replies to ICMP echo (PING) requests. A smurf attacker sends PING requests to an Internet broadcast address. These are special addresses that broadcast all received messages to the hosts connected to the subnet. Each broadcast address can support up to 255 hosts, so a single PING request can be multiplied 255 times. The return address of the request itself is spoofed to be the address of the attacker's victim. All the hosts receiving the PING request reply to this victim's address instead of the real sender's address. A single attacker sending hundreds or thousands of these PING messages per second can fill the victim's T-1 (or even T-3) line with ping replies, bring the entire Internet service to its knees.
Smurfing falls under the general category of Denial of Service attacks -- security attacks that don't try to steal information, but instead attempt to disable a computer or network. |
| Q-23 | Why cannot U.S. sites support browser encryption that uses keys longer than 40 bits?
|
|---|
A | Most countries outside US only use browser capable of 40 bit encryption. | Explanation | Most countries outside US only use browser capable of 40 bit encryption.
Browsers prior to Netscape 4.7, and Internet Explorer 5.5, came in two flavors. Ones which have been exported from the US, which are limited to 40, and 56 bit support, due to US export regulations. These are called International or non-US versions. Browsers downloaded inside the US and Canada, support 128 bit 'strong encryption'.
In terms of what the numbers represent, "128" and "40" bit encryption refer to the size of the key used to encrypt the message. Roughly speaking, 128-bit encryption is 309,485,009,821,345,068,724,781,056 times stronger than 40-bit encryption. Presently, 40-bit encryption is not considered "strong" security in the cryptographic community. |
| Q-24 | Which are tunneling protocols? Choose 2 |
|---|
A | L2TP | Explanation | L2TP, PPTP
L2TP (Layer 2 Tunneling Protocol) and PPTP (Point to Point Tunneling Protocol) are used for creating Virtual Private Networks (VPNs) |
| Q-25 | Which protocol has the highest security? |
|---|
C | PPTP | Explanation | PPTP
Point to Point Tunneling Protocol (PPTP) is used to ensure that messages transmitted from one VPN node to another are secure.
The second best choice would be Layer Two Tunneling Protocol (L2TP) but L2TP alone cannot encrypt data. For encryption L2TP relies on IP security (IPSec). |
| Q-26 | You know that web pages using HTTP have a default "well known" port number of 80. But while accessing an Internet vendor you instead of seeing the URL http://www.examdrill.com/ you see that the URL is https://www.examdrill.com/ and there is a closed padlock in the status bar of the browser. What port number are you accessing? |
|---|
A | 443 | Explanation | 443
This is the default port for HTTPS/SSL. This is the encrypted form of HTTP that normally runs over port 80. This is the default port used when you do credit card transactions with an e-commerce site.
All communication between the server and the browser is encrypted when you use SSL. You can tell when you are using SSL by looking at the URL - it starts "https://" (as opposed to "http://") and most browsers have some visual indication, e.g., Netscape has an unbroken key or locked padlock in the bottom left-hand corner of the browser (on the Status Bar), Internet Explorer has a padlock that is locked toward the bottom right-hand corner of the browser (also on the Status Bar). SSL uses well known port number 443 |
| Q-27 | You are making an online purchase and notice that there is a padlock icon in the status bar of your browser window as shown below. What does this mean? |
|---|
A | You have contacted a server using Secure Sockets Layer Encryption. | Explanation | You have contacted a server using Secure Sockets Layer Encryption.
SSL is an encryption scheme. All communication between the server and the browser (for instance credit card number) is encrypted when you use SSL. You can tell when you are using SSL by looking at the URL - it starts "https://" (as opposed to "http://") and most browsers have some visual indication, e.g., Netscape has an unbroken key or locked padlock in the bottom left-hand corner of the browser (on the Status Bar), Internet Explorer has a padlock that is locked toward the bottom right-hand corner of the browser (also on the Status Bar). The absence of the padlock indicates that the data you are viewing is not secure. |
| Q-28 | Which technology implements VPNs using IPSec? |
|---|
A | L2TP | Explanation | L2TP (Layer 2 Tunneling Protocol)
Virtual Private Networks are built using PPTP or other tunneling protocols to provide encrypted (secure) communications across the Internet. They are used for connecting two different company sites such as with an Extranet, or for allowing a remote user to securely access a site. Of the two tunneling protocols which are important for the I-Net+ exam you should know that PPTP encrypts and tunnels data but L2TP uses IP Security protocol (IPSec) to encrypt data.. |
| Q-29 | Which step is most subject to network congestion? |
|---|
C | Transmitting the response from server to client | Explanation | Transmitting the response from server to client.
A server generating contents for the output and displaying the content on the client are not really bandwidth issues. They have to do with processing and display power in the server and the client. However getting a request to the computer and transmitting the response to the client are bandwidth bottleneck problems.
|
| Q-30 | What two things does a digital signature verify? |
|---|
A | Verifies the identity of the sender. | B | Verifies the information in a document was not tampered with. | C | Encrypts a message to which it is applied | D | Cannot stand up in court. | Ans | AB | Explanation | Verifies the identity of the sender.
Verifies the information in a document was not tampered with.
A digital signature verifies two things: the source of a document, and its integrity. When, for instance, a notary electronically signs a transcript, the entire document is mathematically manipulated to produce a fingerprint, which is then encrypted along with a unique ID. When the recipient checks the signature, it will fail to verify if even a single character has been changed. This assures that your copy of the document has not been tampered with, and that it came from the notary it purports to come from.
The simplest way to sign documents electronically is to use systems like PGP (Pretty Good Privacy) or VeriSign, which have gained widespread acceptance as secure signature systems, and have no per-use cost.
|
| Q-31 | What protocol does not use Logon Authentication? |
|---|
A | SLIP | Explanation | SLIP
Serial Line Internet Protocol (SLIP) does not provide error detection, compression or encryption.
Point-to Point Protocol (PPP) is the Internet standard for transmitting network layer datagrams, for instance IP packets, over serial point-to-point links.
Point to Point Tunneling Protocol (PPTP) is a protocol that can be used to create a Virtual Private Network between computers running NT.
Layer Two Tunneling Protocol (L2TP) is a tunneling protocol that operates at the data link layer of the OSI model L2TP uses IPSec to encrypt data. |
| Q-32 | If the server has lots of open connections but is not completing them You run "netstat -n -p tcp" and get the results as shown in the exhibit. What is happening? |
|---|
A | SNY attack | Explanation | SYN Attack
An intruder can write a program that will establish a connection with your server and half-open TCP ports. That will block the access to your server.If a large number of connections are in the SYN_RECEIVED state, it is possible that the system is under attack. Netstat can be used to identify how many half open connections you have.
|
| Q-33 | Which is a single key encryption method? |
|---|
B | Symmetric | Explanation | Symmetric
Symmetric encryption is a type of encryption where the same key is used to encrypt and decrypt the message. Asymmetric, or public key, encryption uses one key to encrypt and another to decrypt the message. |
| Q-34 | Why cannot U.S. sites support browser encryption that uses keys longer than 40-bits? |
|---|
A | Such technology is regarded as munitions grade by the U.S. government | Explanation | Such technology is regarded as munitions grade by the U.S. government.
The U.S. government has designated strong encryption technology, (such as 128 bits) as munitions and a threat to national security. It is illegal to export encryption technology based on more than 40 bits. |
| Q-35 | Access control is NOT used on which type of network? |
|---|
B | Internet | Explanation | Internet
While ISPs generally use access controls, the Internet itself is open to everyone that can obtain a connection. |
| Q-36 | Some of your user connecting via RAS, what's best to prevent unauthorized access to your network? |
|---|
D | Firewall | Explanation | Firewall
Firewalls are used to prevent unauthorized access from the external network such as Internet to your local network. Many organizations configure firewalls to prohibit access to certain domains. |
| Q-37 | Where could you find specifications for secure online transaction? |
|---|
C | SET | Explanation | SET
The SET Secure Electronic Transaction protocol is designed to help break down barriers to electronic commerce such as misuse or theft of data. SET was jointly developed by MasterCard, VISA, IBM and other technology companies. It's an industry-wide open standard for online credit card transactions.
SET helps ensure the privacy and integrity of real time credit card payments transactions over the Internet. The SET protocol only addresses the transaction payment phase -- from the individual, to the merchant, to the the merchant's current credit card processor. |
| Q-38 | In order to access a web site named secure.website.com that uses SSL and requires you to log on. Which URL is correct? |
|---|
D | https://username:password@secure.website.com | Explanation | https://username:password@secure.website.com
Web pages that require an SSL connection start with https. Notice the "s" after the "http.
Username and password are separated by a colon and Password and server are separated by an ampersand (@). |
| Q-39 | You just got over a denial of service due to a PING attack, what can you do to prevent it from happening again?
|
|---|
A | Reconfigure your firewall to disallow ICMP echo replies entering your network. | Explanation | Reconfigure your firewall to disallow ICMP echo replies entering your network.
A PING flood is when multiple ICMP PING messages are sent to the server. This will result in high traffic to your server and access to legitimate clients will be denied. By reconfiguring the firewall to disallow ICMP echo replies this kind of attack will be impossible. |
| Q-40 | Which of the following attributes can you use to increase the amount of space in between cells?
|
|---|
C | CELLSPACING | Explanation | The CELLSPACING attribute of the [TABLE] tag adds space in between cells. You specify the amount of space in pixels as in this example: [TABLE CELLSPACING="5"].
The CELLAPDDING attribute of the [TABLE] tag adds space in between the cell contents and the cell border. Its syntax is similar to that of CELLSPACING.
The BORDER attribute specifies the size of the border around the table. Its syntax is similar to that of CELLSPACING.
The COLSPAN attribute allows you to create cells that are wiser than other cells in the same column by allowing them to span multiple columns. You can use the COLSPAN attribute and the similar ROWSPAN attribute with the [TH] and [TD] tags.
|
| Q-41 | You want to create a bulleted list of three items on your HTML page. Which of the following code selections will enable you to accomplish this?
|
|---|
C | [UL][LI]Item1[LI]Item2[LI]Item3[/UL] | Explanation | [UL][LI]Item1[LI]Item2[LI]Item3[/UL]
Use [UL] to create an unordered, bulleted list. Use [OL] to create an ordered, numbered list.
Enclosed within the beginning and ending tags for an ordered or unordered list, use the [LI] tag before each item in the list. Closing [/LI] tags are unnecessary. |
| Q-42 | In a multi-tiered architecture object, request brokers can be implemented through what?
|
|---|
A | CORBA | Explanation | CORBA
If your application is running on a single computer, it has a one-tier architecture. If your application is running on two computers, for instance, a Web CGI application that runs on a Web browser and a Web server, then it has two tiers. In a two-tier system, you have a client program and a server program.
A three-tier application adds a third program to this, usually a database, in which the server stores its data. The flow of information is: a request comes from the client to the server; the server requests or stores data in the database; the database returns information to the server; the server returns information back to the client. Many technologies exist that help contain this complexity, including CORBA, EJB, DCOM, and RMI, and products based on these technologies are being marketed. |
| Q-43 | Which is a server side script?
|
|---|
B | PERL | Explanation | PERL
Two most popular types of server side scripts standards are CGI ( Common Gateway Interface)
and ISAPI (Internet Server Application Programming Interface). CGI scripts can be written in
many programming languages. PERL (Practical Extraction and Report Language) and C are
probably the most popular for writing CGI scripts. |
| Q-44 | HTML is an anagram for Hypertext Markup Language. The "D" in "DHTML" stands for what? |
|---|
A | Dynamic | Explanation | Dynamic
The purpose of Dynamic HTML is to make Web content more compelling, productive and interactive.
Microsoft and Netscape agree on some basic Dynamic HTML specifications, including address layering, which allows the overlaying of HTML text and images; positioning, which lets Web designers position information on a screen with pixel-level accuracy; and Web fonts.
|
| Q-45 | You have a graphic on your web page that is 40mm x 60mm. Which format loads the fastest?
|
|---|
A | 72 dpi | Explanation | 72 dpi
The lowest resolution would represent the least amount of data that must be transmittted. Therefore the graphic with a resolution of 72 dots per inch (dpi) would be transmitted more quickly than the other choices. |
| Q-46 | What is CSS?
|
|---|
A | Cascading Style sheet | Explanation | Cascading Style Sheet
CSS (Cascading Style Sheet) is a collection of [style] elements that describe how different HTML elements are presented. CSS information can be stored in a separate file on the server and all web pages can have links to that file. This way all pages will have the same look and feel. |
| Q-47 | You have created a Web page that uses some proprietary tags developed by Microsoft for Internet Explorer 5. What will happen when users view this page with browsers developed by other manufacturers? |
|---|
B | Text and graphics using the proprietary tags will not display as expected in some or all of the other browsers. | Explanation | Text and graphics using the proprietary tags will not display as expected in some or all of the other browsers. |
| Q-48 | JavaScripts and PERL scripts are examples of what?
|
|---|
A | Plain text files that can be written using any text editing application. | Explanation | Plain text files that can be written using any text editing application.
JavaScript is interpreted by the browser, while PERL scripts are run on the server. Both can be written using a text editor.
Visual Basic Script (VBScript) is different from Java and PERL. VBScript may require Microsoft's Internet Explorer to run correctly. |
| Q-49 | You want to implement ASP (Active server Pages) on your sites server. What must be in place before you can use these types of pages?
|
|---|
A | IIS | Explanation | IIS
Internet Information Server is the Microsoft's implementation of the Web server. If you need to have ASP (active server pages), you must use IIS. |
| Q-50 | What is Microsoft's preferred server-side scripting language called?
|
|---|
A | Active Server Pages (ASP) | Explanation | Active Server Pages (ASP)
If you need to have ASP (active server pages), you must use IIS, Microsoft's Internet Information Server. |
| Q-51 | What is the second line of MIME? |
|---|
A | Content Type | Explanation | Content line
The concept behind the MIME format is simple: instead of assuming that e-mails are plain text, MIME allows the sending computer to specify the specific details of the content itself (such as its content-type and encoding type). In comparison to a standard e-mail, MIME formatted e-mail includes three extra headers: MIME-Version, Content-Type and Content-Transfer-Encoding. Take a look at the MIME encoded email below. You might have to scroll down to see all of it.

| Q-56 | What is the most common way of getting information from a web surfer?
|
|---|
A | An HTML form | Explanation | An HTML form
Forms are used for the input of data that will be sent to the server for processing. An example of the form is the e-mail form that is widely used on the Internet. A user can fill out the form and send the data to the server. The HTML tag to start the form is [form]. It requires the closing tag [/form]. |
| Q-57 | Where do most search engines get their information about sites from? |
|---|
A | META tags | Explanation | META tags.
The [META] tags go inside the [HEAD] ...[/HEAD] tags. [META] tags are used to include the site's description and keywords that search engines use to index sites. META tags must have attributes. Usual attributes are "name" and "content". For instance: [META name="copyright" content="author name"] |
| Q-58 | What does LANG do?
|
|---|
A | Tells the browser what type of language to expect in the page. | Explanation | Tells the browser what type of language to expect in the page.
This helps search engines and browsers understand different languages as being different languages rather than just misspelled English.
For example: SPAN LANG="es"]el Taladro de Examen le da muchos de preguntas de práctica y las explicaciones que cubren todos los objetivos de examen verdaderos. [/SPAN]
The LANG sub-command does not translate. You must still write the text in the native tongue. The LANG command just allows the search engines to recognize that section as Spanish text. Here are some other codes: ar (Arabic), de (German), el (Greek), fr (French), he (Hebrew), hi (Hindi), ja (Japanese), it (Italian), nl (Dutch), pt (Portuguese), ur (Urdu), ru (Russian), sa (Sanskrit), zh (Chinese).

The closing [title] tag needs to be changed to [/title]. The closing [html] should be closed ([/html]) but if you try making this simple web page with a text editor you will see that even if the closing [/html] tag is left out there is no change. |
| Q-60 | Under what circumstances may a webmaster use content from another site and place it on his own site? |
|---|
D | He is doing a parody. | Explanation | He is doing a parody.
A parody exists when one imitates a serious piece of work, such as literature, music or artwork, for a humorous or satirical effect. A parody, because it is a method of criticism, must inevitably make use of another creative work. This often creates a conflict between the creator of the work that is being parodied and the creator of the parody. It is also highly unlikely that a copyright owner will grant permission to a parodist to use their copyright protected work in creating a parody.
Since copyright law prohibits the substantial use of a copyrighted work without permission of the copyright owner, it may be necessary for the parodist to rely on the fair-use defense to forestall any liability for copyright infringement.

| Q-63 | A friend gives you a gif graphic to use on your web page. What should you check before using it? |
|---|
A | If it is copyrighted. | Explanation | If it is copyrighted.
It is always wise to make sure you aren't using copyrighted material on your web page. Some graphics design software programs include a feature to embed a copyright notice in the graphics file in a form of a digital signature called a watermark. The watermark is not visible on the picture, but can be viewed with many graphics software.
If the file were corrupted, it would not display properly and you would easily notice that. A graphic does not need to be compatible with web servers, the server simply stores it and allows it to be downloaded when requested by browsers. We may also safely assume that browser can display gif files. |
| Q-64 | Copyright protecting your original work is ________? |
|---|
C | Not required, but highly recommended | Explanation | Not required, but highly recommended
Notice and registration may be necessary in order to sue an infringer for damages and attorneys fees. Preferred notice is given by affixing the copyright symbol ["©", "(c)", "Copr."], date of first publication, and name of owner to the work. |
| Q-65 | How many years does a copyright offer protection for an invention? |
|---|
B | 0 years | Explanation | 0 YEARS
Copyrights offer no protection for inventions. Inventions must be protected by patents, which are much more difficult to obtain. (Copyrights are automatic as long as the creators can prove they are the original creator.) |
| Q-66 | How should a copyright appear in a "head" section? |
|---|
B | [META NAME = "COPYRIGHT" CONTENT = "Year and Your name"] | Explanation | [META NAME = "COPYRIGHT" CONTENT = "Year and Your name"]
This tag allows you to define when your page was created. As the writer of your page you hold the copyright to the material on it. This does not allow you to claim the copyright on other people's works even if their work appears on your page.
|
| Q-67 | If an author dies two years after obtaining a copyright, how many total years does the copyright last? |
|---|
B | 72 years | Explanation | 72 years
Previous to 1998 that a work was protected for 50 years after an authors death before it passed into the public domain. This law has been changed several times, most recently in October of 1998. Here is an excert from the US federal statute. (17 U.S.C. § 101 et.seq) Sec. 302.
"Duration of copyright: Works created on or after January 1, 1978
(a) In General. Copyright in a work created on or after January 1, 1978, subsists from its creation and, except as provided by the following subsections, endures for a term consisting of the life of the author and 70 years after the author's death."

| Q-68 | Using a portion of a document protected by copyright as long as it does not take away from the original document, or is used for an educational purpose falls under the realm of which of the following? |
|---|
D | Fair use | Explanation | Fair Use
The legal concept of "fair use" permits the use of copyrighted material under certain limited conditions. For the most part, the determining factors for the "fair use" concept usually come down to the size of the excerpt and whether or not the party using the copyrighted material is using it for profit.
The general idea is as follows:
1) If the copyrighted material is being used for a non-profit application, it is more likely to fall under the "fair use" concept.
2) If the copyrighted material is being used in a factual report, it is more likely to fall under the "fair use" concept than if used as part of a "creative" work. After all, something that is "creative" should be original, rather than copied.
3) The amount of the copyrighted document being used is important for it usage to fall under the "fair use" concept. If the copyrighted material constitutes a large portion of the new work, it probably won't qualify as fair use.
4) If usage of the copyrighted material may cause a loss of revenue for the copyright holder, it is not likely to be considered fair use. |
| Q-69 | In order to be copyrighted, an original work must be registered. |
|---|
A | False | Explanation | False
Copyrights are now automatic when the work is "fixed." Notice and registration are not required. But registration may be necessary in order to sue an infringer for damages and attorneys fees.
Notice is given by affixing the copyright symbol ("©", "(c)", "Copr."), date of first publication, and name of owner to the work. To read more on the copyright laws you can go directly to the source http://www4.law.cornell.edu/uscode/17/ |
| Q-70 | What is another word for unsolicited e-mail advertising?
|
|---|
A | Spam | Explanation | Spam
Electronic junk mail or junk newsgroup postings. Spam is generally e-mail advertising for some product sent to a mailing list or newsgroup. In addition to wasting people's time with unwanted e-mail, spam also wastes network bandwidth. But because the Internet is public, there is really little that can be done to prevent spam. |
| Q-71 | In order to have copyright protection, a work must be what?
|
|---|
A | Must be an original creation. | Explanation | Must be an original creation.
US copyright law protects any published or unpublished original material. The copyright protection starts from the time that material has been created. Copyright protection is automatic. It is not necessary to register your work with any US copyright office. It is recommended that you put a copyright notice on your web site and include the "©" symbol and the year that material was first published. Even if no copyright notice is included, the material is still protected under copyright law. |
| Q-72 | A webmaster from one site "borrows" content from another site and places it on his own. The content was protected by copyright and the Webmaster did not obtain permission to use it. Under what circumstance can the Webmaster do so without legal ramifications?
|
|---|
A | If the Webmaster is doing a parody. | Explanation | If the Webmaster is doing a parody.
Copyright is the legal right granted to an author (including composers, a playwrights, etc.) to exclusive publication, production, sale, or distribution of a his or her own work. A parody is an imitation of a style in which what is written on one subject is altered, and applied to another by way of burlesque or travesty.

| Q-73 | What is the easiest way to add search capabilities to your web site?
|
|---|
A | Index Server | Explanation | Index Server
The easiest way to add search capabilities to your site is to add an Index server. An Index server will automatically index your site. After entering keywords, the index server returns the pages that are most relevant. |
| Q-74 | As the Director of Development you are planning a new web site for your company. A recent study of your users shows browser usage :
23% use Netscape Navigator or Internet Explorer 5.x
36% use Netscape Navigator or Internet Explorer 4.x
7% use Netscape Navigator or Internet Explorer 3.x
26% use AOL 4.x or higher
8% use another browser
Your goals are to minimize costs, make the site accessible to as many users as possible, but also take advantage of some of the latest development technologies. Which policy would be most appropriate? |
|---|
D | 85% policy | Explanation | 85% policy
The 85% policy is to use technology that will be accessible to 85% of your users. This is the most appropriate policy to meet the user's needs and the site goals.
An Adaptive Content Policy uses Differential Content and Degradation to show appropriate content depending on the browser. On websites designed with Differential Content the server checks to see which browser is being used and sends appropriate content only. With Degradation, the website is designed in such a way that advanced features are just ignored by browsers that can't handle them. Although this would seem to be a good policy, it is often complex and costly, which doesn't match the criteria for the site.
In the Lowest Common Denominator policy, the website is designed for almost any user, including those with much older browsers. This will capture the entire audience of users, but will not allow the use of more advanced Internet development technologies.
A captive audience policy assumes that the users will want to see the content of the website so much that they will be willing to upgrade or change to whichever browser is needed. However, this will limit the number of users who will access the site. |
| Q-75 | You want to allow members of your organization to send e-mail to all other members of your organization. Which server would be the one for you to use?
|
|---|
C | Directory | Explanation | Directory
A directory server is not simply a form of database, but a specialized server for directories. A directory can be distinguished from a general-purpose database by the usage pattern. A directory contains information that is often searched but rarely modified. Host names or user names, for example, are assigned once and then looked up thousands of times. Directory servers are tuned for this type of usage, whereas relational databases are much more geared toward maintaining data that's constantly changing. |
| Q-76 | Which of the following is a standard protocol used on the Internet to ensure secure online payment by credit card? |
|---|
D | SET | Explanation | SET
SET is an acronym for Secure Electronic Transactions, a technology being developed to increase the security and privacy of online purchasing with credit cards.
Electronic Data Interchange (EDI) is the interorganization exchange of documents in standardized electronic format directly between participating computers. It can be thought of as an electronic replacement of many paper-based transactions, such as purchase orders, invoices, bills of material, and material releases.
The protocol that is commonly used to send secure Web pages over the Internet is Hypertext Transfer Protocol Secure (HTTPS).
Secure Sockets Layer (SSL) is the technology that encrypts Web traffic. |
| Q-77 | You have a business and you would like to share and exchange information exclusively with other businesses of the same type. Which of the following would you use to achieve this.? |
|---|
A | Extranet | Explanation | Extranet
An EXTRANET would be the best option because it could be confined only to the companies you wish to exchange information with.
A VPN would be very secure but not necessary because you don't need a high level of security.
A supernet is to do with IP addressing
The Internet could be used, but it would be less private than an extranet. |
| Q-78 | Which of the following would provide shopping cart/ trolley services for your web site?
|
|---|
A | Merchant Services | Explanation | Merchant Services
Merchant Services provide shopping cart/trolley facilities for e-commerce sites. Merchant Services can include a virtual storefront and shopping carts.

| Q-79 | You use a database on your e-commerce site. In order for your browser to connect to that database what do you need to create? |
|---|
A | DSN | Explanation | DSN
A Data Source Name is a unique name that identifies the database. |
| Q-80 | You are building a website and it is very important to you that users get information from the website based on their preferences. Which of the following will best help you achieve this? |
|---|
A | Relational database | Explanation | Relational database
A relational database will enable you to store user preferences, because it can keep track of sets of data with multiple relationships. Data mining programs analyze data and draw conclusions from the analysis. Flat databases will not deal with multiple relationships. |
| Q-81 | You make a web page with a text editor with the text, "Welcome to my new web site!" However when you look at the page in a browser you do not see any text displayed. What should you change? |
|---|
A | bgcolor="#800000" | Explanation | bgcolor="#800000"
As you can see the body text and the bgcolor (background color) have identical values. In this case maroon. Therefore your text is still there but you wrote with maroon chalk on a maroon blackboard.
If you have ever saved a web page to read later and it had colored background it could use an enormous amount of ink if you wanted to print it. By editing the HTML source you would save ink and possibly make it easier to read. Just open the page in a text editor and change the value of bgcolor to FFFFFF (that is white) save it and when you open the page with a browser the background will be white. |
| Q-82 | You would like to have 30 seconds of music play while Internet users view your web page. You upload the MIDI file to your web server and add the following HTML to your web page. However, when you view the page the music repeats endlessly. This is very annoying. What line could you add to prevent this? |
|---|
A | loop = FALSE | Explanation | loop = FALSE
The corrected HTML would look like this.
[EMBED src = "MIDI/Classical/stones.mid"
width = 200
height = 60
loop = FALSE
align = right
]
When embedding sounds in web pages it is also a good practice to embed them later in the page. If a viewer has to wait for your MIDI file to load before seeing the page he or she will probably just click away. |
| Q-83 | What graphic file format supports partial transparency?
|
|---|
A | PNG | Explanation | PNG
PNG (Portable Network Graphics) supports transparency and interlacing and offers better compression than GIF. PNG also supports partial transparency. GIF supports transparency but the question was specifically asking for "partial" transparency. |

| Q-86 | How does streaming media formats allow for slowdowns in the data stream? |
|---|
D | Building up a buffer of data before playback begins. | Explanation | Building up a buffer of data before playback begins.
Streaming video formats generally use a buffer to store several seconds worth of data so the player can draw data from the buffer when the transmission slows down. |
| Q-87 | What digital standard has a high compression rate because it only stores changes between frames?
|
|---|
A | MPEG | Explanation | MPEG
MPEG (Moving Picture Experts Group) Files are compressed digital video files considered to be of higher quality than QuickTime and others. Compression is done by only saving the changes between images instead of all the images. |
| Q-88 | How do streaming media formats allow for slowdowns in the data stream?
|
|---|
A | By building up a buffer of data before playback begins. | Explanation | By building up a buffer of data before playback begins.
This is a big improvement over having to wait until an entire song or movie has downloaded before it begins playing. |

VRML is to 3D graphics what HTML is to text: it is a common format that can be displayed on any computer using a standard WWW browser or using a standalone viewer. Complex 3D crystal structures can be described in VRML, including space filling, ball-and-stick, co-ordination polyhedrae etc.. They can be explored from the inside with full interactivity. |
| Q-96 | What is the color depth of JPEG? |
|---|
C | 24 bit | Explanation | 24 BIT
A Joint Picture Expert Group (JPEG) format is the preferred format for color photos to be displayed in a web browser. JPEG is a more compact file format and supports different levels of compression. A fundamental advantage of JPEG is that it stores full color information. That is 24 bits / pixel or 16 million colors. |
| Q-97 | Which standard only stores changes between frames to enhance the compression rate? |
|---|
D | MPEG | Explanation | MPEG
MPEG achieves high compression rate by storing only the changes from one frame to another, instead of each entire frame. The video information is then encoded using a technique called DCT. |
| Q-98 | Which standard supports the animation of graphics?
|
|---|
B | GIF89A | Explanation | The current GIF (Graphics Interchange Format) standard is GIF89a.
It supports transparencies, animation and interlacing. GIF format only supports 256 colors. GIF is best suited for logos, icons, and clipart. Transparent GIFs are very popular in web design.

| Q-103 | Which is a server side script?
|
|---|
A | PERL | Explanation | PERL
Two most popular types of server side scripts standards are CGI ( Common Gateway Interface) and ISAPI (Internet Server Application Programming Interface). CGI scripts can be written in many programming languages. PERL (Practical Extraction and Report Language) and C are probably the most popular for writing CGI scripts. |
| Q-104 | CGI is parsed on which of the following?
|
|---|
A | On the server | Explanation | Server
Common Gateway Interface is a program language that runs on servers and provides a means to customize output to the user. It is server-based and performs all operations on the server (versus ActiveX and Java applets, which run on the client). Because a process must be initiated each time the program is run, CGI tends to be server-intensive. |
| Q-105 | With a 56 Kps connection, how would it take to download 7000 bytes of data?
|
|---|
A | 1 second | Explanation | 1 second
56000 bits per second / 8 bits per byte = 7000 bytes per second. In reality it would take a bit longer considering that the data packet involved is not alone. It has been joined by data headers and trailers that are unimportant for I-Net+. For instance, at the Data Link layer, framing is used to encapsulate the data packet with control information for transmission on a local network. At the network level, routers use the logical address in a network layer header to determine the next hop router to forward the packet to.
But, of the choices listed 1 second is the best choice and the formula above is the formula that should be used.
|
| Q-106 | What would be the best choice for a 10 Mbps connection to your office? |
|---|
D | T3 | Explanation | T3
A 56 Kbs modem is obviously too slow. In fact if you used a bank of 56 Kbs modems and bundled all of their bandwith together into one connection you would need about 180 modems to give you the required 10 Mbs. ISDN would provide a connection speed of 128 Kbs, far below the required 10 Megabits required. T1 also would be too slow. Below is a list of some connections and their speeds.
T3 = 45 Mbps
T1 = 1.544 Mbps
ISDN = 128 Kbps |
| Q-107 | Which protocol gives you higher download speed than upload speed? |
|---|
A | ADSL | Explanation | ADSL
ADSL (Asymmetric Digital Subscriber Line) provides reasonably fast upload transmission speeds (up to 640 Kbps) and very fast download speeds (up to 9 Mbps). |
| Q-108 | Which one is a valid mac address?
|
|---|
A | 03:c3:a1:f2:34:c4 | Explanation | 03-c3-a1-f2-34-c4
213.122.10.10 --- This is an IP address.
102.54.94.97 winners.examdrill.com # source server --- This is a host file entry.
03:c3:f2:34:c4 --- This one is only 5 bytes long.
MAC addresses are 6 byte hexidecimal numbers. You may see the printed with colons or spaces separating the bytes.
Try running Winipcfg (if you're using Windows 95 or Windows 98). Your MAC address will be dispalyed as the "Adapter Address". |
| Q-109 | What command resets the modem? |
|---|
B | ATZ | Explanation | ATZ
The instructions from your computer to you modem which configure it, dial it and decide how it handles data transmission are referred to as the Hayes Command Set. As more players enter the modem market and modems become more sophisticated, the set has been extended and occassionaly a manufacturer will alter the command set on their modem.
ATZ - Resets modem to power up defaults
ATDT - Dials number as a tone
ATDP - Dials number as a pulse
ATA - Answers incoming call manually
ATH - Hangs up modem |
| Q-110 | Where do ISPs connect to form the Internet backbone? |
|---|
B | NAP | Explanation | NAP (Network Access Points)
A NAP is a network exchange facility where Internet Service Providers (ISPs) connect with each other. The NAPs determine how traffic is routed and are also the points of most Internet congestion. |
| Q-111 | How long would it take to download 7K file using a 56K modem connection?
|
|---|
D | 1.25 Seconds | Explanation | 1.25 Seconds
7000 bytes equals 56000 bits (1 byte = 8 bits). You may be tempted to think you could just divide 56,000 by 56,000 and it would be 1 second. However, it's not that simple. There is always a certain amount of additional bits involved in dividing the data into packets and also for error correction. Under ideal conditions, the minimum amount of time would be 1.25 seconds |
| Q-112 | Networks with a B class IP address supports how many host? |
|---|
B | 65,534 | Explanation | 65,534
An IP address is a 32 bit binary number that is divided into 4 octets. Depending on the class of the address it will have one, two or three octets dedicated to the host portion. if it is a class A address then there will be three octets or 24 bits dedicated to the host portion. Class B uses the last two octets and Class C only the last octet. Look at the following formula.
Class A 2 (for counting in binary) raised to the 24th power - 2 unusable addresses = 16,777,214
Class B 2 (for counting in binary) raised to the 16th power - 2 unusable addresses = 65,534
Class C 2 (for counting in binary) raised to the 8th power - 2 unusable addresses = 254 |
| Q-113 | What is a dead zone? |
|---|
A | A segment between routers using a protocol other than TCP/IP . | Explanation | A segment between routers using something other than TCP/IP .
A way to protect networks from TCP/IP attacks like SYN floods and ping of death attacks. These attacks cannot get past the non-TCP/IP zone. For example, if an internal segment is running IPX/SPX the PING or SYN attacks will not be able to pass through the dead zone and therefore will be effectively stopped. |
| Q-114 | What is the server called that enables a range of private IP addresses on internal intranet, while still allowing user to access the Internet? |
|---|
C | NAT | Explanation | NAT (Network Address Translation Service)
NAT is an Internet standard that enables a LAN to use one set of IP addresses for internal traffic and a second set of addresses for external traffic. Proxy servers use NAT. |
| Q-115 | What is the least secure? |
|---|
D | Internet | Explanation | Internet
The Internet does not require an access control list therefore it is open for everyone.
VPNs (Virtual Private Networks) provide a high degree of security. Intranets are insulated from the Internet (or should be). Security problems are limited to internal users, as long as proper precautions to protect it from external attack from the Internet. Extranets general have security measures such as VPNs and firewalls in place. |
| Q-116 | Which network device is not affected by a virus? |
|---|
B | Hub | Explanation | Hub

A | SLIP | Explanation | SLIP (Serial Line Internet Protocol)
SLIP is a TCP/IP only protocol. PPP has a number of advantages over SLIP; it is designed to operate both over asynchronous connections and bit-oriented synchronous systems and it can configure connections to a remote network dynamically, and test that the link is usable. PPP can be configured to encapsulate different network layer protocols (such as IP, IPX, or AppleTalk) by using the appropriate Network Control Protocol (NCP). |
| Q-127 | If you want to have secure communications on your Intranet, what must you implement in order to create your own key pairs?
|
|---|
A | A certificate server | Explanation | A certificate server
The certificates are used for data encryption and also for authenticating web sites. |
| Q-128 | What bandwidth technology uses a 53 byte cell?
|

| Q-129 | Microsoft's implementation of the Web Server is called what?
|
|---|
A | IIS | Explanation | IIS
Internet Information Server is the Microsoft's implementation of the Web server. If you need to have ASP (active server pages), you must use IIS. |
| Q-130 | What is directly connected to the Internet Backbone. |
|---|
A | NAP | Explanation | NAP
Short for Network Access Point, a public network exchange facility where Internet Service Providers (ISPs) can connect with one another in peering arrangements. The NAPs are a key component of the Internet backbone because the connections within them determine how traffic is routed. They are also the points of most Internet congestion. |
| Q-131 | Which network hardware device will improve network performance? |
|---|
A | Router | Explanation | Router
Of course in given situations each of the choices listed would improve network performance. But routers make inteligent decisions about where to send packets based on their network layer address. They increase security by isolating diferent segments of a network. They also reduce trafic by filtering out unwanted trafic or broadcast trafic. |
| Q-132 | What is the specification known as that connects the users on an Ethernet to the Internet through a common broadband medium, such as a single DSL line, wireless device or cable modem? |
|---|
A | PPPoE | Explanation | PPPoE
Acronym for Point-to-Point Protocol over Ethernet. PPPoE relies on two widely accepted standards: PPP and Ethernet. PPPoE is a specification for connecting the users on an Ethernet to the Internet through a common broadband medium, such as a single DSL line, wireless device or cable modem. All the users over the Ethernet share a common connection, so the Ethernet principles supporting multiple users in a LAN combine with the principles of PPP, which apply to serial connections. |
| Q-133 | Your company has recently started marketing in France. Your customer support staff reports a number of emails from French users complaining about the speed of the site. What would improve the download times in France? |
|---|
C | create a mirror site in France | Explanation | create a mirror site in France
Creating a mirror site that is serviced by a server in Europe would improve download speeds. The biggest bottleneck for international users is frequently intercontinental bandwidth.
Increasing your server bandwidth will not impact the bandwidth running between the two continents.
Creating a website in French may make your French customers happier, but will not speed their download times.
RAID 1 (Redundant Array of Independent Disks level 1) is also known as mirroring, however, it generally refers to mirroring data on hard disks, not on web sites. Changing to RAID 1 would not affect download times.

| Q-134 | Client B accesses resources in the Exam Drill LAN. He does this using a 56 Kps modem connection to the Internet. The communication is encryted with IPSec and tunneled with L2TP. What type of connection is this? |
|---|
C | VPN | Explanation | VPN
Virtual Private Networks are built using PPTP or other tunneling protocols to provide encrypted (secure) communications across the Internet. They are used for connecting two different company sites such as with an Extranet, or for allowing a remote user to securely access a site. |
| Q-135 | What type of network technology enables a range of private IP addresses on internal intranet, while still allowing user to access Internet? |
|---|
C | Network Address Translation | Explanation | NAT
NAT takes a private IP address for a network client and converts it to a public IP address for use on the Internet. This permits a large number of users to access the Internet using a single registered IP address. This is also called a proxy |
| Q-136 | Which modem command checks to see if th modem is configured correctly? |
|---|
A | AT | Explanation | AT
To test the modem, give the command: AT ..(in capital letters), then press the Return key. The modem should reply: OK ..if you don't see an "OK" the modem isn't working. This could be because you chose the wrong baud rate, or because the modem isn't connected to the correct port, or because the modem isn't working. Is it plugged in? If the modem isn't working, try to borrow a working modem and try again. |
| Q-137 | What is the total bandwidth of all channels on a PRI circuit?
|
|---|
F | 1.544 Mbps | Explanation | 1.544 Mbps
ISDN can either be Basic Rate ISDN (BRI) or Primary Rate ISDN (PRI). BRI is two 64 Kbps B Channels for data and one 16 Kbps D Channel for link management.
PRI is 23 B Channels and 1 D Channel in the US or 30 B Channel and 1 D Channel in Europe. Each of these channels are 64 Kbps.

| Q-138 | Liam is having problems viewing pages on a particular website. Sometimes his browser displays the proper page, but sometimes his browser displays pages that seem to be out of date.
The website's help desk has told Liam that the problems he is experiencing with their website are related to web page caching. Liam checks the Temporary Internet File settings in Microsoft Internet Explorer 5.0, and it is set to check for newer versions automatically. How would it be best for Liam to change his settings? |
|---|
C | Change his Temporary Internet File settings to check for new versions every visit to the page. | Explanation | Change his Temporary Internet File settings to check for new versions every visit to the page.
Temporary Internet Settings are Microsoft's term for caching web pages. They determine how often stored web content should be updated on the client's computer. Liam's current setting (Check for Newer Versions Automatically) will check for new content only when Liam is returning to a page viewed on a previous day. Internet Explorer 5.x will monitor how often the page changes, and will refresh the content accordingly.
Liam should change his settings to check for new versions every visit to the page. This will ensure the content displayed by the browser is the most up-to-date. If he changes his settings to never check for new versions, he will always be using the content stored on his computer, and the information will never refresh. If he changes his settings to check for new versions every time he starts his browser, then the information will not refresh until he closes his browser and re-opens it. There is not an option to check for new versions once a day. |
| Q-139 | In what way are Boolean operators helpful during an advanced Internet search? |
|---|
C | They narrow searches by using AND, OR, and NOT statements. | Explanation | They narrow searches by using AND, OR, and NOT statements.
Boolean operators are used to narrow or restrict searches to specifically combined or excluded terms using the AND, OR, and NOT statements. Some search engines also use the NEAR operator and allow you to specify a phrase by enclosing it in quotation marks. You can also use parentheses to group operator phrases. Boolean operators do not include IF/THEN statements.
Searches using Boolean operators are considered advanced searches. A simple search for a single word would not benefit from using Boolean operators. Boolean operators do not allow you to search multiple search engines simultaneously. However, there are some meta search sites that offer that feature.

| Q-140 | MIME is an acronym of which of the following? |
|---|
A | Multipurpose Internet Mail Extension | Explanation | MIME is short for Multipurpose Internet Mail Extensions
MIME is aa specification for formatting non-ASCII messages so that they can be sent over the Internet. Most email clients now support MIME, which enables them to send and receive graphics, audio, and video files via the Internet mail system. In addition, MIME supports messages in character sets other than ASCII.
There are many predefined MIME types, such as GIF graphics files and PostScript files. It is also possible to define your own MIME types.
In addition to e-mail applications, Web browsers also support various MIME types. This enables the browser to display or output files that are not in HTML format.
MIME was defined in 1992 by the Internet Engineering Task Force (IETF). A version, called S/MIME, supports encrypted messages |
| Q-141 | With which of the following can cookies can be set?
|
|---|
A | JavaScript | B | Http header | C | MIME | D | UDP | Ans | ab | Explanation | JavaScript
Http header
The purpose of cookies is to remember certain information about the user when the user accesses the web site. To set the cookie, the web server uses “Set cookie” command in the HTTP header. Cookies can also be set with the JavaScript. |
| Q-142 | PHP is a server side script. |
|---|
A | True | Explanation | True
PHP Hypertext Preprocessor is a server-side, HTML embedded scripting language used to create dynamic Web pages. In an HTML document, PHP script is enclosed within special PHP tags.
Because PHP is embedded within tags, the author can jump between HTML and PHP instead of having to rely on heavy amounts of code to output HTML. And, because PHP is executed on the server, the client cannot view the PHP code. PHP is specifically mentioned in Comptia's I-Net+ list of objectives.
|
| Q-143 | Which language allows for the creation of platform independent executables? |
|---|
A | Java | Explanation | Java
Java programs can run on any platform that has a compatible Java Virtual Machine installed on it.
C++ and Visual Basic programs must be compiled for the specific Operating System your machine is running.
Perl, VBScript, and JavaScript are scripting languages and are not compiled into executables. |
| Q-144 | What is Microsoft's preferred server-side scripting language?
|
|---|
A | Active Server Pages (ASP) | Explanation | Acitive Server Pages (ASP)
You can use several interpreted scripting languages with ASP, including VBScript, JScript, and JavaScript. However, ASP is optimized to work with VBScript and ActiveX components. This is why it's Microsoft's preferred server-side scripting language. If you need to have ASP, you must use IIS. |
| Q-145 | A user with a 128 Kbps ISDN modem will take about how many seconds to download a 100 Kilobyte file?
|
|---|
A | 8 | Explanation | 8
128 Kilobits per seconds is (divided by 8) is 16 Kilobytes per second. 100 Kilobyte file / 16 Kilobytes per second = 6.25 Seconds. But if you add the headers and trailers that are added to a packet during transmission the closest answer here is 8. If only the actual 100 Kilobyte file were sent over the wire it would not know where it came from or where it was supposed to go. It would also have no security being, as it were, naked on the wire. |
| Q-146 | You created a form on your site that takes the data from the user and sends it to the server. What is the most effective way to make sure the data is entered in a specific format?
|
|---|
A | Validate on the browser with JavaScript | Explanation | Validate on the browser with JavaScript
Javascript is a strong tool for validating forms before sending the content. The validation can take place as the visitor enters values, or all at once upon clicking the submit button after entering the values.
Each validation function can easily be customized to fit the needs of the fields they are checking. |
| Q-147 | A Unicode character set uses how many bits to represent each character?
|
|---|
A | 16 | Explanation | 16
Unicode is a 16-bit character encoding that contains all of the characters in common use in the world's major languages. Unicode provides an unambiguous representation of text across a range of scripts, languages and platforms. |
| Q-148 | Which allows multiple "virtual Servers", each using different DNS names, to be resolved to the same IP address? |
|---|
A | HTTP 1.1 | Explanation | HTTP 1.1
HTTP - HyperText Transfer Protocol, the client-server TCP/IP protocol used on the World Wide Web for the exchange of HTML documents. It conventionally uses port 80. The current version is HTTP 1.1 One of the features of HTTP 1.1 is the “Host Header”. Host header makes it possible to have multiple virtual servers with the same IP address. |
| Q-149 | Based on speed and cost, which Internet bandwidth link type would be the best choice
for a small ISP serving 100 dial-up users? |
|---|
B | T1 | Explanation | T1
The beauty of a fractional T1 connection is that you can rent more channels if you need it. A T1 connection has 24 different channels each is 64 Kb (24 X 64 Kb = 1.536 Mbps). You may notice that a T1 is actually 1.54 Mbps those extra 8 Kbps are overhead for managing the connection.
If we divide 1.536Mbps by 100 users each user is only allotted about 15 Kbps for their connection. But ISPs can assume that not all of their users will be online at the same time. If this connection speeds are inadaquate the ISP can simply rent more T1 channels.
A T1 line runs at 1.544 megabits per second and will support about 50 to 75 simultaneous users. A DS3 (a.k.a. T3) line operates at 45 megabits per second and can support several thousand simultaneous users. This would be overkill for a small ISP.
56 Kb and ISDN is too slow for even a small ISP.
|
| Q-150 | Which connection operates at speeds of 51.85 Mbps? |
|---|
A | OC-1 | Explanation | OC-1
Short for Optical Carrier, specifies the speed of fiber optic networks conforming to the SONET standard. OC-3 (three times the speed of OC-1) operates at speeds of 155.52 MBPS - Fiber optic standard in use today.
|
| Q-151 | Which of the following best describes DSL?
|
|---|
B | DSL stands for Digital Subscriber Line, a direct Internet connection method that uses digital phone lines and a DSL modem. | Explanation | DSL stands for Digital Subscriber Line, a direct Internet connection method that uses digital phone lines and a DSL modem.
Digital Subscriber Line (DSL) is a high-speed continuous (direct) method of Internet access. It connects to the Internet through a DSL modem and uses digital phone lines for transmission. DSL connections can operate at rates of 512 Kbps to 10 Mbps, depending on factors such as network traffic. |
| Q-152 | Which uses a fiber optic line to connect ISPs to the Internet at 45 Mbps? |
|---|
A | T3 | Explanation | T3
Below are some connection types and their relative speeds:
T1 1.54 Mbps
E1 2.048 Mbps This is the European standard comparable to T1.
T3 45 Mbps - Also called DS-3
OC-1 51.8 Mbps - OC stands for optical carrier.
OC-3 155.52 Mbps - This is the fiber optic standard in use today.
|
| Q-153 | Which Internet bandwidth technology is widely used as an Internet backbone, but rarely used to connect ISPs to the backbone? |
|---|
A | ATM | Explanation | ATM
Primary National Service Providers collectively operate what is often referred to as the Public Internet Backbone. Each Primary National Service Provider operates one or more Wide Area Networks, typically using either Frame Relay and/or ATM. Frame Relay is also used for slower connections. |
| Q-154 | What type of transport protocol is UDP? |
|---|
A | Connectionless | Explanation | Connectionless
This means that the packets are sent on their way without a guarentee that they will arrive. This decreases the overhead (the bits that encapsulate and accompany the data payload like the envelope and packaging in a snail-mail delivery) but this means that User Datagram Protocol (UDP) is considered "unreliable" as well as fast. |
| Q-155 | Which network device allows you to communicate with a host that uses a different protocol stack? |
|---|
A | Gateway | Explanation | Gateway
A gateway is used to connect networks with different protocols like TCP/IP network and IPX/SPX networks. If you only have NetBEUI protocol on your network and need to access the Internet (TCP/IP is the protocol on the Internet), you would need to use a Gateway. |
| Q-156 | You use a proxy server for all of your company's 150 employees to connect to a web site. The web site's server keeps a record of all IP addresses that connect to the site. How many of your company's IP addresses will be logged onto the site's server? |
|---|
C | Only the IP address of your company's proxy server. | Explanation | Only the IP address of your company's proxy server.
Proxy servers use Network Address Translation (NAT) to allow many PCs to connect to the Internet, but only the proxy server's IP address is seen by the Internet. |
| Q-157 | Which tunneling protocol supports flow control and encryption?
|
|---|
C | PPTP | Explanation | PPTP (Point to Point Tunneling Protocol)
PPTP is used to create virtual private networks. It supports encryption and flow control. The two next best answers would be TCP which supports flow control but not encryption and L2TP which like PPTP is a tunneling protocol but does not support encryption. L2TP uses IPSec for encryption. |
| Q-158 | You cannot log onto a remote site. You made sure you are typing in the correct password. What would you try next? |
|---|
A | Hit the caps lock and retype your password | Explanation | Hit the caps lock and retype your password
Always seek the simple solution first. Most passwords are case sensitive. If the caps lock is inadvertently activated you may have typed the correct password in the wrong case. |
| Q-159 | Which is browser vendor dependant? |
|---|
A | VBScript | Explanation | VBScript
VB script is a proprietary script from Microsoft and can only be interpreted by Microsoft's Internet Explorer browsers. |
| Q-160 | What does the acronym CORBA stand for?
|
|---|
A | Common Object Request Broker Architecture | Explanation | Common Object Request Broker Architecture
Developers use CORBA to distribute applications across client-server networks. Instead of having hundreds of thousands of lines of code running on mainframe computers with dumb terminals, smaller, more robust applications that communicate between file servers and workstations are now necessary. To keep this distribution of applications simple, a plug-and- play architecture is necessary to distribute the client-server applications. The programmer then can write applications that work independently across platforms and networks.
The idea behind CORBA is a software intermediary that handles and disperses access requests on data sets. This intermediary is referred to as an Object Request Broker (ORB). The ORB interacts and makes requests to differing objects. It sits on the host between the data and the application layer (that is, one level lower than the application layer (level 7 in the OSI model). An ORB negotiates between request messages from objects or object servers and the affiliated data sets.
The goal of CORBA is to make programming easier by making CORBA- based applications highly portable. Developers now have a standardized set of facilities, as we shall see later, that they can issue on a host machine to retrieve or manipulate requested data. Using different databases and data files on one or more hosts will now go unnoticed by the user or the application. Applications become easy to integrate because the interfaces are identical.

| Q-161 | Which of the following would you use to log on to an FTP site that requires username and password? |
|---|
B | ftp://username:password@secure.website.com | Explanation | ftp://username:password@secure.website.com
After the protocol, namely ftp, username and password are separated by a colon. The password and server are separated by an ampersand (@). |
| Q-162 | Which cannot be used as a firewall? |
|---|
C | DHCP server | Explanation | DHCP server
DHCP is a server-based administration utility used to automatically assign IP addresses (among other configurations) to clients. It should never be implimented as a protection against unauthorized access. |
| Q-163 | What is it called when information is intercepted and used to impersonate a legitimate request for resources?
|
|---|
A | Spoofing | Explanation | Spoofing
Spoofing is when someone, using a protocol analyzer or other device to intercept and decode packets sent to and from the server in order to find the account ID and password, impersonates an authorized user. The spoofer then will have unauthorized access to resources using an authorized identity. |
| Q-164 | What is the process called that verifies that your login and password are correct? |
|---|
A | Authentication | Explanation | Authentication
Authentication is the process of verifying a person is who they claim to be. This is typically done by user IDs and a password. It is important to remember that PPP uses logon authentication but SLIP cannot. |
| Q-165 | Which is used for Digital Certificates? |
|---|
D | X.509 | Explanation | X.509
X.509 is the most widely used standard for digital certificates. |
| Q-166 | Someone sends you a Ping packet that is over 65,536 bytes in size and your PC hangs? |
|---|
A | Ping of Death | Explanation | Ping of Death
The Ping of Death is an attack in which your PC is caused to hang up or crash because someone sent it a Ping packet that it could not handle. Most operating systems and Ping utilities are aware of the Ping of Death now and have been patched to deal with it. |
| Q-167 | Telnet presents no security risk. |
|---|
B | False | Explanation | False
A Telnet session allows the user to interact with the remote server through the keyboard, much like if she were sitting at the server's console. This is very much a security risk. |
| Q-168 | Which of the following is an authentication protocol? |
|---|
A | Kerberos | Explanation | Kerberos
Kerberos is an authentication protocol designed to enable two parties to exchange private information across an otherwise open network. |
| Q-169 | What would you use to encrypt email using an encryption method with a private key and a public key? |
|---|
A | PGP | Explanation | PGP (Pretty Good Privacy)
PGP is a technique for encrypting messages. PGP is one of the most common ways to protect messages on the Internet because it is effective, easy to use, and free. PGP is based on the public-key method, which uses two keys. One is a public key that you distribute to anyone from whom you want to receive a message. The other is a private key that you use to decrypt messages that you receive. To encrypt a message using PGP, you need the PGP encryption package, which is available for free from a number of sources. The official repository is at MIT.
The U.S. government thought PGP was so good it brought a lawsuit against its author, Phillip Zimmerman, for putting it in the public domain and making it available to enemies of the U.S. The U.S. lawsuit was dropped, but it is still illegal to use PGP in many other countries. |
| Q-170 | Verisign is an example of: |
|---|
A | Certificate Authority | Explanation | Certificate Authority
Certificate Authorities issue digital certificates to users that binds their identity to the certificate. It schedules expiry dates for certificates and revokes them when required, publishing the fact of the revocation to a Certificate Revocation List (CRL). |
| Q-171 | What command do you use to start an FTP session? |
|---|
C | open | Explanation | open
After you have started an FTP session you need to connect to a remote computer. At the ftp] prompt type the command open followed by the hostname, which is the complete name of the remote computer or its IP address. For example:
ftp] open ftp.microsoft.com [return]
For a complete list of FTP commands go to a command prompt and type FTP then press return then type HELP and press return again. |
| Q-172 | When surfing your browser receives the message “The server is not responding”. What could be the problem?
|
|---|
A | The server is overloaded | Explanation | The server is overloaded.
The server is overloaded and therefore is not responding. |
| Q-173 | How long does it take to download a 7,000 byte file at 56 Kbs? |
|---|
A | 1.25 seconds | Explanation | 1.25 seconds
56 Kilobits per second / 8 bits per byte = 7 Kilobytes per second
Therefore, a 7000 byte file would take just over 1 second to be downloaded if one takes into consideration the overhead. Overhead is the extra headers and trailers which are attached to the data "payload". These headers and trailers are called encapsulation and are necessary for routing (destination information), filtering or security as in the case of tunneling with a Virtual Private Network. |
| Q-174 | Which network hardware device protects a server from malicious attacks over the Internet? |
|---|
A | Firewall | Explanation | Firewall
Firewalls are used to prevent unauthorized access from the external network such as Internet to your local network. Gateway, Proxy and RAS (Remote Access Server) servers can be used as firewalls but they are not by themselves firewalls. |
| Q-175 | Which is the least secure?
|
|---|
A | Internet | Explanation | Internet
The Internet is simply the biggest network with the most users and also the most potential for virus infection, hacking and malicious attacks. |
| Q-176 | How many bits are in an IP Version 4 (IPv4) address?
|
|---|
A | 32 bits | Explanation | 32 bits
Each IP address (version 4) is 32 bits long. MAC addresses are 48 bits long. |
| Q-177 | What TCP/IP protocol can be used for directory access? |
|---|
A | LDAP | Explanation | LDAP
Lightweight Directory Access Protocol, is an Internet protocol that email programs use to look up contact information from a server. LDAP was designed to adapt a complex enterprise directory system (called X.500) to the modern Internet. A directory server runs on a host computer on the Internet, and various client programs that understand the protocol can log into the server and look up entries. X.500 is too complex to support on desktops and over the Internet, so LDAP was created to provide this service with lower overhead.
Most PCs already have an LDAP-aware client installed on your computer. Most current email clients are set up to search an LDAP directory for email addresses. These include Outlook, Eudora and Netscape Communicator. |
| Q-178 | What is the default subnet mask for the IP address 194.206.42.7
|
|---|
A | 255.255.255.0 | Explanation | 255.255.255.0
An address is Class A if the first octet begins with 1-126. It has a default subnet mask of 255.0.0.0
An address is Class B if the first octet begins with 128-191. It has a default subnet mask of 255.255.0.0
An address is Class C if the first octet begins with 192-223. It has a default subnet mask of 255.255.255.0
An address is Class D if the first octet begins with 224-239
An address is Class E if the first octet begins with 240-255 |
| Q-179 | How are cookies stored? |
|---|
A | Unencrypted text file on client | Explanation | Unencrypted text file on client
Cookies are always stored on the client’s machine in unencrypted form. To set the cookie the web server uses “Set cookie” command in the HTTP header. Cookies can also be set with the JavaScript. An “expiration” date and time of the cookies can be set with the expires attribute. When expiration date has been reached, the cookie will be automatically deleted from your computer. If no expiration date is set, the cookie will expire when the browser is closed. |
| Q-180 | What is the protocol and what is the second part of the following network address:
172.16.0.254, mask=255.255.0.0
|
|---|
C | Private IP address and node number | Explanation | Private IP address and node number
You can use certain IP addresses privately within you own Intranet as long as they are not seen by the global community. These addresses are listed below:
• 10.0.0.0
• 172.16.0.0
• 192.168.0.0 |
| Q-181 | Your company's corporate headquarters is in Houston. You recently opened a second office in Seattle. You anticipate opening a third office in two years. The second office will need access to secure company information, but must limit costs. Which network would be most appropriate?
|
|---|
B | VPN | Explanation | VPN
A Virtual Private Network (VPN) combines the flexibility, reliability, and economy of the Internet with the security of a private dedicated network. Many VPNs use the Internet as the "backbone" or main connection trunk, so the backbone is basically in public domain and is not secure. Network protocol "tunneling" refers to the technique of encapsulating one protocol within another protocol. This is often done to send a LAN protocol over a network backbone that uses a different protocol, but is also done to send encrypted data over a public network.
A VPN is an encrypted "private tunnel" across the Internet. Many hosts can be interconnected into a VPN, using the Internet as the connection medium, and still have the privacy they would have if they were all connected on a private LAN. This is the most appropriate type of network since it is relatively low-cost, but provides security.
A LAN (Local Area Network) is a network that is implemented in between computers in a small geographical area. Usually computers are connected by wires to hubs and hubs to servers. Since the second office is at a great distance, a LAN is not the most appropriate network type.
A WAN (Wide Area Network) is a network that spans a large geographical area (like in the scenario posed). WANs can be connected on demand, or permanently connected. WANs are typically very expensive because lines used to connect the network are leased. This would provide security, but doesn't meet the cost requirements.
An Intranet is a collection of information that is accessed through the same software used to access the Internet. However, the information is only available internally, to company employees. Intranets need to be implemented on a physical network (such as a VPN, LAN, or WAN). |
| Q-182 | Which of the following DNS servers do not contain HOST records?
|
|---|
D | Caching | Explanation | Caching
A DNS caching server is a temporary store for DNS lookup requests. It queries the authoratative server and caches the replies. It does not store permanent records and is only used to reduce the load of repeated DNS lookup requests to the main DNS server. It also speeds up the response to browser requests as the results are stored in the cache. |
| Q-183 | Which of the following describes the correct format of a URL? |
|---|
A | protocol://hostname.domain:port/directory/subdirectory/filename.ext | Explanation | protocol://hostname.domain:port/directory/subdirectory/filename.ext
For instance,
http://www.examdrill.com:8080/exams/drills/demo.htm |
| Q-184 | What can you use to reduce broadcast storms? |
|---|
A | Use a Router | Explanation | Use a router
DHCP and WINS don't apply here. DHCP is for automatically assigning network settings to clients and WINS is for NetBIOS name resolution. A Bridge passes Broadcasts and would be of no help.
A router, however, does not pass broadcasts but rather "routes" intelligently to a destination. If the destination is not known and no default gateway (which is also a destination) is specified the packet will be dropped.
|
| Q-185 | What is the FQDN of http://files.sales.wigits.com/help/files? |
|---|
B | files.sales.wigits.com | Explanation | files.sales.wigits.com
A FQDN (Fully Qualified Domain Name) starts with a host name and continues all the way up to the top-level domain name. In the above example http is the protocol designation. files.sales.wigits.com is FQDN or the name of host and /help/files is the path. |
| Q-186 | The data transfer technology that automatically transfers updated information to a web client is called? |
|---|

| Q-211 | What will the following search return? (Choose three.)
dance and ((tango or waltz) or (Russian and African))
|
|---|
A | dance tango | B | dance waltz | C | dance tango Russian African | D | dance tango African | E | dance tango Russian | F | dance Russian African | Ans | abf | Explanation | dance tango
dance waltz
dance Russian African
Searches, like mathematical equations, are worked from the inside out. Start with the innermost parentheses: tango or waltz. " Tango" or "waltz" may be included in the search. The next innermost parentheses are: Russian and African. Because there is an "and" between these two, you will always see these two words together.
Looking at the outer parentheses, you can see that there is an "or" between. So the search could include the words "tango" or "waltz" OR the search could include "Russian African". The search would not include "tango Russian African" or "waltz Russian African."
Moving outside of the parentheses, dance has an "and" after it. This tells us that dance will always be included in the search. So the search will return "dance tango", "dance waltz", and "dance Russian African".
The search would not include "dance tango Russian African", "dance waltz Russian African", "dance Russian", or "dance African."

| Q-216 | You need to speed up the performance of your web site. One of the biggest problems is how slowly web graphics load. How can you fix this problem?
|
|---|
A | Reduce the size of graphics files | Explanation | Reduce the size of graphics files.
Use fewer colors or reduce the actual size of the image. Performance issues are often tied to graphics files being too large and taking too long to download over an ordinary modem connection. This design pitfall can be addressed by using compression algorithms on the graphic files, scaling the graphic down in size, selecting the optimal graphic file format for a particular image type, or reducing the number of colors in an image.
Proxy servers speed access to cached web pagews on the client side but does not increase the performance on the server side.
Converting "graphics" files to jpeg would result in smaller file sizes and faster graphics downloads, but you certainly would not convert ALL files to jpeg. |
| Q-217 | You have updated your email application, and need access to 150 entries in your old address book. What should you do?
|
|---|
A | Import the address book. | Explanation | Import the address book.

| Q-218 | To search the Internet for the phrase "The rain in Spain" how would need to enter your query? |
|---|
D | "The rain in Spain " | Explanation | "The rain in Spain"
To retrieve an exact parsing, you need to enter the query in quotes.
The+rain+in+Spain is incorrect because it would return any page that had the words "the" "in" "rain," "Spain," "of," and located anyplace, not just in the exact order and placement. The same is true of Rain and Spain this would retrieve all the pages with both of the words Rain and Spain anywhere on the page. |

110 is for POP3 |
| Q-245 | Which of the following protocols could be used as an alternate to POP3 for receiving e-mail?
|
|---|
B | IMAP | Explanation | IMAP
With POP (Post Office Protocol), mail is delivered to a shared server, and a personal computer user periodically connects to the server and downloads all of the pending mail to the "client" machine. All mail processing is local to the client machine. Once delivered to the PC, the messages are typically deleted from the POP server.
IMAP is a client-server mail protocol designed to permit manipulation of remote mailboxes as if they were local. With IMAP, mail is again delivered to a shared server, but the mail client machine does not normally copy it all at once and then delete it from the server. It's more of a client-server model, where the IMAP client can ask the server for headers, or the bodies of specified messages, or to search for messages meeting certain criteria.

| Q-254 | Which best defines a MAC? |
|---|
A | It is the Data Link Layer address of a NIC that can not be modified | Explanation | It is the Data Link Layer address of a NIC that can not be modified
The MAC or Media Access Control address is the Data Link Layer address of a NIC that has been burned into a NIC card, this should not be modified. |
| Q-255 | Who issues MAC addresses for NICs? |
|---|
C | NIC manufacturer | Explanation | NIC manufacturer
Each Network Card (NIC) has a burned in MAC address. You can't get a MAC address from a web site. While it is true that InterNIC, is a resource organization for the Internet, assigns each manufacturer the first 6 digits (00000C = Cisco, 00000E = Fujitsu, 00000F = NeXT, etc.) it is the NIC manufacturer that issues the unique MAC address.
Hardware addresses are 48 bits, expressed as 12 hexadecimal digits (0-9, plus A-F, capitalized). They should be written hyphenated by octets (e.g., 12:34:56:78:9A:BC). This gives a theoretical 281,474,976,710,656 addresses. This is more than 56,000 MAC addresses for each person on the planet! In practice, the address assignment policy (using flat addressing) will lead to some wastage - but even so, there are likely to be enougth addresses for ever computer, piece of networking equipment and household/office devices which could in the future be Internet enabled. |
| Q-256 | What transport technology translates names of network hosts into network addresses? |
|---|
B | Name Resolution | Explanation | Name Resolution
Name resolution on the Internet is handled by DNS. The Domain Name System (DNS) is a set of protocols and services in the TCP/IP protocol suite. To resolve (that is a fancy way to say translate) a domain name to IP address, your browser contacts a DNS server. The address of a DNS server is provided by your ISP. If the domain name is not found in your ISP's DNS, the ISP's DNS requests that information from the root domain server. The root domain server is responsible for maintaining database of top level domains like .com, .net, .org and country specific domains like .FR or RU. |
| Q-257 | You log on to your ISP regularly but you get frustrated because you are constantly disconnected and are forced to reconnect several times while surfing the web. What is the most likely cause of this?

| Q-291 | Networks with a C class IP address supports how many host? |
|---|
A | 254 | Explanation | 254
An IP address is a 32 bit binary number that is divided into 4 octets. Depending on the class of the address it will have one, two or three octets dedicated to the host portion. if it is a class A address then there will be three octets or 24 bits dedicated to the host portion. Class B uses the last two octets and Class C only the last octet. Look at the following formula.
Class A 2 (for counting in binary) raised to the 24th power - 2 unusable addresses = 16,777,214
Class B 2 (for counting in binary) raised to the 16th power - 2 unusable addresses = 65,534
Class C 2 (for counting in binary) raised to the 8th power - 2 unusable addresses = 254 |

C | Virtual Modem | Explanation | Virtual modem
ADSL technology works by taking the phone line's bandwidth between 24,000 hertz and 1,200,000 hertz and dividing it into 4,000 hertz bands, and a virtual modem is assigned to each band. Each of these 249 virtual modems transmit as best as it can with the assigned slice of bandwidth. The combinined capacity of these 249 virtual modems makeup the overall speed of the "pipe".
|
| Q-296 | How long for a 128 Kbps ISDN modem to download a 100 KB file? |
|---|
D | 8 Seconds | Explanation | 8 Seconds
Remember that bandwidth is measured in bits per second and file sizes are measured in bytes. Instead of multiplying the file size by eight, (eight bits per byte), it's best to multiply it by ten to compensate for overhead and error correction.
100KB x 10 = 1000 kb
1000 kb / 128 kb/s = 7.8 seconds
We round it off to 8 seconds. |
| Q-297 | Which AT modem command do you use for dialing? |
|---|
A | ATD | Explanation | ATD
Every modem that is called "Hayes compatible" follows a certain set of codes which tell the modem what to do. In the case of some programs, you don't have to know these commands to dial your modem, because the program does it for you. Other programs, such as KERMIT require that you know these commands to dial your modem and perform other useful functions.
The order in which the commands are issued is important. "AT" must always be the first command you type. Once you give the "D" command, any character typed after it either is executed as a subcommand of the "D" command or is dialed. Therefore, if you typed the "M0" command after the "D" command, the modem would try to dial M0 instead of trying to shut off the sound.
|
| Q-298 | JSP is an acronym which means? |

| Q-304 | CGI programs execute where? |
|---|
A | Server | Explanation | Server
CGI (Common Gateway Interface) programs are server side programs that process data that a web site's visitors type into HTML forms.
Example: The browser displays your web page with an input form on the user's PC. The user fills out the form and clicks the Submit button. The browser then creates a string that contains the names of the form elements, along with the data the user entered and sends the contents of the form back to your server. The CGI program on your server processes the string and places the data the user typed into the form into the appropriate fields in the database on the server.
CGI is the specification that defines the structure of the string. The CGI program must be able to separate the data and names of the form elements from the string.

| Q-331 | An API (Application programming Interface) that allows Java objects to send messages to Java objects running in other Java Virtual Machines anywhere on a TCP/IP network. |
|---|
A | Java RMI (Remote Method Invocation) | Explanation | Java RMI (Remote Method Invocation)
RMI provides for remote communication between programs written in the Java programming language. The Java Remote Method Invocation (RMI) system allows an object running in one Java Virtual Machine (VM) to invoke methods on an object running in another Java VM.
Object Oriented programming languages divide source code into modules or "objects". RMI allows a Java program running on one machine to access and communicate with the objects of a Java program running on a remote Java machine.
A program like Exam Drill has objects communicating and passing data between them within the memory of the local PC. Many of these objects are contained in the various "shared DLLs", like the Common Dialog DLL (used for opening files and selecting fonts) that Windows operating systems use. RMI allows this concept to extend across a network between Java programs. |
| Q-332 | Your web page looks fine on your PC, but after uploading it to the server the images are not displayed. What should you check?
|
|---|
A | Image source URL | Explanation | Image source URL
The Image Source setting in the HTML code for the page may be set to work on your PC's directory path, but the server's path may not match. You need to set the image source to match the directory structure on the server. |
| Q-333 | Web caching does not provide reduction in _________? |
|---|
D | Number of security breaches | Explanation | Number of security breaches
Browsers use WebCaching to avoid having to download the most recently used files over again. This doesn't shorten the initial download time for a specific document, but if the document needs to be accessed again, the "perceived" download time will be shortened. Since frequently accessed documents don't need to be download as often, caching also reduces bandwidth demands and the number of requests to the server. |
| Q-334 | How would object request brokers can be implemented in a multi-tiered architecture? |
|---|
A | Corba | Explanation | Corba
In a multi-tiered client/server system, ORBs (object request brokers) are what enables information to pass between totally separate and different applications, that may be operating on different platforms. ORBs are part of the Corba programming model.
The following description about Corba is from Webopedia.com
"Short for Common Object Request Broker Architecture, an architecture that enables pieces of programs, called objects, to communicate with one another regardless of what programming language they were written in or what operating system they're running on. CORBA was developed by an industry consortium known as the Object Management Group (OMG). " |

| Q-336 | What is a frequent error when developing international English language sites? |
|---|
A | Using colloquialisms | Explanation | Using colloquialisms
Communication is difficult enough with people speak the same language. Remember that the web is international, and although you may be writing in English think about people who use it as a second or third language. Do not be too colloquial. Stay away from slang and colloquial expressions which people outside your country will not be familiar with. This is more difficult than you might think. What is the correct English translation for "Beating about the bush" or "Ya know"?
|
| Q-337 | Which language is NOT interpreted by a web server? |
|---|
B | HTML | Explanation | HTML
HTML is interpreted by the browser on the client side. |
| Q-338 | You want to implement Online Transaction Processing (OLTP) in an e-commerce business application. Which of the following is needed? |
|---|
C | Relational database | Explanation | Relational database

| Q-340 | Olivia just signed up with an Internet Service Provider (ISP), and now she is setting up her e-mail client program to receive mail on her new service. To receive e-mail she needs some specific server information. Which of the following must Olivia know to receive e-mail messages from her ISP? |
|---|
C | POP3 server address | Explanation | POP3 server address
Post Office Protocol (POP) is used to download e-mail messages from an Internet POP server, which receives and stores e-mail until the user downloads it. The POP server is identified using a unique host name or IP address. Some servers use Internet Messaging Access Protocol (IMAP) instead of POP.
When you configure your e-mail client, you also usually need to supply an SMTP server address so you can send e-mail. While the mail client uses POP to retrieve mail, it uses Simple Mail Transfer Protocol (SMTP) to send mail.
You would need an address for a Network News Transfer Protocol (NNTP) server if you were configuring a client for newsgroups.
You would not need a Web server address to configure an e-mail client. |
| Q-341 | Which command opens an FTP connection?
|
|---|
A | open | Explanation | open
At a command line type "ftp" (without the " ") then return. You will see an ftp prompt like this:
ftp]
Open your session with the following format. Of course "your_isp" is literally your ISP.
ftp] open ftp.your_isp.com

| Q-342 | What is the default subnet mask for the IP address 23.255.255.101?
|
|---|
C | 255.0.0.0 | Explanation | 255.0.0.0
The IP address 23.255.255.101 is a class A address because its first byte falls between 1 and 126. Therefore, the default subnet mask is 255.0.0.0.
A class B address would use a subnet mask of 255.255.0.0.
A class C address would use a subnet mask of 255.255.255.0.
255.255.255.255 is not a valid subnet mask. Class D and E addresses require no subnet masks.
|
| Q-343 | You can ping localhost and your own IP address, but you cannot ping your default gateway's IP address. What is wrong?
|
|---|
C | Wrong subnet mask is being used | Explanation | Wrong subnet mask is being used
PING is used to verify a connection between your computer and remote host. You can ping a host using its IP address or its host name. If you can ping a host by IP address but can't by its name then you have a problem with name resolution. Most likely the subnet mask, which identifies which network you are on, is incorrect.
In the scenario listed you can PING yourself therefore the NIC is alright. If you can ping a host by IP address but can't by its name then you have a problem with name resolution. But there is no evidence that the DNS server is down or that there is network congestion |
| Q-344 | If you have a problem receiving email, what should you check?
|
|---|
A | POP3 server | Explanation | POP3 server
A Post Office Protocol server is where you pick up your mail. Just think of a real post office. SMTP stands for Simple Mail Transfer Protocol but if you are haveing trouble keeping POP and SMTP straight just imagine that the "S" in SMTP stands for "send". |
| Q-345 | You want to configure a new client computer to connect to other computers in your Windows NT 4 LAN. Your LAN is not connected to the Internet, and it is not necessary for your users to connect to the Internet or to any computers outside the LAN. Which of the following must you configure? |
|---|
A | IP address and subnet mask | Explanation | IP address and subnet mask
An IP address is needed for the computer to communicate with others in the network. A subnet mask is needed to identify the network name and the host name within the IP address.
A default gateway is not needed, because a default gateway is used to send data to computers outside the LAN, and no such connection is needed in this case. DNS is used to resolve an IP address to a fully qualified domain name. Because you are not connecting to other domains, DNS is not necessary.
|
| Q-346 | What type of DNS entry is used to identify the mail server for a domain?
|
|---|
C | MX | Explanation | MX
MX, or Mail Exchange, record contains information of what email server processes email for the domain. |
| Q-347 | Which of the following IP addresses is invalid?
|
|---|
B | 10.256.33.255 | Explanation | 10.256.33.255
Each field in an IP address must have a value ranging from 0 to 255. The network portion or host portion can contain a 0 or 255 but the network or host portion cannot be all 0s or 255s. The address 10.256.33.255 contains an invalid value (256) in the second byte.

|
| Q-351 | Which device on your segment processes all packets destined for a remote network? |
|---|
A | Default gateway | Explanation | Default Gateway
The Default Gateway is a router that determines where to send packets that are addressed to destinations outside the local segment.
A hub doesn't do any processing.
A Bridge passes packets that aren't addressed to the local network but doesn't process or "route" them to a specific destination.
A switch is a special type of intelligent hub that provides virtual circuits between devices to decrease collisions. |
| Q-352 | How does HTTP1.1 provide "best effort" in transferring data?
|
|---|
D | It supports persistent connections.
| Explanation | It supports persistent connections
Unlike HTTP1.0, HTTP1.1 keeps the port 80 connection open by default after the server has responded to the request from the browser. This enables the browser to make further requests without having to establish a new connection for each request. |
| Q-353 | Which two TCP/IP utilities are the most similar in function?
|
|---|
A | PING | B | TRACERT | C | FTP | D | ARP | Ans | ab | Explanation | PING and TRACERT
TRACERT will display a report that lists all routers and networks that the packet must travel to get to ist destination and the time in milliseconds that packet takes to travel between routers. This is useful when trying to find a bottleneck in your network.
PING is used to verify the connection between your computer and remote host. You can ping a host using its IP address or its host name. |

|
|---|
A | Ping | B | Trace | C | Verify | D | Test IP | E | Echo IP | F | Config IP | Ans | ab | Explanation | Ping
Trace
Ping sends and receives ICMP echo messages to verify connectivity.
Trace (or Traceroute or Tracert) sends series of ICMP echos with increasing TTL values to verify the current route to a host. |
| Q-357 | Which TCP/IP protocol is the primary protocol used to transfer text and binary files on the Internet? |
|---|
D | FTP | Explanation | FTP
FTP or File Transfer Protocol is a client-server protocol that allows a user on one computer to transfer files to and from another computer over a TCP/IP network. Also the client program the user executes to transfer files. Two FTP commands are PUT and GET. PUT is used to send the file from a client to a server (MPUT for multiple files). GET is used to initiate a transfer of file from the server to the client (MGET for multiple files). All FTP servers require a client to have a valid account and a password to access the files. Most FTP sites on the Internet are configured to use "anonymous" access. That is why you are not prompted for user ID and Password when accessing most FTP sites. FTP uses TCP as a delivery protocol. |
| Q-358 | What are the generic paths of a network layer address?
|
|---|
C | A network number and host number | Explanation | A network number and host number
An IP address consists of two parts, one identifying the network and one identifying the host. The Class of the address determines which part is the network address and which part is the host address. |
| Q-359 | Which protocol does TFTP use as a delivery protocol?
|
|---|
A | UDP | Explanation | UDP
TFTP (Trivial File Transfer Protocol) is a stripped down version of FTP. TFPT is a connectionless protocol and TFTP uses UDP as a delivery protocol. |
| Q-360 | What is the result of using a hierarchial addressing frame work? |
|---|
A | Increased availability of addresses. | Explanation | Increased availability of addresses.
This is a pretty easy concept so don't think too hard. If everyone only had a first name (i.e. John, Mary, Pete, etc.) pretty soon we would run out of names. But if we give people second names (John Doe, John Smith, John Black, etc. Mary Jones, Mary White, ...well you get my drift) we increase the availability of names. |
| Q-361 | What is an advantage of using a connectionless protocol such as UDP?
|
|---|
C | Packets are not acknowledged. This reduces overhead traffic. | Explanation | Packets are not acknowledged. This reduces overhead traffic.
Bandwidth is used more efficiently because network resources are not allocated bandwidth that they are not going to use. Also, since packets are not acknowledged, overhead is reduced. |
| Q-362 | Choose a connection type protocol (not connection-less). |
|---|
A | TCP | Explanation | TCP
Transmission Control Protocol is the most common transport layer protocol used on Ethernet and the Internet. It was developed by DARPA. TCP is built on top of the Internet Protocol (IP) and is nearly always seen in the combination TCP/IP (TCP over IP). It adds reliable communication, flow-control, multiplexing and connection-oriented communication.
The other protocols are connectionless. |
| Q-363 | What can a virus infect? (Choose two.) |
|---|
A | Gateway | B | Router | C | Network Card | D | Hub | Ans | AB | Explanation | Router and Gateway
A gateway usually is a router. Routers use software to intelligently forward Internet traffic to ist destination. It can become infected by a virus. Hubs and NICs cannot become infected with a virus. |
| Q-364 | E-mail, FTP services, and Telnet work at which OSI layer? |
|---|
A | Application | Explanation | Application
E-mail, FTP services, and Telnet all operate at the Application layer. The OSI has seven different layers, which are divided into two groups. The top three layers define how the applications within the end stations will communicate with each other and with users. The bottom four layers define how data is transmitted end-to-end. The layers are:
Application
Presentation
Session
Transport
Network
Data Link
Physical
|
| Q-365 | What OSI layer integrates logical addressing? |
|---|
A | network | Explanation | Network
The network layer defines logical addressing and routing as a means to deliver data across an entire network. IP and IPX are two examples of network layer protocols.
|
| Q-366 | What layer of the OSI model controls communication between devices? |
|---|
A | session | Explanation | session
The Session layer is responsible for setting up, managing, and then tearing down sessions between Presentation layer entities. The Session layer also provides dialog control between devices. It coordinates communication between systems and organizes communication in simplex, half-duplex, and full-duplex. |
| Q-367 | From bottom up of the OSI reference model, which layer is the Network layer? |
|---|
A | Layer 3 | Explanation | Layer 3
Always start at the physical layer as the first layer.
When networks first came into being, computers could typically communicate only with computers from the same manufacturer. For example, companies ran either a complete DECnet or an IBM network - never both together. In the late 1970s, the OSI (Open Systems Interconnection) model was created by the International Organization for Standardization (ISO) to break this barrier. The OSI model was meant to help vendors create interoperable network devices. |
| Q-368 | Which layer of the OSI model is responsible for placing the signal on the cable? |
|---|
A | Physical | Explanation | Physical
The cable always refers to the Physical layer.
The OSI model is the primary architectural model for networks. It describes how data and network information are communicated from applications on one computer, through the network media, to an application on another computer. The OSI reference model breaks this approach into seven layers. The Physical layer is counted as the first layer.
|
| Q-369 | The two sublayers of the IEEE Data Link Layer are which of the following?
|
|---|
C | Logical Link Control and Media Access Control | Explanation | Logical Link Control and Media Access Control
The IEEE Data Link layer has two sublayers:
Media Access Control (MAC) 802.3 defines how packets are placed on the media. Contention media access is first come, first served access where everyone shares the same bandwidth. Physical addressing is defined here, as well as logical topologies. Logical topology is the signal path through a physical topology. Line discipline, error notification, ordered delivery of frames, and optional flow control can also be used at this sublayer.
Logical Link Control (LLC) 802.2 sublayer is responsible for identifying Network layer protocols and then encapsulating them. An LLC header tells the Data Link layer what to do with a packet once a frame is received. The LLC can also provide flow control and sequencing of control bits.
|
| Q-370 | Which of the following OSI layers determines which route data packets should take by evaluating network conditions and priority of service? |
|---|
A | Network layer | Explanation | Network
The Network layer is responsible for routing the data packets to their correct destination by the best available path. Routers operate at the Network layer.
The Transport layer provides for reliable and properly sequenced transfer of data.
The Data Link layer is responsible for packaging data into frames and providing an error free "Link" between computers. Bridges operate at the Data Link layer.
The Session layer handles the opening, and closing of a session between computers.
|
| Q-371 | Which layer listed manages access to the Network layer? |
|---|
A | Datalink - LLC Sublayer | Explanation | Datalink - LLC Sublayer
Logical Link Control: Defined by the IEEE, the higher of two Data-Link layer sublayers. LLC is responsible for error detection (but not correction), flow control, framing, and software-sublayer addressing. LLC is described in IEEE 802.2. Think MAC is closer to lower hardware (Media) and LLC is closer to the more intelligent upper layers (Logical). |
| Q-372 | What layer of the OSI model does a bridge operate in? |
|---|
A | Data Link | Explanation | Data Link
Bridges operate in the Data Link layer and are used to segment the LAN. While Bridges create multiple "collision" domains, all bridged segments are still on the same 'broadcast" domain. The reason being that they pass broadcast packets to other connected domains.
Bridges do not help to reduce broadcast storms. They are able to pass broadcasts out every port.
|
| Q-373 | Which layer is responsible for providing mechanisms for multiplexing upper-layer application, session establishment, and tear down of virtual circuits?
|
|---|
E | Transport | Explanation | Transport
The transport layer is responsible for reliable network communication between end nodes. The layers are:
Application
Presentation
Session
Transport
Network
Data Link
Physical
Sometimes a handy memnonic device used to remember the layers is to remember the phrase: All People Seem To Need Data Processing. The first letters of each word correspond to the OSI layers.
|
| Q-374 | Which of the following devices works at the Application layer of the OSI model? |
|---|
A | Gateway | Explanation | Gateway
A Gateway works at the Application layer and other upper layers of the OSI model.
A Bridge operates at the Data Link layer.
A Repeater operates at the Physical layer.
A Brouter operates at both the Network and Data Link layers of the OSI model.
|
| Q-375 | What was the key reason for creating the International Organization for Standardization that released the OSI model?
|
|---|
B | Different vendor's networks could work with each other. | Explanation | Different vendor's networks could work with each other.
The OSI reference model was created to help facilitate data transfer between network nodes. A major function of the OSI specifications is to assist in data transfer between different kinds of hosts. For instance one vendor's LLC sublayer could communicate with a different vendor's LLC sublayer even though they were using different Operating Systems and protocols. The OSI is a set of guidelines that application developers can use to create applications, networking standards and devices that run on a network. |
| Q-376 | What layer of the OSI model ensures packets are delivered error free, in sequence, without lost or missing packets? |
|---|
A | Transport | Explanation | Transport
The Transport layer provides for reliable and properly sequenced transfer of data. A key word here is "sequenced". The Transport layer can re-sequence out of order packets.
The Network layer is responsible for routing the data packets to their correct destination by the best available path. Routers operate at the Network layer.
The Data Link layer is responsible for packaging data into frames and providing an error free "Link" between computers. Bridges operate at the Data Link layer.
The Session layer handles the opening, and closing of a session between computers.

| Q-385 | How does the following code help copyright your page?
[SCRIPT TYPE="text/javascript"]
[!--
if (top != self)
top.location=self.document.location;
//--]
[/SCRIPT]
|
|---|
A | Will not allow frame to be displayed in other web pages. | Explanation | Will not allow frame to be displayed in other web pages.
Frames allow you to combine different web pages together into one window, even if all of those pages aren't yours and weren't intended to be framed. This script checks to see if the current page is the "top" page. If it is not, it tells the web browser to load the current web page as the top, thus wiping out any frames. Of course, this script won't work with browsers that don't understand scripting, or where scripting is turned off, but the script will work on most browsers, and that makes it a pretty effective deterrent.
