| First of all props to Examnotes on this web-site, you guys have done well!!
Now, you have to love those CompTIA test. So much more easier than Microsofts. You either no the answer or you don't, no thinking involved!
Anyway here's a few questions for u all:
1. VeriSign is an example of what?: I said Certicate authority
2. 1000 of ICMP reply request to a site is?
I said ping flooding
3. Type of encryption uses a pair of keys?
I said secure state level
4. A protocol such as HTTP that uses a "best effort" delivery strategy is called a?
(I really dont get this question)Your choices are
a. connectionless
b. connection-oriented
c. stateful
b. burstmode
(HELP ME OUT ON THIS ONE)-I said a. I dont know what c and b even are?
5. DNS entry to identify a host is? A record
6. B class address has how many host? If you dont know then dont bother taking the test!!
7. Heres a dumb question? You have a 4 hour long multimedia presentation and u want to put it on the web. what should u use?
a. QTVR
b. Real media
c. DVD
d. MP3
(well i choose b) u tell me what u think?
8. Another dumb one. A customer wants to implement a contest on her web site to give away product samples. Which technology best suited for this?
a. MP3
b. shockwave
c. Flash
d. DVD
HELP me out here? not a or d. and whats the difference between shockwave and Flash? I thought Flash was a type of shockwave?
9. Your moving from the US to far East. Must comply with encryption technology?
a. international patch for browser
b. international plug in for browser
c. international version of browser
d. international MIME type
Im not sure?
If your an MCSE this test is cake.
Also examnotes study guide is great, use it and you'll pass!!
MCSE, MCP+I, MCT, NET+, iNET+, MOUS
(not that u care

| Hmmm- what do you guys say about these answers? any you would disagree with?
These are the only halfway hard questions on the test. So you ALL should be able to pass with the answers to these. | |
|
| Here's my two cents. (preceded with *)
1. VeriSign is an example of what?
*I agree, Certificate Authority.
From Verisign site:
http://home.netscape.com/solutions/...s/verisign.html
"VeriSign runs its own commercial certificate authority (CA), which issues millions of digital certificates to individuals and businesses for secure email communications and secure web site access. The company also provides organizations with the ability to build and maintain their own public key infrastructure to issue digital certificates to employees, partners and customers for secure communications and commerce."
2. 1000 of ICMP reply request to a site is?
*Looks like you got it right.
From NetworkICE.com"
http://advice.networkice.com/Advice...ood/default.htm
"Attacker simply sends a huge number of "ICMP Echo Requests" to the victim. This is an easy attack because many ping utilities support this operation, and the hacker doesn't need much knowledge. However, since it tends to overload network links, it is usually as detrimental to the attacker as to the victim, unless the attacker has a MUCH faster link that the victim
If you are being flooded at full Ethernet speeds, filtering the incoming packets will help. If you have a slow, dialup connection, there isn't much you can do except hang-up and reconnect with a different IP address.
3. Type of encryption uses a pair of keys?
*Since we don't know the other choices, it's hard to say on this one. If Public Key or PGP were choices, I would go with one of them.
From webopedia: http://webopedia.internet.com/TERM/...od_Privacy.html
"A technique for encrypting messages developed by Philip Zimmerman. 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 disseminate 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."
4. A protocol such as HTTP that uses a "best effort" delivery strategy is called a?
(I really dont get this question)Your choices are
a. connectionless
b. connection-oriented
c. stateful
b. burstmode
*This one has me puzzled too. For the Network+ exam, CompTIA considers HTTP to be connection-oriented. On the other hand, "Best Effort Delivery" seems to refer to IP and UDP, which are both connection-less.
HTTP is also considered a "stateless" protocol, because it depends on cookies to keep track of a user's preferences. For that reason, I would eliminate "stateful".
I would eliminate burstmode, because it doesn't seem to fit with HTTP.
So the question seems to be asking if HTTP is connection-oriented or not. HTTP is an Application layer protocol that uses TCP as a transport mechanism. Since TCP is connection-oriented, this indirectly results in a connection-oriented session.
There is some food for thought, but I really don't understand the question either.
5. DNS entry to identify a host is? A record
*Again, I agree with you on this one.
6. B class address has how many host? If you dont know then dont bother taking the test!!
*Let's say: 65,534
7. Heres a dumb question? You have a 4 hour long multimedia presentation and u want to put it on the web. what should u use?
a. QTVR
b. Real media
c. DVD
d. MP3
(well i choose b) u tell me what u think?
*I agree
8. Another dumb one. A customer wants to implement a contest on her web site to give away product samples. Which technology best suited for this?
a. MP3
b. shockwave
c. Flash
d. DVD
HELP me out here? not a or d. and whats the difference between shockwave and Flash? I thought Flash was a type of shockwave?
*Don't have a clue on this one.
9. Your moving from the US to far East. Must comply with encryption technology?
a. international patch for browser
b. international plug in for browser
c. international version of browser
d. international MIME type
Im not sure?
*I would go with browser version.
Sybex covers this one on page 313 of their iNET+ Study Guide.
"If you've ever downloaded a Web browser in the US, you were probably offered a choice of key lengths. You could download the 40 bit version without any questions, but you had to make a lot of statements about your citizenship for a browser that could handle 128 bit encryption."
Hope some else can add some more to this,
BobR

| Verisign is a CA for SET transactions.
Ping uses ICMP packets.
Whas it Asynchronous/Asymmetrical Encryption?
Connectionless?
Address record identifies a host @ IP address.
Approx 64000 (65534 is accurate. Remember 2^N-2)
Real media is the way to go, because I can just see a user having to wait for that 4 hours of video to download to their machine without buffering playback! hah hah hah!!!
Shockwave is good for online games. Flash is Vector graphics and troublesome. Shockwave uses Sound, etc. and is interactive.
An International patch for browser would be best. Installing a new version of the browser complicates things , where as a patch to the encryption level will not alter settings, cookies, and bookmarks, etc.
What is CSS again? Cascading Style Sheet or Commercially Secured Server? What if you hypothetically get both answers for that question with no bias toward Internet or Web (HTML)?
I've heard people say "just remember Cascading Style Sheet"... Is this why?

| JackN,
I'm glad you posted your comments for these questions. I would have answered Real Media for the four hour presentation and also would have gone with shockwave for the contest, but only because I seen them given as the answers so many times.
It looks like the Real Media choice is based on the buffering feature. Question: does shockwave not have the buffering feature? Also, can you offer more details as to why shockwave would be a better choice for the contest? I have looked far and wide for explanations for these two questions and what you said makes more sense than any thing I have found. I'm still curious about the interactive feature of shockwave.
Thanks,
BobR | |

| The differences between Flash and Shockwave are really confusing. Shockwave is created for the Shockwave plug-in but is authored in Macromedia's Director. Flash is created for the Flash plug-in but is authored in Macromedia's Flash. For some types of content, they are equals. To make things more complicated Director has a Flash playback. Director is bitmap-oriented whereas Flash is more vector-oriented. You can find more difference if you visit: http://hotwired.lycos.com/webmonkey. Look under multimedia: Director vs. Flash. let me know what you guys/gals think.
