| Some of these questions have faced fierce debate on these forums. Would anyone please give answers from iNet exam's point of view?
I have included my guesses:
1 A. Which technology implements VPNs using IPsec?
or To use Virtual Private Networking (VPN) in conjunction with IPsec, which of the following is used?
A. L2TP
B. PPP
C. SLIP
D. PPTP
Ans= A. But why not PPTP which is mostly used for VPN's?
2. Which network hardware device connects dissimilar network topologies into
an internetwork?
Or
Which device will connect different network topologies together for communication?
A. Gateway
B. Router
C. Bridge
C. Hub
The question does not mention a TCP/IP network, so my guess would be Bridge.
For TCP/IP network, the answer is router.
3. Internet connection that limits bandwidth usage:
A)Network add. Transmission firewall
B)Packet filtering gateway
C)Replication server
D)Proxy server
Would the answer be proxy server. If yes why?
4. Web site to pull info from departmental database:
A)HTTPS
B)DTD
C)Corba
D)Software agents
Ans = Software agents?
5. In order to access a Web site named secure.examnotes.com that uses SSL and requires you to log on. Which URL is correct?
A) https://username@password//secure.examnotes.com
B) https://username password@secure.examnotes.com
C) http://username@password:secure.examnotes.com
D) http://username password/secure.examnotes.com
Is the answer = B
6. Web client application times out when attempting to open a socket to a web server. You should check to see if:
A) the proxy server is down
B) socket is available through the firewall
C) browser cache setting is correct
D) https is not enabled
Ans = A??
7 You want to compare a form entry to a valid list of dates on a Web based form. Which requires the least infrastructure set-up?
A) Relational Database (ODBC)
B) Object-oriented database (JDBC)
C) Javascript
D) XML
Ans = A ?
8. Which is the proper syntax to include a copyright notice in the header of a web page:
A) <COPYRIGHT VALUE="2000, Examnotes">
B) <META NAME="Copyright" CONTENT="2000, Examnotes">
C) Copyright &#copy; 2000 Examnotes
D) <COPYRIGHT ATTRIBUTE="2000, Examnotes">
Ans = B ?
9 A proxy server is connected to the internet via a cable modem and can access the internet. Your users cannot access the internet, the ISP verified that connection was available. What should you do to fix the problem?
1. Reset the cable modem
2. Reconfigure the ftp services on the proxy
3. Restart the client computer
Ans = 2 If correct, why?
10 .How would you log onto an ftp site on a web page that requires a username and password?
A. username @Password:ftp.xxxxx.xxx
B. username:Password:ftp.xxxxx.xxx
C. username:Password@ftp.xxxx.xxx
D. Username@Password@ftp.xxxx.xxx
Ans = ??
11. Legacy system with schedule information in structured text file--use what to publish to web site?00
A)DHTML
B)?
C)PERL
D)Inline HTML
Saw this question somewhere. Any body has any idea of what it is about?
Thanks

| Adil, you ask some tough questions. I'm not sure I'm answering them sufficiently since you said you'd like the answers from i-Net's point of view. But here goes an attempt...
1. L2TP I found this from an rfc (Request for Comments) site: "http://www.landfield.com/rfcs/rfc2661.html
9.4 L2TP and IPsec
When running over IP, IPsec provides packet-level security via ESP
and/or AH. All L2TP control and data packets for a particular tunnel
appear as homogeneous UDP/IP data packets to the IPsec system.
In addition to IP transport security, IPsec defines a mode of
operation that allows tunneling of IP packets. The packet level
encryption and authentication provided by IPsec tunnel mode and that
provided by L2TP secured with IPsec provide an equivalent level of
security for these requirements.
IPsec also defines access control features that are required of a
compliant IPsec implementation. These features allow filtering of
packets based upon network and transport layer characteristics such
as IP address, ports, etc. In the L2TP tunneling model, analogous
filtering is logically performed at the PPP layer or network layer
above L2TP. These network layer access control features may be
handled at the LNS via vendor-specific authorization features based
upon the authenticated PPP user, or at the network layer itself by
using IPsec transport mode end-to-end between the communicating
hosts. The requirements for access control mechanisms are not a part
of the L2TP specification and as such are outside the scope of this
document."
 That's a mouthful. The basic def. I heard was L2TP implements VPN using IP Security.
2. That's what a bridge does. I've seen study aides say router because it is an internet focused test. I'd stick with router as the answer though.
3. A proxy server limits bandwith because it looks at the request first. If it the request cached it delivers the cached copy. Therefore, there's no need to use the bandwith to complete the request from the web server; it can be completed "locally".
4. Software Agents - no reason other than process of elimination. I can't find info on s/w agents and the other choices don't make sense to me based on the question.
5. B. That is the convention.
6. A. If the browser goes through a proxy server and it's down; it won't make it beyond the proxy.
7. A. Relational DBs are the easiest to setup.
8. B. It'll will look a little different on the test. It won't ask for the code for the "< >" (< and >). It will show <meta... ...name">. Extra note: the copyright symbol is "©"
9. A. reseat the cable modem. I hear cable modems need to be reseated as the 1st troubleshooting step - common problem.
10. C. C. username:Password@ftp.xxxx.xxx
convention.
11. No idea.
These are some tougher questions. If they are you only ones you have - take the test. It's very straightfoward. Good luck!!! | |

| DFox: Actually, I was just wondering if you recently took network+ or iNetplus because you did good job in handling the 10 questions.
Yes, I will be taking this exam in few days.
Well, here are few leftovers:
1. You want to put background music on a web page. Which of these are the best way to do this?
1. Embed
2. BgSound
3. RealMedia plugin
4. AVI
??
2. Which is an invalid coding type for email?
A) Base64
B) Uuencode
C) Zip
D) BinHex
Zip?? Thru process of elimination
3 An ISP has assigned you a class C network address and a valid subnet mask. What should you use to connect to the Internet?
Gateway
Router
I would say Router which can also be configured as a Gateway.
4 In MIME Header, line 1 shows the MIME version, what is in line 2?
A)Size
B)Author
C)Parts format and body parts
D)Content Type
E) Version No.
Could anyone correct me:
Line 1 = MIME version
Line 2= Content Type | |

| Ok, I researched the following answers to be correct:
1. You want to put background music on a web page. Which of these are the best way to do this?
1. Embed
2. BgSound
3. RealMedia plugin
4. AVI
Ans = Embed and BgSound
2. Which is an invalid coding type for email?
A) Base64
B) Uuencode
C) Zip
D) BinHex
Ans = Base64
4. In MIME Header, line 1 shows the MIME version, what is in line 2?

E) Version No.
Answer is as follows:
Line 1 = MIME version
Line 2= Content Type | |

| I took the exam 2/2/01. Looks like you answered your other questions. My advice is to find the practice exams mentioned in this forum. They were very similar to the real exam. I also spent a good deal of time researching the answers (correct and incorrect) at webopedia.com and whatis.com. Good luck in your studies! |
