Hey gang, I finally blew my first test. I have already passed Workstation, Server, TCP/IP and thought Essentials would be a breeze, but missed it my 2 questions. I probably went back and changed too many of my answers, I probably had it passed if I had not second guessed myself. Here are a few questions, some of which I could not even begin to answer.  First, I got the dreaded 16 RAS connection scenario with all kinds of interesting side options. I had no idea, so probably got it wrong.

What is an example of a server/client network?

I eliminated two of the choices right off the back, but the other two were

A - Any computer can access resources on any other computer.

B - Any computer on the network can act as a client and a server.

Here is a tough one:

What tool do you use to measure the available bandwith on a cable?

A. Volt Meter

B. Performance Monitor

C. Protocal Analyzer

D. TDR

What protocol do you use to network 5 Windows 95 computers?

A. NW Link IPX

B. XNS

C. DLC

D. NFS

Packet switching connection service that provides reliable delivery in an unreliable environment.

A. X.25

B. frame relay

C. ATM

D. ISDN

Know routers, bridges, repeaters, brouters, etc...

Know the protocols and which fit where in the OSI

Know which protocols are Network and which are Transport

Which WAN link can provide transmissions at any available speed?

A. T1

B. X.25

C. Frame relay

D. ATM

What must you ensure that a NetBIOS name does not duplicate?

Choose three

A. Another computer name

B. Another domain name

C. Another workgroup name

D. Another share name

Know your RAID levels and which ones are Fault Tolerance

You need to install a 100 Mbps network and you have a plenum space of half a meter or so, keep the cost to a minimum,which one should you choose?

A. Coaxial

B. Fiber Optic

C. UTP

D. STP

This question did not mention anything about fire safety, plenum space or sharing conduit space with phone lines. Answer C seemed the best.

You need to connect an Ethernet network, Token Ring network and a Fiber Optic network by a device that provides flow control, Broadcast management and multiple communication paths?

A. Gateway

B. Router

C. Repeater

D. Brouter

Since there is no mention of multiple protocols, a brouter does not seem necessary. The need for multiple communication paths answers this one.

If any of you got the scenario question about decreasing network utilization by changing frame sizes, changing window sizes, switching to all TCP, etc.. I would be interested in your viewpoint on it. I was more confused than ever.

Also, the scenario with the three cities, having two T1 lines with parallel 9,600 baud lines. The whole thing seemed very weak, I chose that it did not work at all.

After I take the test again next week, I will try to put some more questions on here. Thanks to all of you for the information given here. I am not sure if I am allowed to put my Email address here, but I really an curious about how to figure out how to measure how much bandwith is available on a cable.

My email address is [email protected]. If they do not allow any email addresses, maybe someone can put a posting on here and let all of us know.
