i'm so lucky that i have only one Solution about 50% usage, and frankly i don't konw the answer, i select "don't meet the required", maybe wrong.

Something about TCP/IP, you should know a little about it...

These braindump is the summary which i used, 90% are right, and 80% of exam in it. read it more carefully and know why is this answer or not. if you meet a question that you haven't seen, don't worry, you can answer it by yourself. if you lost this one, never mind, do better at next one. Coz you can lose about 10 questions.

A: met the required and only one of the desired.

¡¡

Q: same scinario, same required and desired results. Solutions: reduce the frame size and increase TCP windows size.

A: not meet the required as more frames will cause more collisions and only slowdown the network.

¡¡

I also had a question about a company having Cat 3 UTP cabling and they wanted 50% less network congestion while keeping the network activity at the same level. The selections included:

1. Change the frame size from 1,547 (or something like that) to 576

^^^^^ This would actually increase the network activity since packets are smaller

2. Change from UTP Cat 3 to Cat 5 and put in 100BASET and segment using routers.

^^^^^^^^ I chose this one. Even without the segmentation this would provide the required result because you are going from 10mbps to 100mbps.

1 56k modem. Users complaining about slow performance. Server already maximized. What can you do to speed up the network?

You have a main office and four other two-story offices in a different location 20 miles away. The computers in each building will have distances with a max distance of 140 meters and you want to implement 10BaseT

Requirements: Connect all five offices to network with each other

Optional Results: You should use the least amount of cabling as possible

Solution should be as cheap as possible

Solution:

Connect each floor of office using hubs and one active hub for each floor. Connect the two distant offices with fiber optics. Imlement RAID with stripe set. Implement Nightly-Tape backup. Implement a bunch of other shit that has nothing to do with connectivity.

Now the answer to this wasn't clear to me, because, first of all, I think for a distance of 20 miles, you'd need a concentrator, but other than that, if it worked, you wouldn't have the "cheap as possible" solution, because although the connectivity hardware was the cheapest possible, a bunch of other stuff was implemented that wasn't necessary for the situation.
