Good hints I've collected: Take the prep quiz (to make sure you understand the testing procedure), but instead, jot down as much of your notes as you can think of on the scratch paper (you get 15 minutes); Mark the scenarios, and do them last; on scratch paper, write breif description of each question, and use them (if you can) to help you later in the test.

I can't remember too much of the test other than the following:

1. You have several 28.8 modems attached to an RAS pool, and need 1.5 Mbps.(This was the primary objective of a scenario question.) The following scenario had 3 t-1 lines connecting 3 cities, with a slow voice line also connecting the 3 cities. Desired: Interconnect the 3 cities with 1.5 Mbps. Optionally,
(a) they should maintain communication if one goes down,
(b) they should maintain 1.5 Mbps if one of the lines goes down.

2. On what layer do SMBs reside?

3. You are building a fault tolerance system on your server. Downtime of 2 hours okay.

4. You need to build a temporary, cheap network. (I chose Bus)

5. Lucy can no longer connect to network. Some of the answers were bad nic on server, faulty terminator, etc. (I chose loose cable)

6. Which media can support 100 Mbps?

7. One question on IRQs.

8. I had two on ODI and NDIS, so know those.

9. Protocol analyzers were everywhere.

10. ATM was there (WAN communication >100 Mbps)

11. You need to install fault tolerance in your server. Cost is a factor. What do you implement? RAID 0, 1, 5, duplexing? I put duplexing. Not sure about this one.

I had none on wireless communication (thank God), and only 4 scenarios total!
