Subject: Networking Essentials 620 not so good
There are questions on the test that are *not* covered in the book. Like adjusting window sizes. Be prepared. Frames to NDIS- Absolutely required to have thorough knowledge of NDIS and ODI, and not just their ability to provide multiple bindings to a single NIC.
There were *several* questions on this on the test I took. I didn't know NDIS as well as I would have liked to for this test. Study it well.
Several of the "multiple multiple choice" questions identified success and failure auditing as something I haven't heard of before.
RAID- several questions on RAID, mostly the diff. between levels 0 and
What is the fastest chepest recovery 20 min or less
raid 5
duplexing
backup?
I was looking for a mirrer Not there
Lots of irqs
Can You turn of the router or the brouter?? part of a some questions
Several questions on protocol mismatch scenarios.
Several questions (wfw3.11 related) on memory problems (or lack of memory) related to NIC drivers.
The multiple multiple choice questions seemed to come in packs of 2, with the scenarios the same, but the proposed solutions slightly different. Be comfortable answering these tough questions.
Know the diff. between a TDR, Protocol Analyzer, and Advanced Cable tester. There were probably five or so questions related.
Know which protocols are routable, which are used by mainframes, and when to turn off the (elusive) bridge function on a brouter. The whole brouter thing really pisses me off, btw.
Try to get an understanding of what MS wants for an answer, not just what is the correct answer. For instance, I have had instances in both the Transcender tests, and the real thing, where they claim that 10baseT is cheaper than 10base2. From my point of view, this is ridiculous, at least initially. The cable's cheaper, you don't need hubs, etc. But, that's not what Microsoft wants to hear so.....This also applies to a lot of the multiple multiple choice questions. Try to get an instinct for what answer they're looking for, rather than what you might think to be the most logical choice. (this is redmond-speak we're dealing with here).
Several questions on Volt-Ohm meter readings. Like if it shows infinity or zero, which component do you need to replace, including figuring out the diff. between readings on different cable types. This stumped me, don't know if I got it right or wrong. But good to know, anyway.
OSI- Know what connectivity devices function at what level of the OSI model. Routers, gateways, bridges, the always lovable brouter, repeaters, etc.
WAN- know the different WAN connectivity devices, what layer of the SI model they work at, what data transmission rate they're capable of, what their general use is, etc. ATM, FDDI, ISDN, T1, T3.
Troubleshooting Apps.- Know them
One question on Mesh topology.
One question on Connectionless v. Connection Oriented communications.
Several of the mulitple multiple choice questions were related to reducing Network Utilization by %50, and proposed scenarios how you would do this.
My test questions were very different from the Transcender test. You really must know this stuff.
Use the deductive method of reasoning. There's usually two or more answers that are ridiculous, then two that are somewhat plausible. Read the questions carefully, and look at specific words to try to gain insight into the reasoning involved.
1. What is purpose of NDIS?
2. What are object of NDIS and ODI?
3. The Client have LPT1, LPT2, FP disk, MOUSE and bla... when install NIC with IRQ 3 it not work.. Why? (They have two questions something like this.)
4. If you want to segment the TCP/IP network (300 client) with 3 segment you will use ....... device?? (Router or Brouter or Bridge or Gateways)
5. If you want to segment the NETBEUI network (300 client) with 3 segment you will use ...... device?? (Router or Brouter or Bridge or Gateways)
6. Which dial-up line can use dynamic IP address (SLIP or PPP)?
7. Which dial-up line can compress data (SLIP or PPP)?
8. Which protocol can route?
9. What device can translate protocol? (Router or Brouter or Gateways or ....)
10. If I want to connect IPX/SPX clinet to IBM Mainframe computer, I use .... device? (Router or Brouter or Gateways or ..........)
