Subject: helpful for my 70-058 preparation (#1)
Prelude to Network Essentials brain dump:
I took the Network Essentials Exam (12/22/97), my first in the series of six, after several weeks sporadic preparation, and one week of cramming (review). I read all chapters and did exercises (even the tedious ones) from the Sybex Network Essentials Study Guide. The three accompanying video tapes I watched and fell asleep to <g> because I’ve done network support for 8+ years (tapes recommended only for beginners). I downloaded a few sample tests (asm_1+asm_2+asm_3 and mcsepep from www.microsoft, Transcender’s, Self Test Software’s version M2.12, OmniWorld’s version 1.1 "Masters of MCSE" MCP 70-058 Networking Essentials). I discovered this BrainDump site about a week ago, and read a lot there. The high passing score on this test (793) caused much studying ... I missed 4 out of 58 questions (if you miss more than 12 questions, you don’t pass ... yikes!).
UPSs and Power Failures at the Test Center:
At www.slspro.com they have some info and terms about the test centers.
Yes, they do have a UPS on the server that administers the test. Yes, the
PC that gave me my test did not have a UPS, and the power flickered off,
rebooting my PC! "Aghhh!", screams three testees. Proctor runs
in assuring everyone it is all right. I ask "is this part of the test
... do I have to fix something?". No. PC boots up, log back in with
SSN, and it takes us all back to the last place we were in the test.
Helpful Technique for the Situation Questions:
Network Essentials Brain Dump:
1. Select all that _only_ use a password on a share resource:
[x] Windows for Workgroups
[x] Windows 95
[ ] Windows NT wksta
[ ] Windows NT server
2. Select all where do you _can_ use the same NETBIOS name:
[x] workgroup name
[ ] computer name
[x] domain name
[x] sharename
3. You have connected a Token Ring Network (4MBit/s) and an Ethernet Network. Copying from Token Ring to Ethernet for a 5MB File takes 30 seconds. Copying from Ethernet to Token Ring takes 2Minutes. Why ?
[x] The token-ring network is slower (my guess) (sorry: wrong, different frame sizes...)
4. Using NetBEUI and NWLink IPX, want to connect the two segments, and still use both protocols
[ ] repeater
[x] bridge
[ ] router
[ ] gateway
(hint: NetBEUI is not routable)
5. Which WAN connection will work over 100Mbs?
[ ] T-1
[ ] frame relay
[ ] X.25
[x] ATM
6. Anne's computer can access the network, but everybody else can …
[x] network connection at Ann's computer.
7. A server which performs processing power for client computers is …
[ ] a file server
[x] a application server
Sorry that's all I recall, obviously my brain was dumped on the exam!
