Subject: Brain Dump 70-058, Microsoft Networking Essentials.

Fantastic Web site! Kudos to all who contributed. This place will save

your buttocks, it saved mine! The only resources I used was the

Microsoft self study kit, their test exam at their web site,

(http://www.microsoft.com/mcp/examinfo/practice.htm),

the brain dumps and practice tests mentioned elsewhere at this site.

This site was by far the best resource other than the book itself.

Generally everyone else’s postings have been quite accurate in stating

what to know.

Many of the questions they warned about did show up. Still nothing

about wireless networks (guess MS still isn’t in the mood to put them

in)

I’ve seen different points of view on how many 28.8 RAS lines you need

to get a T1 (1.544 mbps) line. Some people have a (# of Modems * modem

speed * 100 / 8) to get the combined mbps of the modems. I don’t

understand where the 100/8 comes in. I calculated (# of modems * modem

speed). I did get the does-8-28.8-modems-give-you-1Mbps-speed

question that comes with the three cities scenario. I said 8 RAS modems

wasn’t enough, but using the above formula with the 100/8 part, it is

enough. Anyone got a definitive answer?

One question was a which-layer-of-the-OSI-model-does-X-fit-into and they included a diagram of the seven layers! Why thank-you! (of course, if

you don’t know it anyway you’re probably dead meat but I was bemused)

This wasn’t the first question, of course, it was the forty-somethingth question.

Interesting questions that made me scratch my head:

5 computers networked over a WAN, using NetBeui, TCP/IP, (something

else), they have encryption and compression. What protocol do they use?

(choose one)

-SLIP

-PPP

-DLC

(I know it isn’t SLIP, but what the heck is DLC?)

Which network operating systems have share level accesses? (Choose all

that apply)

-WfW

-Win95

-NT

-NT Server

Which protocol provides file services above the NetBios level?

(lots and lots of choices, I said SMB. Oops, I think)

You have many offices, each with many people running Win95 peer to peer.

High staff turnover. What do you do to increase security? (choose one)

Centralize accts, user-level passwords.

Centralize accts, share-level passwords.

Peer to peer, user-level passwords.

Peer to peer, share level passwords.

(Presumably there are no servers, so does that rule out centralizing

accts?)

What do you use to install a 100Mbps ethernet network? (choose one)

Cat 3 UTP

Cat 5 UTP

Thinnet

FDDI

(I said Cat 5 UTP, but FDDI would work just fine too, so I don’t know

for sure)

I got the network-with-two-ends-of-it-grounded question and had to pick

one corrective action. One said terminate the network properly, the

other said ground the network properly. Hmmm… subtle or what? I chose

"ground." Since I got 100% on troubleshooting I’ll stand firm on this

answer.

Some of the questions I got that others have mentioned:

Which WAN protocol is > 100Mbps? (ATM)

Which WAN protocol is bandwith on demand.(frame relay)

Two(!) questions about the advantages of NDIS/ODI (independent of above protocols)

Person can no-longer connect to server question. (check cable)

Initializing IPX linked computer, doesn’t work, why? (incorrect frame

size)

Reliable connection over unreliable switched network (X.25)

Copying a file from Token-ring LAN to Ethernet LAN takes longer than

reverse (different frame sizes).

Which three names cannot be duplicated in a NetBios network (domain can

be duplicated, I think)

Network card has IRQ 3, what does this interfere with (COM 2) (in my

case the computer in question was a server, but that doesn’t matter)

PC won’t boot off SCSI drive after Network card is put in. (IRQ conflict

w/SCSI device)

Can ping a server by IP address but not by name (server not registered

in WINS?)

Same scenarios with the cities as others have mentioned.

Want to connect to a mainframe w/out loading new software on clients

(gateway)

Want to segment TCP/IP network (routers?)

Win95 and Macs and Unix machines on a LAN with lots of protocols loaded.

Reduce broadcast storms and provide for future expansion.

Which provide guaranteed transfer (connection oriented, not

connectionless)

Phew… brain is fading… maybe I’ll have some flashbacks later but for

now that’s it. Good luck!
