Subject: Net Essentials brain dump

Took the NET ESSENTIALS exam on June 26th, PASSED with a 948.

 

EXHIBIT questions:

mesh network displayed (know what a mesh looks like)

3 offices: T1 ----- TI -------T1, one link goes down.

Can everyone still communicate, and at 1 Mbps?

 

2 offices: L.A. T1 à Chicago, Chicago T1 à NY

Can everyone still communicate, and at 1 Mbps?

 

Bus network, Terminated on both ends (50 ohms), Grounded on one end.

Cable = 0 ohms end to end

à replace cable

 

 

PARAGRAPH questions:

[3] questions - similar scenarios wanting - data protection (raid

levels…), hardware protection (UPS), backing up, virus protection,

tracking logons (auditing), security, ect

 

[3] questions, all very similar, Network performance down, need to

cut efficiency 50%

(they gave answers like - replacing cable, NICs, hubs…..)

to all of these questions I answered [d] - does not fullfill requirement

 

[2] questions - similar - lists stuff about internal LAN and other

company's LANs, although question really only pertains to local LAN.

Asks about setting up NETBIOS names for server and all clients, and asks

when eventually connected to the other LANs, with this scheme still be

active?? something like that

Proposed items included giving HEX #s for computer names, the other

question said numbers & characters up to 15. And then some security

questions. They're easy questions, but they just through all this

mumbo-jumbo stuff in to confuse you.

 

 

DEFINITION questions:

gateway

router

brouter

crosstalk

other easy stuff…. (cable type & components)

UNC à computer name \ share name

connection oriented = assured delivery

RG 58 A/U - is NOT compatable to RG 58 U

remote computer dial-up w/ TPC/IP, what protocols can be used? à PPP,

SLIP

what is replacing telephone lines à ISDN

client/server question

[2] NDIS/ODI questions

[2] IRQ conflict questions

running. NIC initialized fine"

à know wrong frame type, wrong transciever type,

 

Unix & DOS clients connected to NT server. 1 more server added, why

can UNIX client communicate?

3 - network tool questions (I think all my answers were Protocol

analyzers)

 

 

Good luck everyone!

I couldn't have passed without those Transender practice exams, and

this Braindump site.

There were many things I would of never picked up from just the Net

Essentials Self-paced book.
