Networking Essentials

Status 70-58

Helo GuyzZz n GirlzZz

My name is Brave. I am one more far from my MCSE. Hope will be over in a decade

or so. Really BrainDump helps you how no one else can do. At least it helped me

a lot. So here is my Brain for you NOVICE chicks.

It didn't seem so scary how I was expecting. Passed with 735. Passing marks

were 553. (Definitely not good, but you know Essentials is essential to pass)

You are warned in the beginning " you will face two sections; (1) one is just

simple question series with 2, 3, 4 or more options as usual and (2) second one

is the most HOT topic, adaptive style."

I personally think that if you are clear with your concepts and studies, its no

more hard to understand what he asks you. In adaptive portion (which is not

mentioned during the questions), you have to select, drag-n-drop or point out

the device/thing about which the question is asked. Nothing else … yap!!

Another thing, now you do not have any chance to Mark, Review or Skip that

question, cuz the your answers is used to serve the next one.

Before you Click START

Before you start the paper I suggest that:

Visit the "Washroom"

Don't panic

Don't' worry or scare (its nothing going to KILL you)

Set you chair/seat at comfortable posisiton

Set the DIRECTION of your monitor straight to you

Set the Brightness of the screen not dazzling your eyes

Get a pen & paper to draw something

Calculate the time for EACH question and don't spend even few seconds over

Read the whole question carefully at least twice before deciding any answer

after you START the paper (even you know the exact answer)

If getting confuse, try to ISOLATE the answer, and think why you're ignoring

others

And say THANK YOU BRAVE MAN once

Although all this doesn't concern directly the paper but still you will find it

more easier and more comfortable. Here is my contribution and some explanation

where possible.

(Remember!!! Neither ONLY my Braindump is enough nor whole my answers, Unno I

got 735 NOT the whole 1000. So still try to confirm by yourselves. ( a

suggestion )

my answers are denoted by star (*)

Another thing. In paper, (almost) in every question you will see a table

showing the whole configuration of the network; like, protocols, connecting

devices, media access method, topology, # wks, #srv, and other. Cuz this is

common so it will not be explained here.

==========================================================

1) you have a network with 10 workstations, all windows NT wks. You want to

implement access control os users over some directries.

a) user level permissions *

b) share level permission

cuz NT wks, supports user level permssions on ntfs.

==========================================================

2) you have 2 LANs, one using ethernet and other using token ring. Both the

lans are using NetBeui and Nwlink, You want to connect both the LANs and still

want to use the BOTH protocols.

a) REPEATER

b) BRIDGE *

c) ROUTER

d) GATEWAY

Cuz router doesn't support netbui and you want both the protocols. Gateway is

for protocol translation.

==========================================================

3) in your ethernet bus network, some clients, "some time" can NOT connect with

the server. (an exhibit showing you the network and its configuration) what

would you re-cofigure.

a) termintors

b) ground

c) cable break

d) reinstallation of client software *

e) change with 25 ohm terminator

the figure showed, that you have cable UNBREAKED, both ends terminated with 50

ohm & both grounded, so the last option is D

==========================================================

4) you have 10 NT server, 700 NT client computers. You want to segment the

network with routers. What protocols can you use.

a) DLC

b) NETBIEU

c) NWLINK/IPX/SPX *

d) APPLETALK

e) TCP/IP *

NT supports only these ROUTEABLE protocols

==========================================================

5) your network has 8 NT servers. And 300 NT clients. Connected with routers

and bridges. You r going to add more 300. User complain network lagging. What

to do.

a) disable bridging on bridges

b) replace the protocols with tcp/ip

c) segment the network *

d) (Uhuppsss…..forGot!!!!)

==========================================================

6) you have a network where computers can communicate with each other by IP

address but not with Netbios names. What to check.

a) DNS

b) Routers

c) WINS *

d) Repeaters

e) DHCP

f) Gateways

==========================================================

7) three lans in three buildings 1000 meter apart. Each on 2 floors. Want to

connect (in the lan) computers with a centralized.

Req: faultfree proper networking

Optnal: easy to work and maintain

Easy to add computer in future

Prop: install thinnet.

Produces req and all optional (three/four questions of the same kind)

==========================================================

8) an exihibit, you own a token ring network. Star bus topology. One server

connected with one end in ONE star. Users complain slow network. You observe

that on ONE star where the server exists, clients are transmitting extremely.

You want to DISTRIBUTE the servers responsibility and segment the network.

(this is adaptive question) Solution. Drag the bridge (from left-side column)

and drop between the two STARs. And pick an application server (from the same

place) and add it on the OTHER star.

==========================================================

9) in a network, one computer named CORP-1, DATA a directory on the same server

containing some files of Human Resrc. Dept. the directory shared with the same

name; DATA. A group named HR has change permissions for that folder

\\CORP-1\DATA. No one else except the group has access to that folder. What

kind of access permission will you apply.

a) File level

b) share level

c) user level *

d) hardware

==========================================================

10) you are introducing APPLICATION server to a firm. What should you say.

a) both application and file/print servers can store data *

b) application server processes server side as far as client side application

process *

c) application server gives file/print services

d) (Uhuppsss…..forGot!!!!)

==========================================================

11) secrued delivery on Unreliable medium.

a) X.25 *

b) ISDN

c) ATM

d) T1

==========================================================

12) thre lans want to connect with one headquarter MAINFRME running token ring.

What wan technology works.

a) X.25 *

b) ISDN

c) T1

d) ATM

Cuz x.25 was used to connect mainframe and it uses PAD

==========================================================

13) the mainframe and pcs. Want to connect. What device used.

Ans. Gateways

==========================================================

14) a lady (Uhuppsss…..forGot!!!!) using tcp/ip for 5 years. His dial up

protocol doesn't support automatic IP address. Which protocol.

Ans. SLIP

==========================================================

15)  10 client computer with Win NT workstation. Which  kind of access control

and control access to file and directries on the network?  Choose all that

apply.

a) User  & group  access control  to each shared resources *

b) Supply passwork for each shared resources.

==========================================================

(Uhuppsss…..forGot!!!!)

Transfer Interuppted ....

Error:: The Brain you attemted to connect is going to sleep …

==========================================================
