3.) What is an IP address

A network number and a host number (M.A)

A domain name and host name

A domain name and node name

One other

What you do if frame-relay inverse arp wouldn’t work.

Static map (M.A)

Static route

define an IP address locally

Something of DHCP can’t remeber

5.) enable IGRP with AS 200

Router (config)# router igrp 200 (M.A)

Router (config)# router igrp

Router (config)# enable igrp 200

Router # router igrp 200

6.) What is the bandwidth of all ISDN channels

144k (M.A)

128k

16k

64k

7.) There was an exhibit which was showing 5 screen displays and they were asking confusingly which group number is having the name of the device which router during setup edit.

Obviously the NVRAM which was in the C group so I type the letter c in the box.

8.) One drag-n-drop of OSI Layer model including the transport, network and data-link layer.

What is the characteristic of isdn DDR. (Don’t remember answers)

What is the characteristic of TCP

Tell two of the five option but don’t remember the options.

What are in the correct order

TCP acknowledges (M.A)

TCP Three way hand shake (M.A)

UDP no acknowledgement and sequencing (M.A)

IP Routing

And two other wrong options.

12.) For distinguishing PVC what is used in frame-relay

DLCI (M.A)

13.) The leased line of 56k is faster then ISDN BRI.

True

False (M.A)

14.) What are the methods of preventing routing loops in Distance Vector Routing protocols.

Route poisoning (M.A)

15.) In the lan of a company it is required that no other department can access the finance department what you install.

Router (M.A)

Switch

Bridge

Hub

Repeater

16.) 172.16.7.160 255.255.255.192 what is the address of the last host.

172.16.7.190 (M.A)

172.16.7.191

172.16.7.254

172.16.7.127

17.) What advantage is offered by LAN segmentation?

Smaller collision domains (MA)

Decreased broadcasts

Three other wrong options

18.) What you type from user exec to go to privileged exec

enable (M.A)

privileged

etc

19.) line console 0 what probably you are going to do.

Change the console password (M.A)

Going to the global configuration mode

Going to assign address on serial port J

Etc.

20.) what is the command to see all the access-lists

Router# show access-lists (M.A)

Router# show access-lists all

Router# show all access-lists

Router# show ip interface

21.) What is the command to see the access-list on the interface serial1.

Router# show ip interface serial1 (M.A)

Etc.

22.) What is the command to see the DLCI and LMI.

Router# show interface serial1 (M.A)

Etc.

23.) How to assign ip address.

Ip address (ip address) (subnetmask)

Etc.

24.) What the address of Novell consist of

network number and mac-address (M.A)

etc.

25.) How the switch work

It see the network layer address and match it from its table and forward packet.

It maintain network and data-link layer address table.

It match the data-link layer address with its table and forward the packet to the destination. (M.A)

Two others

26.) What is the switching type when the switch store the whole frame and check the CRC and then forward it.

Store and Forward (M.A)

Cut-through

Fragment free

2 more

27.) One switching type is store and forward second is cut through there is another which is the modification of the two what it do

First store packet entirely and then forward it.

Forward the packet when the data approaches the switch.

First receive the 50% of the frame and then forward it. (M.A)

Etc.

I think I got this answer wrong as I know the fragment free switching is first it receive 64 bytes and then start forwarding it but there was no such option. I gave one wrong answer from switching/bridging, one from netowrk protocols, one from OSI and one from Cisco ISO (4 in total). I think this is the one from switching which I done wrong L

28.) What is frame tagging

A unique ID placed in the header of each frame as it traverses the switch fabric (M.A)

A user-assigned ID defined to each frame (M.A)

Examines particular user information about each frame
