93 What must be true for two Routers running IGRP to
communicate their routes?
A.) Same autonomous system number
B.) Connected using Ethernet only
C.) Use composite metric
D)Configured for PPP
Ans A
94 The following is partial output from a routing table,
identify the 2 numbers in the square brackets; '192.168.10.0
[100/1300] via 10.1.0.1, 00:00:23, Ethernet1'
A.) 100 = metric, 1300 = administrative distance
B.) 100 = administrative distance, 1300 = hop count
C.) 100 = administrative distance, 1300 = metric
D.) 100 = hop count, 1300 = metric
Ans C
95 Identify 3 methods used to prevent routing loops?
A.) Split horizon
B.) Holddown timers
C.) Poison reverse
D.) SPF algorithm
E.) LSP's
Ans A B C
96 Which statement is true regarding full duplex?
A.) Allows for transmission and receiving of data
simultaneously
B.) Only works in a multipoint configuration
C.) Does not affect the bandwidth
D.) Allows for transmission and receiving of data but not a the
same time
Ans A
Full duplex is just the opposite of half duplex. It handles
traffic in both directions simultaneously.
97 Identify the switching method that receives the entire
frame then dispatches it?
A.) Cut-through
B.) Receive and forward
C.) Store and forward
D.) Fast forward
Ans C
Store and forward switching receives the entire frame before
dispatching it.
98Identify the purpose of ICMP?
A.) Avoiding routing loops
B.) Send error and control messages
C.) Transporting routing updates
D.) Collision detection
Ans B
ICMP is used to send error and control messages. Ping uses ICMP
to carry the echo-request and echo-reply.
99Which statement is true regarding the user exec and
privileged exec mode?
A.) The '?' only works in Privileged exec
B.) They are identical
C.) They both require the enable password
D.) User exec is a subset of the privileged exec
Ans D
The user exec mode is a subset of the privileged exec mode. Only
a certain number of commands are available at the user exec
mode.

and re-assembly?
A.) Network
B.) Transport
C.) Physical
D.) Application
E.) Data-Link
F.) Presentation
Ans B
