IAM POSTING THE CCNA INTERVIEW QUESTIONS PDF DOC WITH ANSWERS OF CCNA AND THESE QUESTIONS WILL HELP YOU ALL, AND ALSO YOU CAN FIND MANY TUTORIALS IN THE BELOW
Question 21
Which NetWare protocol provides link-state routing?
A. NLSP
B. RIP
C. SAP
D. NCP
Ans: A
NetWare Link Services Protocol (NLSP) provides link-state routing. SAP (Service Advertisement Protocol) advertises network services. NCP (NetWare Core Protocol) provides client-to-server connections and applications. RIP is a distance vector routing protocol.
Question 22
As a system administrator, you want to debug igrp but are worried that the “debug IP igrp transaction” command will flood the console. What is the command that you should use?
A. debug IP igrp event
B. debug IP igrp-events
C. debug IP igrp summary
D. debug IP igrp events
Ans D
The “debug IP igrp events” is used to only display a summary of IGRP routing information. You can append an IP address onto either command to see only the IGRP updates from a neighbor.
Question 23
What does the following series of commands accomplish? router igrp 71 network 10.0.0.0 router igrp 109 network 172.68.7.0
A. It isolates networks 10.0.0.0 and 172.68.7.0.
B. It loads igrp for networks 109 and 71.
C. It disables RIP.
D. It disables all routing protocols.
Ans A
It isolates network 10.0.0.0 and 172.68.7.0 and associates autonomous systems 109 and 71 with IGRP. IGRP does not disable RIP, both can be used at the same time.
Question 24
In the command “router igrp 109″ what does 109 signify?
A. an autonomous system
B. any network number which the router is attached to
C. the allowable length of the routing table
D. the network socket number
Ans A
The Cisco IOS global configuration command “router igrp xxx” is used to configure the Interior Gateway Routing Protocol. In this case, the 109 is called the process-id , which can also be used for an autonomous system number.
Question 25
IGRP supports a feature that allows traffic to be distributed among up to 6 (4
default) paths to provide greater overall throughput and reliability. What is this called?
A. unequal-cost load balancing
B. equal-cost load balancing
C. proportionate load balancing
D. low cost load balancing
Ans A
An unequal-cost load balancing is used to provide alternate paths for data distribution on an internetwork. Cisco developed this method to use unused or under utilized links to increase bandwidth and network availability.
Question 26
IGRP uses flash updates, poison reverse updates, holddown times, and split horizon. How often does it broadcast its routing table updates?
A. 90 seconds
B. 10 seconds
C. 30 seconds
D. 45 seconds
Ans A
Question 27
The command “show IP protocol” displays which information?
A. routing timers
B. network information
C. contents of the IP routing table
D. information about all known network and subnetworks
Ans A & B
“show IP protocol” displays routing timers and network information. “show IP route” displays the routing table with information about all known networks and subnetworks.
Question 28
When using RIP, routing updates are broadcast every ____ seconds.
A. 30
B. 10
C. 60
D. 90
Ans: A
Novell’s RIP updates routing tables every 60 seconds, Apple’s RTMP is every 10 seconds, routers ARP every 60 seconds, DECnet hosts and IGRP signal every 15 seconds, and Banyan VINES signals every 90 seconds.
Question 29
An autonomous system can only exist if all routers in that system meet which criteria?
A. interconnected
B. run the same routing protocol
C. assigned same autonomous system number
D. run IGRP only
E. run RIP only
Ans A,B &C
An autonomous system is a set of routers and networks under the same administration. Each router must be interconnected, run the same routing protocol, and assigned the same autonomous system number. The network Information Center (NIC) assigns a unique autonomous system number to enterprises.
Question 30
A default route is analogous to a _________.
A. default gateway
B. static route
C. dynamic route
D. one-way route
Ans: A
A default route is analogous to a default gateway. It is used to reduce the length of routing tables and to provide complete routing capabilities when a router might not know the routes to all other networks.
