21Which 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.

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.

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.

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.

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.

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

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.

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.

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.

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.

31 Routers can learn about destinations through static routes,

default, or dynamic routing. By default, a router will use

information derived from __________.

A. IGRP

B. RIP

C. IP

D. TCP

Ans A

The quality of information is rated:

Connected interface 0

Static route 1

IGRP 100

RIP 120

Unknown 255

The lower the value, the more reliable the source with 255

signifying information that the router will ignore. So, the

router will use IGRP, rated at 100, before RIP, rated at

120.

32 You are logged into a router, what command would

show you the IP addresses of routers connected to you?

A. show cdp neighbors detail

B. show run

C. show neighbors

D. show cdp

Ans A

33 As a system administrator, you perform an extended ping at

the privileged EXEC prompt. As part of the display, you see

“Set DF bit in IP header? [yes] :” What would happen if you

answered no at the prompt.

A. This lets the router fragment the packet.

B. It tells the router not to fragment the packet.

C. This lets the router direct the packet to the destination

it finds in its routing table.

D. It tell the router to send the packet to the next hop

router.

Ans A

“Set DF bit in IP header?” is a response to an

extended ping at the router. If you answer yes (the default)

the router will not fragment the packet. If you answer no,

the router will fragment the packet.

34 You have typed “ping” 172.16.101.1 and get the following

display:

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echoes to 172.16.101.1,

timeout is 2 seconds:

.!!!!

What does the “.” signify?

A. That one message timed out.

B. That all messages were successful.

C. That one message was successful.

D. That one message completed in under the allotted

timeframe.

Ans A

The possible responses from the ping command are:

! Successful receipt of an echo reply.

. Timed out waiting for a reply

U Destination unreachable

C Congestion-experienced packet

I Ping interrupted

? Packet type unknown

& Packet TTL exceeded

35 Which command, that is used to test address configuration,

uses Time-To-Live (TTL) values to generate messages from

each router.

A. trace

B. ping

C. telnet

D. bootp

Ans: A

The Cisco IOS EXEC command “trace [protocol]

[destination]” is used to discover routes that packets will

travel to their destination hosts. Trace uses TTL (Time to

Live) values to report destination route information.

36 What does the command “IP name-server 255.255.255.255″

accomplish?

A. It sets the domain name lookup to be a local broadcast.

B. This is an illegal command.

C. It disables domain name lookup.

D. The command is now defunct and has been replaced by “IP

server-name ip any”

Ans A

By default DNS is enabled on a router with a

server address of 255.255.255.255, which provides for a

local broadcast.

37 As a system administrator, you need to provide your routers

with a Domain Name System (DNS) server. How many DNS

servers can you specify with one command?

A. 6

B. 1

C. 2

D. 4

Ans A

You can only specify six name servers in one

command. The syntax is “IP name-server server-address1 [[

server-address2 ]…server-address6]. You must also enable

DNS.

38 How would you configure one host name that points to two IP

addresses?

A. IP host jacob 1.0.0.5 2.0.0.8

B. IP jacob 1.0.0.5 2.0.0.8

C. IP host jacob 1.0.0.5

D. IP host duplicate “all”

Ans A

The correct syntax is IP host name [

TCP-port-number ] address [ address ]….. So, “IP host

P1R1 1.0.0.5 2.0.0.8″ is the correct choice. “IP host jacob

1.0.0.5″ only points the host name jacob to one IP

address–1.0.0.5.

39 The following selections show the command prompt and the

configuration of the IP network mask. Which two are

correct?

A. Router#term IP netmask-format { bitcount | decimal | hexadecimal }

B. Router(config-if)#IP netmask-format { bitcount | decimal | hexadecimal }

C. Router(config-if)#netmask-format { bitcount | decimal | hexadecimal }

D. Router#ip netmask-format { bitcount | decimal | hexadecimal }

Ans A & B

Router#term IP netmask-format { bitcount |

decimal | hexadecimal } and Router(config-if)#IP

netmask-format { bitcount | decimal | hexadecimal } are

correct. You can configure the mask for the current session

and you can configure it for a specific line.

40 When configuring the subnet mask for an IP address, which

formats can be used?A. dotted-decimal.

B. Hexadecimal

C. Bit-count

D. Octal

E. Binary

Ans A, B &C
