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.
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?
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.
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?
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. |
