A routing domain uses a link-state routing protocol. Which of the following would NOT be an advantage of dividing the entire routing domain into areas?

ADetailed topology information is only shared among routers within the same area, thus reducing the complexity of the SPF calculation.

BRoute tables can be reduced by summarizing the IP prefixes advertised between areas.

CLess-capable routers can be isolated from having to keep track of IP prefixes that are external to the local routing domain.

DFewer routers are required to handle the same amount of traffic, as compared to a single-area domain.

Question 2

Which of the following is NOT a required configuration step to successfully run IS-IS on a router?

AThe router needs to be associated with an IS-IS area ID.

BLayer-3 interfaces that will participate in IS-IS need to be identified.

CA reference bandwidth needs to be configured to calculate link costs.

DThe IS-IS context needs to be enabled.

Question 3

Consider the exhibit.

All routers are running IS-IS with IPv6 support enabled. Based on the topology shown, and the route tables of routers R3 and R4, which of the following statements is TRUE?

AThere is no route leaking configured on router R1 or router R2.

BRoute leaking is configured on router R1 but not on router R2.

CRoute leaking is configured on router R2 but not on router R1.

DRoute leaking is configured on both routers R1 and R2.

Question 4

Two IS-IS routers are exchanging Hello packets. One is configured to use authentication and the other is not. Which of the following statements is TRUE?

AAn adjacency will be established with authentication using the default parameters defined for IS-IS routers.

BThe two routers will negotiate the authentication parameters and the establish an adjacency.

CAn adjacency will be established without authentication.

DAn adjacency will not be established.

Question 5

Refer to the exhibit.

Routers R1 through R4 are running an IGP in such a way that they have each other's system IP addresses in their routing tables. A static route is configured on router R1 so that it can reach subnetwork 10.4.100.0/24. The network administrator decides to use an indirect static route, as shown in the diagram. However, pinging the server from router R1 fails. What may be the problem in this case?

ARouter R1 drops the echo request because address 10.10.10.3 does not belong to an adjacent router.

BRouter R2 drops the echo request because it does not have subnet 10.4.100.0/24 in its routing table.

CRouter R3 drops the echo request because it does not have subnet 10.4.100.0/24 in its routing table.

DThe echo request arrives at the server but there is no path for the echo response to return to router R1.
