Question 1

There are several differences between IS-IS Hello packets used on broadcast interfaces and on pointto-point interfaces. Which of the following statements is FALSE?

A : On broadcast interfaces there are different Hello packet types for level-1 and level-2 adjacencies, whereas on point-to-point interfaces there is a single Hello packet type.

B : The multicast MAC addresses to which the Hello messages are sent are different on broadcast interfaces and on point-to-point interfaces.

C : The neighbors are identified using their interface MAC addresses on broadcast Hello messages and using their system IDs on point-to-point Hello messages.

D : Broadcast Hello messages identify the elected designed IS (DIS) and point-to-point Hello messages do not.

Answer: C

Question 2

A routing domain is using a single-area link-state routing protocol. Which of the following is NOT information that a router can share with other routers in the domain using protocol-specific messages?

A : The IP prefixes of subnets directly attached to the router.

B : IP prefixes known by the router because it is running ad additional routing protocol.

C : A copy of the local routing table.

D : The local router ID and the router IDs of neighboring routers.

Answer: C

Question 3

There are several differences between IS-IS Hello packets used on broadcast interfaces and on pointto-point interfaces. Which of the following statements is FALSE?

A : On broadcast interfaces there are different Hello packet types for level-1 and level-2 adjacencies, whereas on point-to-point interfaces there is a single Hello packet type.

B : The multicast MAC addresses to which the Hello messages are sent are different on broadcast interfaces and on point-to-point interfaces.

C : The neighbors are identified using their interface MAC addresses on broadcast Hello messages and using their system IDs on point-to-point Hello messages.

D : Broadcast Hello messages identify the elected designed IS (DIS) and point-to-point Hello messages do not.

Answer: C

Question 4

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?

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

B : Route tables can be reduced by summarizing the IP prefixes advertised between areas.

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

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

Answer: D
