Question 1

Refer to the exhibit.Routers R1 through R4 are running an IGP in such a way that they have each others 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. 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?

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

B : Router R2 drops the echo request because it does not have subnet 10.4.100.0 in its routing table.

C : Router R3 drops the echo request because it does not have subnet 10.4.100.0 in its routing table.

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

Answer: D

Question 2

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
