Q

Refer to the show ip route command output from RouterA above. If you ping a device in the network 172.23.0.0 from the router, what does the router do with the packets?

A. It drops the packets.

B. It forwards the packets to next-hop address 10.1.1.1.

C. It forwards the packets to next-hop address 10.1.1.2.

D. It forwards the packets to network 172.16.1.0/24.

E. It forwards the packets to next-hop address 192.168.10.2.

F. It delivers the packets directly to the device on network 172.23.0.0.

A

B. It forwards the packets to next-hop address 10.1.1.1.

The correct answer is “It forwards the packets to next-hop address 10.1.1.1.” The router forwards the packets to the default gateway, 10.1.1.1, because the packets are destined for a network that is not explicitly found in the routing table.

Q

Which statement about the administrative distance feature of Cisco routers is correct?

A. Static routes have a default administrative distance of 1 and therefore pre-empt all other entries for that destination network.

B. Routing protocols have an administrative distance of 4.

C. The higher the administrative distance value, the more reliable the source.

D. Administrative distance represents the trustworthiness of the route source.

E. Administrative distance represents the number of router interfaces that a packet must travel through before reaching its destination.

A

D. Administrative distance represents the trustworthiness of the route source.

The correct answer is “Administrative distance defines the trustworthiness of the route source.” Routers use administrative distance to select the best path when they learn two or more different routes to the same destination. Administrative distance defines the reliability of the route source—the smaller the administrative distance value, the more trusted the source.

Q

According to the command output, how are packets that are bound for the network 192.168.2.0 forwarded?

RouterX# show ip route
D 192.168.1.0/24 [90/25789217] via 10.1.1.1
