RTA is configured with a basic configuration. The link between the two routers is operational and no routing protocols are configured on either router. The line shown in the exhibit is then added to router RTA. Should interface Fa0/0 on router RTB shut down, what effect will the shutdown have on router RTA?

Refer to the exhibit.

A. A route to 172.16.14.0/24 will remain in the RTA routing table.

B. A packet to host 172.16.14.225 will be dropped by router RTA.

C. Router RTA will send an ICMP packet to attempt to verify the route.

D. Because router RTB will send a poison reverse packet to router RTA, RTA will remove the route.

Answer: A

Explanation:

Static routes remain in the routing table even if the specified gateway becomes unavailable. If the specified gateway becomes unavailable, you need to remove the static route from the routing table manually.

However, static routes are removed from the routing table if the specified interface goes down, and are reinstated when the interface comes back up. Therefore the static route will only be removed from the routing table if the S0/0 interface on RTA is shutdown.
