Refer to the exhibit. Serial0/0 does not respond to a ping request from a host on the
FastEthernet0/0 LAN. How can this problem be corrected?

A.
Change the encapsulation type on Serial 0/0.

B.
Enable autoconfiguration on the Serial 0/0 interface.

C.
Correct the IP address for Serial 0/0.

D.
Correct the IP address for FastEthernet 0/0.

E.
Enable the Serial 0/0 interface.

Explanation:
The status of the interface shows “administratively down” which means that the interface was
manually shut down, or it was never enabled in the first place. This interface needs to be enabled
using the “no shutdown” command under interface serial 0/0 in the configuration.
