what should the network administrator’s next action be?

Refer to the exhibit.

Given this output for SwitchC, what should the network administrator’s next action be?

A.
Check the trunk encapsulation mode for SwitchC’s fa0/1 port.

B.
Check the duplex mode for SwitchC’s fa0/1 port.

C.
Check the duplex mode for SwitchA’s fa0/2 port.

D.
Check the trunk encapsulation mode for SwitchA’s fa0/2 port.

Explanation:

Here we can see that this port is configured for full duplex, so the next step would be to
check the duplex setting of the port on the other switch. A mismatched trunk encapsulation
would not result in input errors and CRC errors.
