CCNA Practice Exam Test Sample – Question 83

Refer to the exhibit.
q83-q
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.

Correct Answer: C
Section: LAN Switching Technologies

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.
