Question:
Refer to the exhibit. A network administrator issued the show etherchannel summary command on the switch S1. What conclusion can be drawn?

• The EtherChannel is suspended.
• The EtherChannel is not functional.
• The port aggregation protocol PAgP is misconfigured.
• FastEthernet ports Fa0/1, Fa0/2, and Fa0/3 do not join the EtherChannel.

Explanation: The EtherChannel status shows as (SD), which means it is a Layer 2 EtherChannel with a status of D or down. Because the EtherChannel is down, the status of the interfaces in the channel group is stand-alone. PAgP is configured on S1, but there is no indication whether it is configured correctly on S1. The problem might also be the adjacent switch EtherChannel configuration.
