Question:
A network administrator configured an EtherChannel link with three interfaces between two switches. What is the result if one of the three interfaces is down?

• The remaining two interfaces continue to load balance traffic.
• The remaining two interfaces become separate links between the two switches.
• One interface becomes an active link for data traffic and the other becomes a backup link.
• The EtherChannel fails.

Explanation: EtherChannel creates an aggregation that is seen as one logical link. It provides redundancy because the overall link is one logical connection. The loss of one physical link within the channel does not create a change in the topology; the EtherChannel remains functional.
