A network administrator is configuring an EtherChannel link between two physical ports on a switch. Which statement describes the result when one of the physical ports fails?

• An STP recalculation is needed.
• The EtherChannel link fails.
• The EtherChannel stops transmitting data until it is restarted.
• The EtherChannel continues transmitting data with reduced bandwidth.

Explanation: An EtherChannel is seen as one logical connection. The loss of one physical link within the channel does not create a change in the topology and therefore a spanning tree recalculation is not required. When one of the member ports in the EtherChannel fails, the EtherChannel link remains functional, although its overall throughput decreases because of a lost link within the EtherChannel.
