Question

What are two benefits of 802.3ad link aggregation? (Choose two)

Options

AIt increases bandwidth
BIt ensures symmetrical paths
CIt simplifies interface configuration.
DIt creates physical layer redundancy.

Explanation

Aggregating multiple links between physical interfaces creates a single logical point-to-point trunk link or a LAG. The LAG balances traffic across the member links within an aggregated Ethernet bundle and effectively increases the uplink bandwidth. Another advantage of link aggregation is increased availability, because the LAG is composed of multiple member links. If one member link fails, the LAG continues to carry traffic over the remaining links. switches/topics/topic-map/switches-interface-aggregated.html
