Which two statements about redundant trunk groups on EX Series switches are correct? (Choose two.)

The correct answer is C. Layer 2 control traffic is permitted on the secondary link. D. If the active link fails, then the secondary link automatically takes over. Redundant trunk groups are designed to provide link redundancy. If the primary link fails, the secondary link will automatically take over to ensure continued connectivity.

Explanation

Redundant trunk groups are designed to provide link redundancy. If the primary link fails, the secondary link will automatically take over to ensure continued connectivity. In redundant trunk groups, while regular data traffic is sent over the primary link, Layer 2 control traffic (such as STP, LACP, etc.) is allowed on the secondary link to maintain network stability and protocol operations. map/redundant-trunk-groups.html
