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

Question

Options

• ALayer 2 control traffic is permitted on the secondary link.
• BIf the active link fails, then the secondary link automatically takes over.
• CRedundant trunk groups load balance traffic across two designated uplink interfaces.
• DRedundant trunk groups use spanning tree to provide loop-free redundant uplinks.

• A
  83% (25)
• B
  3% (1)
• C
  10% (3)
• D
  3% (1)

Explanation

A: While data traffic is blocked on the secondary link, Layer 2 control traffic is still permitted. For example, an LLDP session can be run between two switches on the secondary link. B: The redundant trunk group is configured on the access switch and contains two links: a primary or active link, and a secondary link. If the active link fails, the secondary link automatically starts forwarding data traffic without waiting for normal spanning-tree protocol convergence. groups-understanding.html
