Which two statements about redundant trunk groups on EX Series switches are correct? (Choose two.)
Which two statements about redundant trunk groups on EX Series switches are correct? (Choose two.)
Redundant trunk groups on EX Series switches are designed to ensure that if the active link fails, the secondary link can automatically take over, providing a quick failover mechanism without waiting for normal spanning-tree protocol convergence. Additionally, while data traffic is primarily forwarded on the active link and blocked on the secondary link, Layer 2 control traffic is permitted on the secondary link, allowing activities like LLDP sessions to continue between switches on the secondary link.
C,D are correct
If the active link fails, the secondary link automatically starts forwarding data traffic without waiting for normal spanning-tree protocol convergence. Data traffic is forwarded only on the active link. Data traffic on the secondary link is dropped and shown as dropped packets when you issue the operational mode command show interfaces interface-name extensive. 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. https://www.juniper.net/documentation/us/en/software/junos/multicast-l2/topics/topic-map/redundant-trunk-groups.html
