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

Show Suggested Answer Hide Answer
Suggested Answer: C, D

Cis correct because Layer 2 control traffic is permitted on the secondary link of a redundant trunk group (RTG) on EX Series switches.Layer 2 control traffic includes protocols such as LLDP, LACP, and STP, which are used to exchange information and coordinate actions between switches1.According to the Juniper Networks documentation2, Layer 2 control traffic is allowed to pass through both the active and the secondary links of an RTG, but data traffic is only forwarded through the active link. This allows the switches to maintain their Layer 2 adjacencies and monitor the link status on both links.

Dis correct because if the active link fails, then the secondary link automatically takes over in an RTG on EX Series switches.An RTG consists of two trunk links: an active or primary link, and a secondary or backup link2. The active link is used to forward data traffic, while the secondary link is in standby mode.If the active link fails or becomes unavailable, the secondary link immediately transitions to a forwarding state and takes over the data traffic without waiting for normal STP convergence2. This provides fast recovery and redundancy for the network.

I'm not sure about C and D. Can someone explain why they are not correct?

I'd go with A and B. Load-balancing across the uplink interfaces and automatic failover on link failure are critical for redundancy.

I agree with Desmond. A and B make sense because they ensure traffic balance and failover.

B and D seem to be the correct options here. The secondary link should take over if the active link fails, and the redundant trunk group should be connected to the same aggregation switch.
