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

Show Suggested Answer Hide Answer
Suggested Answer: B, D

Redundant Trunk Groups (RTGs) on EX Series switches provide a simple solution for network recovery when a trunk port on a switch goes down1.They are configured on the access switch and contain two links: a primary or active link, and a secondary link1.Therefore, option B is correct because if the active link fails, the secondary link automatically starts forwarding data traffic without waiting for normal spanning-tree protocol convergence1.

Option D is also correct.In a typical enterprise network composed of distribution and access layers, RTGs are used where one Access switch is connected to two different uplink switches2.This implies that RTGs must be connected to the same aggregation switch2.

Redundant trunk groups, huh? Sounds like a fancy way of saying 'backup cables'. As long as it works, that's all that matters!

C? Layer 2 control traffic on the secondary link? That's a bit odd. I'm not so sure about that one.

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

I agree with you, Stevie. A and B make sense because they ensure traffic is balanced and failover is automatic.

D is definitely true. Gotta have the redundant links connected to the same switch for it to work properly.

A and B sound about right. Load-balancing and failover - that's what I'd expect from redundant trunk groups.
