Assuming this MX has established a full tunnel with its VPN peer, how will the MX route the WebEx traffic?

Show Suggested Answer Hide Answer
Suggested Answer: A

Assuming this MX has established a full tunnel with its VPN peer, the MX will route the WebEx traffic based on the SD-WAN policy configured in the exhibit. The SD-WAN policy has two performance classes:ConfandDefault.TheConfperformance class matches the traffic with destination port 9000, which is used by WebEx for VoIP and video RTP3. TheConfperformance class has a preferred uplink of WAN 2 and a failover uplink of WAN 1. It also has thresholds for latency, jitter, and loss that determine when to switch from the preferred uplink to the failover uplink. Therefore, the WebEx traffic will prefer WAN 2 as long as it meets the thresholds in theConfperformance class. If WAN 2 exceeds the thresholds or goes down, the WebEx traffic will switch to WAN 1 as the failover uplink.

Exactly! Balancing could help with that.

D could be a good option too. Load balancing is efficient.

C makes sense. As long as WAN 2 is up, it should route there.

I lean towards A. If it meets the thresholds, why not?

I think it's B. Primary uplink should handle it.

Wait, I didn't know WebEx could route like that!

D) is a possibility, but I doubt it would load-balance in this case.

C) sounds right, as long as WAN 2 is up, it should route there.

I think B) makes more sense, WAN 1 is primary after all.

A) is correct if WAN 2 meets the performance class.

I feel like C could be the right choice since it mentions WAN 2 being preferred as long as it's up, which makes sense for redundancy.

I’m a bit confused about whether the traffic would really load-balance or not. D seems plausible, but I’m not confident.

I remember a similar question where the primary uplink was emphasized, so I’m leaning towards B.

I think the answer might be A, but I'm not entirely sure how the performance class thresholds work in this scenario.
