Suggested answer: A

Explanation:

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.
