Explanation

In Cisco Video Mesh deployments, clients use STUN-measured round-trip times to select the optimal media cluster. The selection priority is: on-premises Video Mesh clusters first (lower latency is preferred over cloud), then Webex Cloud Media Clusters (WCMC) as fallback. Based on the exhibit's delay values, DC Europe is the lowest-latency on-premises cluster, so it is selected first. If DC Europe is full or unavailable, the client falls back to the cloud cluster with the next-lowest measured latency, which is US West Coast WCMC. Answer C correctly describes this: on-premises first (DC Europe), then cloud fallback (US West Coast WCMC).
