Suggested answer: B

Explanation:

In an EVPN-VXLAN environment, to ensure that multicast traffic is delivered only to leaf devices with interested receivers, IGMP snooping is required. IGMP snooping enables the leaf devices to listen to IGMP report and leave messages from hosts and make forwarding decisions based on this information. This way, multicast traffic is only forwarded to ports with interested multicast group members, optimizing bandwidth and resource utilization.
