All APs are receiving multicast traffic, instead of only the APs that need it. What is the cause of this problem?
The correct answer is D. Multicast IGMP snooping is not enabled. When IGMP snooping is enabled, multicast traffic is sent only to the ports which sent IGMP joins. If IGMP snooping is disabled, then traffic is flooded to all the ports in that VLAN.
