The correct answer is C. Enable IGMP snooping on Acc-1 VLANs. Since all clients on Acc-1 are receiving the multicast stream, the switch is flooding multicast traffic like broadcast.

Question
Refer to the exhibit. During some implementation tests, you find that multicast traffic is being received on every client on the Acc-1 switch. What needs to be modified for multicast traffic to be forwarded appropriately?

Explanation
Since all clients on Acc-1 are receiving the multicast stream, the switch is flooding multicast traffic like broadcast. To forward multicast traffic only to interested receivers, IGMP snooping must be enabled on the VLANs of Acc-1. IGMP snooping listens to IGMP join/leave messages and builds per-VLAN multicast forwarding tables, ensuring only subscribed ports receive the multicast traffic.
