Explanation

In multicast networks, filtering should be applied as close to the receiver as possible to avoid wasting bandwidth on links leading to that receiver. S1 is the switch directly connected to receiver A. By placing the filter on S1 (using IGMP snooping policies or port-level access control), multicast traffic is blocked before it reaches receiver A's segment. Filtering at routers R1 or R2 would either be too far upstream or affect other receivers, and filtering at the video conference source or on the receiver itself is less efficient or less appropriate.
