Refer to the exhibit. Assume that no multicast optimization is done on LAN switches A and B. Which feature can be used to optimize multicast traffic forwarding in this situation?

IGMP snooping requires a multicast querier to send periodic IGMP General Queries, which prompt hosts to report their group memberships. Without a PIM-enabled router acting as querier, enabling the IGMP snooping querier feature on the switch fulfills this role, ensuring the switch can maintain its multicast group membership table and forward traffic only to interested ports rather than flooding all ports. This is the correct solution when no upstream multicast router exists to act as the natural querier.

A static MAC entry for the multicast server does not track which ports have interested receivers and therefore does not optimize multicast forwarding.

Disabling IGMP snooping causes the switch to flood multicast traffic to all ports, which is the opposite of optimization.

Disabling the IGMP query election process prevents queries from being sent, causing membership tables to expire and resulting in multicast flooding.

PIM Snooping optimizes PIM protocol traffic between multicast routers, not multicast data forwarding to end hosts on a LAN.
