Which two configurations are applied on the WLC to enable multicast, check multicast stream subscriptions, and stream content only to subscribed clients? (Choose two)

IGMP snooping causes the WLC to inspect IGMP membership report and leave messages from clients, building a table of which clients have joined which multicast groups so traffic is forwarded selectively rather than to all clients.

Setting the IGMP timeout to 180 seconds defines the interval the WLC waits for a client to renew its group membership before removing it from the subscription table, ensuring the multicast forwarding list stays accurate and stale subscriptions are pruned.

Broadcast forwarding controls how Layer 2 broadcast frames are handled on the wireless network and has no effect on multicast group subscription tracking or selective multicast delivery.

802.3x flow control is a wired Ethernet pause-frame mechanism for congestion management between switches and is unrelated to wireless multicast subscription or forwarding.

Configuring an AP multicast address (e.g., 239.255.255.255) sets the multicast group used for WLC-to-AP data encapsulation in multicast mode, but does not enable subscription checking or restrict streams to only subscribed clients.
