Which technique is commonly used to mitigate the impact of multicast on wireless networks?

Increasing the multicast data rate to the maximum supported rate to reduce airtime.

Using a higher transmit power for multicast frames to ensure all clients receive them.

Multicast-to-unicast conversion, where the AP sends a separate unicast frame to each client in the multicast group.

Disabling multicast on the wireless network to prevent any multicast traffic from being sent.

What is the purpose of multicast rate optimization in a wireless network?

To increase the number of retransmissions for multicast frames to improve reliability.

To convert multicast frames to unicast frames and send them at the highest data rate.

To select the highest possible data rate for multicast frames to minimize airtime while ensuring all group members can receive the traffic.

To force all multicast frames to be sent at the lowest data rate to guarantee reception by all clients.

A hotel offers a wireless network for guests. The network uses multicast for in-room entertainment streaming. Guests report that the video quality is poor on devices far from the AP. The network uses default multicast settings. What is the primary reason for the poor quality on distant devices?

The AP sends multicast frames only to clients that have requested the stream via IGMP, and distant clients are not included.

The AP uses a high multicast rate to conserve airtime, which distant clients cannot receive.

Multicast frames are sent at a low data rate that is decodable by all clients, but the lack of acknowledgments causes losses at the cell edge.

The multicast stream is encrypted with a different key, and distant devices cannot decrypt it.
