An engineer must enable multicast traffic on a specific WLAN named MLTCST48904392 but not the entire network. Which protocol must the engineer use?

DCA (Dynamic Channel Assignment) is an RRM algorithm used by Cisco controllers to automatically select the best operating channel for APs, and has no relation to multicast traffic.

WMM (Wi-Fi Multimedia) is a QoS mechanism that prioritizes traffic categories such as voice and video over the wireless medium, but it does not control multicast forwarding behavior.

TPC (Transmit Power Control) is an RRM feature that automatically adjusts AP transmit power to optimize coverage and reduce interference, and is unrelated to multicast traffic management.

WMF (Wireless Multicast Forwarding) is a Cisco feature that converts multicast traffic to unicast for delivery to wireless clients on a specific WLAN, improving reliability and efficiency. It can be enabled on an individual WLAN without affecting other WLANs or the broader network. This per-WLAN granularity is exactly what the requirement describes.
