   A retail chain wants to deploy digital signage over Wi-Fi to many stores. The signage players are wireless and need to receive the same video stream reliably. The network team is concerned about wireless airtime usage. What is the primary benefit of using Multicast Direct for this deployment?

   • AIt allows multicast traffic to be sent at the same data rate as unicast traffic.
   • BIt converts multicast to unicast per client, allowing retransmissions and higher data rates.
   • CIt eliminates the need for IGMP snooping on the WLC.
   • DIt reduces the load on the wired network by compressing multicast traffic.

The network team wants to ensure that the displays receive the stream reliably without overwhelming the Wi-Fi. What is the main advantage of Multicast Direct over traditional multicast delivery?

   • AIt provides per-client reliability through unicast retransmissions.
   • BIt allows multicast traffic to be sent at the same data rate as unicast traffic.
   • CIt reduces the load on the wired network by using multicast compression.

   • AThe multicast group address is not in the range 224.0.0.0/4.
   • BMulticast Direct is not enabled on the specific SSID.
   • CThe WLC is in FlexConnect mode and the APs are not configured for local switching.
   • DThe APs are not in local mode.
