   What is the role of IGMP snooping in the operation of Multicast Direct?

   • AIt encrypts multicast traffic between the AP and clients
   • BIt helps the AP determine which wireless clients have joined a multicast group
   • CIt converts multicast frames to unicast frames for efficient delivery
   • DIt is not needed because Multicast Direct forwards all multicast traffic to all clients

   An administrator has enabled Multicast Direct on a WLC and wants to verify that it is working correctly. The administrator runs 'show ap multicast direct summary' and sees that the status is 'Enabled' for all APs. However, some clients are not receiving the multicast stream. What is the next step to troubleshoot?

   • ACheck the multicast source for errors.
   • BCheck the IGMP membership of the affected clients.
   • CDisable and re-enable Multicast Direct on the SSID.
   • DReboot the APs to reset the multicast state.

   A network engineer is designing a wireless network for a stadium where a live event will be streamed to thousands of clients. The engineer wants to use Multicast Direct to improve efficiency, but is concerned about the number of unicast frames that will be sent. What is the primary trade-off the engineer must consider?

   • AMulticast Direct eliminates the need for IGMP snooping, simplifying the network.
   • BMulticast Direct reduces the load on the wireless medium because it uses a higher data rate for unicast frames.
   • CMulticast Direct requires a dedicated multicast VLAN, increasing complexity.
   • DMulticast Direct increases the load on the wireless medium because it sends multiple unicast frames instead of one multicast frame.

   A university is deploying a new wireless network for a large lecture hall where professors frequently stream live video to student laptops. The network engineer wants to reduce the load on the wireless medium while ensuring that multicast video is delivered reliably to all interested clients. The WLC is already configured for multicast. What should the engineer do to achieve this goal?

   • ADisable IGMP snooping on the WLC to allow multicast to flood to all clients.
   • BEnable Multicast Direct on the WLC and ensure the APs are in a mode that supports it.
   • CSet the multicast group to a high data rate and enable multicast on the AP radios.
   • DConfigure the WLC to use multicast-to-unicast conversion at the controller level.

   A network engineer is planning to enable Multicast Direct for a new SSID that will carry multicast video to wireless clients. The WLC is already configured for multicast, and the APs are in local mode. The engineer wants to ensure that the feature works correctly. What is the most important configuration step?

   • ASet the multicast data rate to a high value.
   • BConfigure the APs to use a multicast group address.
   • CEnable IGMP snooping on the WLC.
   • DEnable Multicast Direct on the specific SSID.
