   What is the primary role of IGMP snooping in a WLAN?

   • ATo forward multicast traffic only to the access points that have clients subscribed to the multicast group.
   • BTo convert multicast frames into unicast frames for each subscribed client.
   • CTo filter multicast traffic at the access point based on the client's IP address.
   • DTo assign multicast group addresses to clients when they join a group.

   What is directed multicast in the context of WLAN multicast optimization?

   • AA method that sends multicast frames to all clients regardless of their group membership, but at a higher data rate.
   • BA method that uses the multicast MAC address to send frames to a specific client based on its IP address.
   • CA technique that sends multicast frames only to access points that have active group members, using IGMP snooping information.
   • DA technique that converts multicast frames to unicast frames for each client in the group.

   A university is deploying a new WLAN for a large lecture hall where professors frequently stream live video to student devices. The network team is concerned about the impact of low data rates on multicast delivery. They want to ensure that video streams are delivered reliably without flooding the wireless medium. Which configuration should they implement on the WLC?

   • AEnable multicast-to-unicast conversion for the SSID
   • BSet the multicast data rate to 1 Mbps to ensure all clients can receive
   • CConfigure the WLC to use broadcast forwarding for the video stream
   • DDisable IGMP snooping to allow all multicast to flood to all APs

   A company is implementing a new WLAN for a conference center. The network administrator needs to ensure that multicast traffic is delivered only to APs that have clients subscribed to the multicast group. The WLC is currently using the default multicast mode. What configuration change should be made on the WLC?

   • ASet the multicast group address to the WLC's management IP address
   • BConfigure the APs to use directed multicast
   • CEnable multicast-to-unicast conversion on the WLC
   • DEnable IGMP snooping on the WLC

   When configuring multicast on a Cisco wireless LAN controller, what is the purpose of setting a multicast group address?

   • AIt specifies the multicast IP address that the controller uses to communicate with access points for distributing multicast traffic.
   • BIt enables the controller to translate multicast traffic into broadcast traffic for the WLAN.
   • CIt defines the IP address that clients must use to join the multicast group.
   • DIt sets the multicast MAC address used for all client multicast frames on the WLAN.
