   A large enterprise is deploying a wireless network for a multicast-based video surveillance system. The system sends video from multiple cameras to a monitoring station. The network administrator wants to ensure that multicast traffic is efficiently forwarded only to the access points that have clients viewing the video. The WLC is connected to a multicast-enabled wired network. Which configuration is necessary on the WLC to achieve this efficiency?

   • AConfigure multicast rate adaptation
   • BEnable multicast-to-unicast conversion
   • CEnable IGMP querier on the WLC
   • DEnable IGMP snooping

   A hospital is deploying a wireless network for a multicast-based patient monitoring system. The system sends vital signs to a group of nurses' tablets. The network administrator wants to ensure that only the tablets that have joined the multicast group receive the data. The WLC is configured with IGMP snooping enabled. What is required for the WLC to learn which tablets are interested in the group?

   • AThe tablets must be configured with a static multicast MAC address
   • BThe WLC must send IGMP queries to the tablets
   • CThe multicast router must send IGMP reports to the WLC
   • DThe tablets must send IGMP membership reports

   A stadium uses multicast to deliver live video to thousands of fans. The network team is considering whether to use multicast direct or multicast-to-unicast conversion. The stadium has a high-density environment with many clients per AP. Which factor is most important in deciding between the two?

   • AThe multicast group address.
   • BThe type of multicast application (video vs data).
   • CThe number of clients interested in the multicast stream.
   • DThe WLC hardware model.

   A hotel offers a wireless service for guests to watch live sports events. The events are multicast from a local server. The network administrator wants to minimize wireless airtime usage while ensuring that guests who join the multicast group receive the video reliably. The number of guests per event is typically between 5 and 15. Which approach best meets these requirements?

   • AIncrease the multicast data rate to the maximum MCS index
   • BEnable multicast-to-unicast conversion for the multicast group
   • CEnable multicast direct with a fixed low data rate
   • DDisable IGMP snooping and let all APs flood the multicast traffic

   Which technique is used to improve reliability of multicast delivery over Wi-Fi?

   • ASending multicast frames multiple times at the lowest data rate.
   • BConverting multicast frames to unicast frames for each interested client.
   • CDisabling IGMP snooping to allow all clients to receive the multicast.
   • DIncreasing the multicast data rate to the maximum supported rate.
