A company is deploying a WLAN for a large auditorium where live events are streamed to attendees' devices. The network administrator is concerned about the reliability of multicast delivery because wireless multicast does not use acknowledgments. What should the administrator do to improve reliability?

Disable IGMP snooping to allow multicast to be broadcast to all clients

Increase the multicast data rate to the maximum supported rate

Set the multicast group address to a unicast address

Enable multicast-to-unicast conversion for the event SSID

A retail store is deploying a WLAN for a digital signage system that sends the same video stream to multiple displays. The displays are stationary and have good signal strength. The network administrator wants to ensure that the multicast stream is delivered reliably without excessive airtime usage. What should the administrator configure?

Use native multicast forwarding with IGMP snooping and set the multicast data rate to a moderate rate

Disable IGMP snooping to ensure all displays receive the stream

Set the multicast data rate to the highest supported rate

Enable multicast-to-unicast conversion for the signage SSID

A client is not receiving multicast traffic on a WLAN. What is the first troubleshooting step to verify that the client is actually part of the multicast group?

Confirm that the client's wireless adapter supports multicast.

Verify that the client has sent an IGMP membership report for the multicast group.

Check the access point's multicast data rate settings.

Check the client's IP address and subnet mask.

A manufacturing plant uses a WLAN for a multicast-based machine monitoring system. The system sends alerts to a group of tablets. Recently, some tablets stopped receiving alerts. The WLC has IGMP snooping enabled. The administrator checks the WLC and sees that the multicast group membership table is empty for the affected tablets. What is the most likely cause?

The tablets are not sending IGMP membership reports

The multicast source is not sending traffic

The APs are not forwarding multicast due to a firmware bug

The multicast group address is misconfigured on the WLC

A network administrator is troubleshooting a multicast issue on a WLAN. Clients are unable to receive multicast streams from a server on the wired network. The WLC has IGMP snooping enabled, and the multicast group address is correctly configured. What should the administrator check next?

Check the upstream switch to ensure that IGMP snooping is enabled and the WLC's port is a member of the multicast group

Verify that the multicast group address is within the range 224.0.0.0 to 239.255.255.255

Change the multicast forwarding method to multicast-to-unicast conversion

Disable IGMP snooping on the WLC to allow multicast to be flooded to all APs
