Implementing Cisco Enterprise Wireless Networks (ENWLSI) — Question 81

A wireless network has been implemented to enable multicast video to be streamed reliably over the wireless link to the wireless users. After a client reports that the video is unable to stream, the administrator determines that the client is connecting at a data rate of 12 Mbps and is trying to stream to a valid multicast address on the network. Which two actions must be applied? (Choose two.)

Answer options

• A. Turn off IGMP snooping for all the configured WLANs on the controller.
• B. Implement video-stream for the multicast video on the controller.
• C. Allow multicast-direct to work correctly and multicast-direct to be enabled globally.
• D. Change the WLAN QoS value to Bronze for the WLAN that multicast will be enabled.
• E. Allow RTSP to stream the video due to wireless multicast not using acknowledgements.

Correct answer: B, C

Explanation

The correct answer options B and C address the necessary configurations to support multicast video streaming effectively on the network. Turning off IGMP snooping (option A) may lead to issues with multicast traffic management, while adjusting the WLAN QoS value (option D) does not directly enable multicast features. Allowing RTSP (option E) is irrelevant since the problem pertains to the multicast setup rather than the streaming protocol.
