Question #41
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.)
  1. A
    Turn off IGMP snooping for all the configured WLANs on the controller.
  2. B
    Implement video-stream for the multicast video on the controller.
  3. C
    Allow multicast-direct to work correctly and multicast-direct to be enabled globally.
  4. D
    Change the WLAN QoS value to Bronze for the WLAN that multicast will be enabled.
  5. E
    Allow RTSP to stream the video due to wireless multicast not using acknowledgements.

Correct Answer:
BC

Question #42
Which two restrictions are in place with regards to configuring mDNS? (Choose two.)
  1. A
    mDNS uses only UDP port 5436 as a destination port.
  2. B

  3. C
    mDNS is not supported on FlexConnect APs with a locally switched WLAN.
  4. D
    Controller software must be newer than 7.0.6+.
  5. E
    mDNS is not supported over IPv6.
