Which statement about a Cisco Mesh Network when a radar event is detected by the MAP on a mesh tree when coordinated channel change is enabled is true? 

Answer options:

A. The MAP immediately stops transmission on the current channel and joins the parent after 30 minutes after the channel is marked as clean.
B. The MAP propagate radar event information to the RAP in the same BGN, searches for a different parent working on a non-dfs channel, and joins there.
C. The MAP continues transmission of the beacons and probes for 10 seconds after the radar detection and suspends operation for the next 30 mins.
D. The MAP propagates the radar event information to the RAP and the whole sector moves to the new channel.

A

If the mesh access point does detect radar, the controller and the mesh access point both will retain the channel as the configured channel. The controller retains it in volatile memory associated with the mesh access point, and the mesh access point has it stored in its flash as configuration. After the 30 minute quiet period, the controller returns the mesh access point to the static value, regardless of whether the mesh access point has been configured with a new channel or not. In order to overcome this, configure the mesh access point with a new channel, and reboot the mesh access point.
