A WLC receives a coverage hole detection alert from an AP. What two conditions must occur for the controller to dynamically mitigate the situation? (Choose two.)
A. The AP serving the troubled client must currently have a power level 2 or lower.
B. The client must be able to dynamically raise its power level to match the new AP power.
C. The AP must be RF visible to additional APs on the other side of the coverage hole for calibration.
D. The client must have WMM-PS disabled to allow for the increased power usage.
E. The AP serving the troubled client must currently have a power level higher than 2.
A, C
A – need to have some spare power,
C – the CLIENT must be visible for additional APs… (i believe it’s typo).
The controller will also evaluate the client RSSI seen from the other APs. If any other AP can hear such a client above the RSSI threshold, the report is cancelled. This prevents some false positive alerts that could have been caused by sticky clients with poor roaming logic.

A / B is correct.
If it would have a powerlevel higher that 2 it would be 1, and then i would not be able to increase the powerlevel
The AP can use other APs to calculate the coverage hole mitigation (e.g. in case of a sticky client), but it does not need additional APs for it to work. So there is no „must“ of visibility.
A client does not dynamically raise its power level in this case. Quistion “must occur for the conroller’ So B is WRONG
C E
