A wireless engineer is calibrating a floor using Cisco Prime Infrastructure. Which setting in the WLC must be disabled before the floor calibration is started?
The correct answer is B. Dynamic Channel Assignment. Floor calibration in Cisco Prime Infrastructure requires APs to remain on fixed, known channels so that the calibration data (signal measurements, RSSI readings) is consistent and reproducible. Dynamic Channel Assignment (DCA) is a Radio Resource Management (RRM) feature on the…

Explanation
Floor calibration in Cisco Prime Infrastructure requires APs to remain on fixed, known channels so that the calibration data (signal measurements, RSSI readings) is consistent and reproducible. Dynamic Channel Assignment (DCA) is a Radio Resource Management (RRM) feature on the WLC that automatically adjusts AP transmit channels based on RF conditions. If DCA is running during calibration, channels can change mid-survey, invalidating the collected data and producing an inaccurate calibration model. CleanAir, Coverage Hole Detection, and Tx Power Control do not interfere with channel consistency during floor calibration, so they do not need to be disabled.
