From the WLC GUI, which RRM setting do you configure to avoid non-Wi-Fi interference?

The correct answer is D. DCA. To avoid non-Wi-Fi interference, the Dynamic Channel Assignment (DCA) setting in the Wireless LAN Controller (WLC) GUI should be configured.

Why each option

To avoid non-Wi-Fi interference, the Dynamic Channel Assignment (DCA) setting in the Wireless LAN Controller (WLC) GUI should be configured.

ACoverage

Coverage settings primarily deal with signal strength and cell size, not directly with avoiding non-Wi-Fi interference sources by changing channels.

BTPC

Transmit Power Control (TPC) adjusts the power of the APs to optimize cell size and minimize co-channel interference, but it does not address non-Wi-Fi interference by changing channels.

CGeneral

General settings encompass broad configurations, but there isn't a specific 'General' setting within RRM that directly controls non-Wi-Fi interference avoidance through channel changes.

DDCACorrect

Dynamic Channel Assignment (DCA) is an RRM (Radio Resource Management) feature that continuously monitors RF conditions, including non-Wi-Fi interference sources, and automatically adjusts channel assignments for APs. By intelligently changing channels, DCA mitigates the impact of detected non-Wi-Fi noise on wireless performance.
