After looking in the logs, an engineer notices that RRM keeps changing the channels for non-IEEE 802.11 interferers.
After surveying the area, it has been decided that RRM should not change the channel.
Which feature must be enabled to ignore non-802.11 interference?

A. B. C. D.B.
The correct answer to this question is option C - "Avoid Persistent Non-WiFi Interference".
RRM (Radio Resource Management) is a feature in Cisco wireless controllers that automatically adjusts the channel and power settings of access points (APs) to optimize the wireless network's performance and coverage. RRM continuously monitors the wireless environment and makes adjustments to the channel and power settings of APs to avoid interference and improve signal quality.
In this scenario, the engineer noticed that RRM is changing the channels for non-IEEE 802.11 interferers, which indicates that RRM is detecting interference from non-Wi-Fi sources such as Bluetooth devices, microwave ovens, or cordless phones. However, the engineer has surveyed the area and determined that the non-Wi-Fi interference is persistent and not likely to go away, so RRM should not change the channel.
To prevent RRM from changing the channel for persistent non-Wi-Fi interference, the "Avoid Persistent Non-WiFi Interference" feature must be enabled on the wireless controller. This feature instructs RRM to avoid changing the channel for non-Wi-Fi interference that persists for a specified period.
Option A - "Avoid Cisco AP Load" is a feature that instructs RRM to avoid channel changes that would cause an AP to become overloaded.
Option B - "Avoid Non-802.11 Noise" is a feature that instructs RRM to avoid changing the channel for non-Wi-Fi interference, including Bluetooth and ZigBee.
Option D - "Avoid Foreign AP Interference" is a feature that instructs RRM to avoid changing the channel for interference from neighboring APs that are not part of the same wireless network.
Therefore, the correct answer is C - "Avoid Persistent Non-WiFi Interference".
