Explanation

Explanation

Event Driven RRM (EDRRM) is the feature that allows Cisco CleanAir to trigger an immediate, reactive channel change when significant non-Wi-Fi interference is detected - without waiting for the normal DCA interval cycle. Without EDRRM enabled, CleanAir can detect and report interference via traps, but the AP will not autonomously change channels in response, which is exactly the symptom described.

Why the distractors are wrong:

• Option A (Avoid Persistent Non-Wi-Fi Interference) addresses persistent interferers by keeping the channel change in place after EDRRM acts - it is a companion feature, but enabling it alone won't trigger the channel change.
• Option B (DCA Sensitivity High) makes the standard DCA algorithm more sensitive to interference during its scheduled intervals, but does not enable real-time, event-driven channel changes.
• Option D (Disable Avoid Foreign AP Interference) relates to interference from neighboring APs, not non-Wi-Fi interferers, and is completely unrelated to the issue.

Memory Tip: Think of the relationship as CleanAir = the eyes, EDRRM = the legs - CleanAir sees the interference and sends the trap, but EDRRM is what makes the AP move (change channels) immediately in response.
