Exam 350-401 topic 1 question 852 discussion

It's not A, "Enable the Avoid Persistent Non-WiFi interference option," because this option, while it does make the system aware of persistent non-WiFi interference, doesn't necessarily prompt an immediate channel change. This setting helps the system to recognize and avoid areas of persistent interference when making decisions on channel assignments during its regular update intervals, rather than triggering an immediate response to interference. Option C, "Enable the Event Driven RRM," is more directly involved in making real-time adjustments to the RF environment, including immediate channel changes in response to detected interference. This is why C is the more effective choice for resolving the issue described, as it actively and dynamically responds to interference detected by Cisco CleanAir.

A - prevents continued interference from non-Wi-Fi devices, but it does not force the AP to switch channels automatically. C - allows the AP to switch channels automatically based on interference events.

C is correct

i will go with A. it makes more sense

This option allows the AP to avoid channels with persistent non-Wi-Fi interference. By enabling this option, the AP can dynamically adjust its channel selection to avoid channels experiencing significant interference, thus improving the overall performance of the wireless network.

I'm pretty sure A is correct. Keep in mind the key words "non-wifi interference". EDRRM would be more directed at congested airspace with other WIFI signals. And adjusting the sensitvity of DCA is just making channel selection a little more paranoid.

Answer C

Answer C https://www.cisco.com/c/en/us/td/docs/wireless/controller/9800/16-12/config-guide/b_wl_16_12_cg/cisco-cleanair.html

I guess the answer is correct Event Driven RRM (ED-RRM) is a feature that allows an AP in distress to bypass normal RRM intervals and immediately change channels.
