Question 852

Refer to the exhibit. An engineer is troubleshooting an issue with non-Wi-Fi interference on the 5-GHz band. The engineer has enabled Cisco CleanAir and set the appropriate traps, but the AP does not change the channel when it detects significant interference. Which action will resolve the issue?

    Correct Answer: C

    The correct action is to enable the Event Driven Radio Resource Management (EDRRM) option. EDRRM allows the Access Point (AP) to make immediate adjustments to the radio frequency environment, including changing channels in real-time in response to detected interference. This is crucial when dealing with significant interference as it prompts the system to act dynamically rather than waiting for the next scheduled channel reassignment interval. Therefore, enabling EDRRM will resolve the issue of the AP not changing the channel despite detecting significant non-Wi-Fi interference.

Discussion
supershysherlockOption: C

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.

studying_1Option: C

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.

DCA sensitivity to high https://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/8-3/b_RRM_White_Paper/dca.html

Alondrix

Your link to the White Paper indicates the channel can be changed with DCA to to high, medium, or low. I think the correct answer is as stated, RRM per the same link. ED-RRM is not directly related to RRM, but will cause channel changes if invoked.

SeMo0o0oOption: C

C is correct

SeMo0o0oOption: A

i will go with A. it makes more sense

SeMo0o0o

after another chat with GPT i decided to go with C

Osama_anwarOption: A

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.

HammyHamsterOption: A

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.
