Exam 300-430 topic 1 question 49 discussion

Should be C correct Check the Avoid Non-802.11a (802.11b) Noise check box to cause the controller’s RRM algorithms to consider noise (non-802.11 traffic) in the channel when assigning channels to lightweight access points, or uncheck it to disable this feature. For example, RRM may have access points avoid channels with significant interference from nonaccess point sources, such as microwave ovens. The default value is selected. Check the Avoid Persistent Non-WiFi Interference check box to configure the controller to stop ignoring persistent non-Wi-Fi interference in new channel calculation. The persistent non-Wi-Fi interference is considered during the metric calculation for channels. https://www.cisco.com/c/en/us/td/docs/wireless/controller/8-6/config-guide/b_cg86/radio_resource_management.html

To prevent Radio Resource Management (RRM) from changing channels due to non-802.11 interference, the Avoid Persistent Non-WiFi Interference feature must be enabled. Here’s why: Avoid Persistent Non-WiFi Interference: This feature allows RRM to ignore non-802.11 interference (e.g., from microwaves, cordless phones, or Bluetooth devices) when making channel decisions. It ensures that RRM does not unnecessarily change channels in response to transient or persistent non-WiFi interference. Why it’s the solution: If RRM keeps changing channels due to non-802.11 interference, it can disrupt network performance. Enabling this feature ensures that RRM focuses on optimizing channels based on WiFi-related factors rather than non-WiFi interference.

I actually got this question on my last exam verbatim and yes, the question is written incorrectly. It should be "disable" but either way, C is correct.

the question is wrong...should be "disable" , not "to enable" We dont want to change channel due to interferences

provided answer is correct https://www.cisco.com/c/en/us/td/docs/wireless/controller/9800/configure-guide/b_wi_16_10_cg/radio-resource-management.html
