Question

A network engineer uses Cisco Catalyst Center Assurance to investigate user complaints in a warehouse. The wireless Client Health dashboard shows several clients with a poor health score, and the client 360 view flags them during the 'Onboarding' phase with the RF metric indicating a high noise floor of -78 dBm on the 2.4 GHz band. AP and WLC device health scores are all green, and RADIUS authentication times are normal. Which conclusion is best supported by this Assurance data?

Accepted Answer

The clients are experiencing RF interference, and the onboarding delay is caused by association/DHCP issues aggravated by the poor signal-to-noise environment, not by infrastructure device or authentication failures

Answer

The WLC is overloaded, since a poor client health score always indicates a device health problem on the controller

Answer

The RADIUS server is dropping requests, because onboarding-phase failures are exclusively caused by AAA timeouts

Answer

The AP firmware is corrupted, as Assurance only reports a high noise floor when an AP radio driver has crashed
