   A manufacturing plant uses a WLC with CleanAir. The RF environment has a persistent interferer on channel 11 that is classified as 'unknown'. The plant has a critical production system that must remain on channel 11 for compliance reasons. The administrator wants to mitigate the impact on other devices without changing the channel of the critical system. What is the best action?

   • AIncrease the transmit power of the APs to overcome the interference.
   • BDisable CleanAir on the affected APs to prevent the unknown interferer from causing false alarms.
   • CUse CleanAir's 'Interferer' details to identify the source of the unknown interferer and then physically remove or shield it.
   • DEnable 'Event-Driven RRM' on the WLC to automatically move APs to a cleaner channel when the interferer is detected.

   A hospital uses a WLC-managed WLAN. The WLC CleanAir identifies a 'Continuous Wave' interferer on channel 11. The interferer is a faulty medical pump. The hospital cannot replace the pump immediately. The WLAN also has a critical patient monitoring system that must use channel 11. What is the best action to protect the patient monitoring system while maintaining WLAN performance?

   • AExclude channel 11 from RRM's channel list and manually assign APs to other channels.
   • BDisable CleanAir on the affected APs.
   • CIncrease the transmit power of APs on channel 11.
   • DAllow RRM to move the patient monitoring system to another channel.

   A hotel's wireless network has a recurring interference problem in the conference center. The WLC's CleanAir identifies a 'continuous' interferer on the 5 GHz band. The administrator suspects a new wireless camera system installed by the events team. What is the most appropriate first step to confirm the source?

   • AChange the channel plan to use only UNII-1 channels, which are less likely to be affected by the camera system.
   • BDisable the 5 GHz radios on the APs in the conference center to force clients to use 2.4 GHz.
   • CUse the WLC's CleanAir to locate the interferer by triangulating the signal strength from multiple APs.
   • DIncrease the AP transmit power to overcome the interference from the camera system.

   A retail chain uses Cisco Catalyst Center for wireless assurance. Store managers report poor Wi-Fi in the stockroom. Catalyst Center's RF analytics shows a high number of 'Other' interferers on 5 GHz. You need to identify the physical source of the interference. Which Catalyst Center feature should you use?

   • AThe RF Spectrum dashboard, which shows real-time FFT plots for each AP.
   • BThe Client 360 view, which shows which clients are affected by the interferer.
   • CThe Location Analytics map, which shows the estimated position of the interferer based on AP signal strength.
   • DThe Interferer Details page, which lists interferer type, severity, and affected APs.
