   A hospital has a WLC-managed WLAN. The WLC CleanAir identifies a persistent 'Video Camera' interferer on channel 6. The interferer is in a patient room and cannot be moved. The hospital also has a critical telemetry system that must remain on channel 6. The WLAN uses RRM. What is the best action to maintain both the telemetry system and WLAN performance?

   • AAllow RRM to move the telemetry system to another channel automatically.
   • BExclude channel 6 from RRM's channel list and manually assign affected APs to other channels.
   • CIncrease the transmit power of APs on channel 6 to overcome the interferer.
   • DDisable CleanAir on the affected APs to stop the interferer from affecting RRM decisions.

   A factory uses a WLC-managed WLAN. The WLC CleanAir shows a 'Motor' interferer on channel 1. The motor is part of a conveyor belt that cannot be stopped. The factory uses 2.4 GHz-only scanners. What should you do to maintain scanner connectivity?

   • AIncrease the transmit power of the APs.
   • BDisable the 2.4 GHz radio on the APs and use 5 GHz only.
   • CMove the APs near the conveyor belt to channel 6 or 11.
   • DEnable RRM to automatically adjust channels.

   A school district uses Cisco Catalyst Center for wireless assurance. The RF analytics dashboard shows a high level of interference in the gymnasium, but the WLC's CleanAir does not show any non-Wi-Fi interferers. The administrator suspects a new wireless microphone system. What should the administrator do to confirm the source?

   • ALook at the 'AP 360' view to see the AP's current channel and power settings.
   • BUse the 'RF Spectrum' page in Catalyst Center to view the spectral data for the gymnasium APs.
   • CReview the 'Network Health' summary to see if the overall network is degraded.
   • DCheck the 'Client Health' for clients in the gymnasium to see if they are experiencing poor performance.

   A university uses Cisco Catalyst Center for wireless assurance. During a large lecture, the Wi-Fi becomes sluggish. Catalyst Center's RF analytics shows a high number of Bluetooth interferers on 2.4 GHz. The lecture hall uses a Bluetooth-based audience response system. The university cannot disable the response system. What should you do to improve Wi-Fi performance?

   • AConfigure the WLAN to prefer 5 GHz band for capable clients and keep 2.4 GHz for legacy devices.
   • BMove the access points to 5 GHz only and disable 2.4 GHz radios.
   • CEnable CleanAir's 'Bluetooth' classification and set the APs to avoid channels with high Bluetooth activity.
   • DUse Catalyst Center's RRM to move APs to less-congested 2.4 GHz channels.
