   A manufacturing plant uses Cisco Catalyst Center for network assurance. The RF analytics dashboard shows a persistent interferer in the assembly area, but the administrator is unsure if it is a Wi-Fi device or a non-Wi-Fi source. The plant has a mix of legacy 2.4 GHz devices and newer 5 GHz equipment. What is the best way to determine the nature of the interferer?

   • ACheck the 'Interferer' details in Catalyst Center, which provides the classification (e.g., Bluetooth, microwave, or unknown) and the affected channel.
   • BLook at the 'Network Health' summary to see if the overall network is degraded, which would indicate a serious interferer.
   • CUse the 'AP 360' view to see the AP's current channel and power settings, which may reveal if the AP is on a congested channel.
   • DReview the 'Client Health' score for clients in the assembly area, which indicates if they are experiencing poor performance due to interference.

   A logistics company uses Cisco Catalyst Center for wireless assurance. The RF analytics dashboard shows a persistent interferer in the loading dock area. The administrator wants to know if the interferer is from a specific device or from an external source. Which Catalyst Center feature should be used to get the most detailed diagnostic information?

   • AThe 'AP 360' view, which shows the AP's current channel and power settings.
   • BThe 'Interferer' details page, which provides classification, severity, and affected channels.
   • CThe 'Network Health' summary, which shows the overall health of the network.
   • DThe 'Client 360' view for a client in the loading dock, which shows the client's RSSI and SNR.

   A small office uses a WLC-managed WLAN. Employees complain about slow Wi-Fi in the conference room. The WLC CleanAir shows a 'Bluetooth' interferer with high severity. The conference room has a Bluetooth speaker that is always on. The office manager wants to keep the speaker. What should you do to improve Wi-Fi for the conference room?

   • ADisable the 2.4 GHz radio on the AP.
   • BMove the AP to a different 2.4 GHz channel.
   • CEnable band steering to push capable clients to 5 GHz.
   • DIncrease the AP's transmit power to overcome the Bluetooth signal.

   When using the WLC to manage RF interferers, which action can an administrator take to mitigate an identified non-Wi-Fi interferer?

   • AReboot the access point
   • BChange the AP transmit power to maximum
   • CDisable the interferer's SSID
   • DAdjust the channel plan to avoid the interferer's frequency

   A retail store's wireless network is experiencing intermittent drops near the loading dock. The WLC's CleanAir identifies a 'microwave oven' interferer on channel 11. The store manager says the microwave is used only during lunch hours. The administrator wants to minimize the impact on the store's handheld scanners, which are used throughout the day. What is the most effective configuration?

   • AIncrease the transmit power of the AP to overcome the interference from the microwave.
   • BEnable 'Event-Driven RRM' on the WLC so that the AP dynamically moves to a cleaner channel when the microwave is detected.
   • CSet the WLC to use 'CleanAir' to automatically switch the affected AP to channel 1 during lunch hours.
   • DManually assign the AP to channel 6 and disable CleanAir to prevent the AP from changing channels during the day.
