The technician that handles the wireless networks notices that the particular AP has a poor air quality value. The technician uses the CLEAN AIR tab to further investigate and notices that there is an active interferer listed that has a duty cycle of 100%. What should the technician do next?

Reboot the AP.
Track down the offending device that is using the particular frequency causing the interference.
Use the EVENT LOG tab to monitor clients as they attempt to join the wireless network.
Use a different VLAN for that particular AP.

Explanation: When an AP is an issue, one of the best places to start is the WLC GUI. A particular AP can be selected, and the performance summary shows an overall view of the resources being used, clients, and the status of a particular AP. On the CLEAN AIR tab, the duty cycle shows the percentage of time the offending device is transmitting. A duty cycle value of 100% means the offending device can affect the channel all the time. The technician should track down the offending device or select a different RF channel for the AP.
