An AP is receiving 802.11 packets on its 802.11a radio with an RSSI value of -77 dBm. The current AP is part of an AP group that has been assigned an RF profile with RX-SOP set to Medium for 802.11a. Which action does the AP take with the packets?
Frames are decoded by the 2.4 GHz radio.
All frames are classified as non-Wi-Fi frames and are not decoded by the 2.4 GHz radio.
Frames are decoded by the 5 GHz radio.

A customer has restricted the AP and antenna combinations for a design to be limited to one model integrated antenna AP for carpeted spaces and one morel external antenna AP, with high gain antennas for industrial, maintenance, or storage areas. When moving between a carpeted area to an industrial area, the engineer forgets to change survey devices and surveys several APs. Which strategy will reduce the negative impact of the design?
Deploy unsurveyed access points to the design.
Increase the Tx power on incorrectly surveyed access points.
Deploy the specified access points per area type.
Resurvey and adjust the design.

A wireless engineer is getting ready to perform a predictive site survey. The new network needs to support data and voice over wireless. Which two Cisco recommendations should be considered for the design? (Choose two.)
Set -19 dBm of separation between APs on the same channel.
Use the 5 GHz radio band due to 40 MHz bandwidth capability.
Use the 5 GHz radio band due to the 24 non-overlapping channels.
Set the cell boundary to -67 dBm.
Set the cell overlap to 15%

A network administrator of a global organization is collapsing all controllers to a single cluster located in central Europe. Which concern must be addressed?
Some channels may not be available consistently across the organization.
Different RF policies per office are not available in this configuration.
Syslog must be configured to the time-zone of the NMS platform.
Centralized controllers cannot uniformly authenticate global users.

Multiple WLCs are implemented in a high-availability configuration in a mobility group. APs are deployed with only a primary controller assigned. By default, which mobility group member controller do the orphaned APs join in the event of a failed controller?
controller with the most available AP free license capacity
controller with the lowest percent of associated APs per license capacity
controller with the least CPU utilization over the last reporting period
controller with the least number of associated APs
