Q91. An engineer has been noticing the power settings on several of the office APs change from day to day ever since two more APs were installed. After logging into the WLC, the engineer verifies that the power levels on 4 of the 802.11n radios are fluctuating up and down. What is the reason for this?
A. The controller has the APs in H-REAP mode and are on a Layer 2 connection instead of Layer 3.
B. The RRM has revealed a bad survey and is attempting to power down some of the radios to make up for it.
C. The WLC has created temporary coverage holes while stepping through power levels for some of the APs.
D. Several APs have high levels of overlapping coverage in the same area and the WLC is using RRM to correct the cell sizes AP coverage.
Answer: D

Q96. A lightweight AP has been deployed in local mode in a network that consists of 10 wireless LAN controllers in a single mobility group. The AP has been configured to use primary, secondary, and tertiary Cisco WLCs. Due to a major power failure, all those Cisco WLCs are unavailable.
Which step does the AP take next?
A. The AP reboots and repeatedly attempts to join the configured primary, secondary, and tertiary Cisco WLCs in that order. The process continues until one of the configured Cisco WLCs is available.
B. The AP attempts to join a Cisco WLC configured as a master controller.
C. The AP attempts to join the Cisco WLC that has the greatest capacity available.
D. The AP state transitions to AP Fallback Mode and continues to provide limited WLAN services (that is, no new client authentications) until a Cisco WLC is available.
