A lightweight AP has been deployed in local mode in a network consisting of 10 wireless LAN controllers
in a single mobility group. The AP has been configured to use primary, secondary, and tertiary WLCs. Because of a major power failure, the AP's primary, secondary, and tertiary Cisco WLCs are all unavailable. Which action will be taken next by the AP? A. The AP will attempt to join the Cisco WLC with the greatest amount of available capacity. B. The AP will attempt to join a Cisco WLC configured as a "Master Controller." C. The AP state will transition to AP Fallback Mode and continue providing limited WLAN services (that is, no new client authentications) until a WLC is again available. D. The AP will reboot and repeatedly attempt to join the configured primary, secondary, and tertiary Cisco WLCs in that order. The process will continue until one of the configured WLCs is again available. |
