A、 An AP that has been upgraded from an autonomous AP to lightweight AP will only function in  conjunction with a Cisco Wireless LAN controller.

B、 LWAPP increases the amount of processing within the APs， enabling them to support filtering  and policy enforcement features.

C、 WLAN controllers provide a single point of management.

D、 Lightweight APs require local configurations using local management.

E、 Real time events such as authentication， security management， and mobility are handled by the  lightweight AP.

F、 Autonomous APs receive control and configuration information from a WLAN controller.
