Which two features or capabilities are valid options for both an Autonomous WLAN solution and a  Lightweight WLAN solution？ （）

A. The access point will attempt to download an encryption key from the nearest wireless server.
B. The access point makes several attempts to get an IP address from the DHCP server. If the  access point does not receive an address， it assigns itself the IP address 10.0.0.1 for 5 minutes.
C. The access point will attempt to connect to the nearest wireless server using LEAP  authentication.
D. The access point requests an IP address from the DHCP server. If the access point does not  receive an address， it continues to send requests indefinitely.
E. None of the other alternatives apply

A. In ad hoc mode， the Independent Basic Service Set （IBSS） is a framework in which mobile  clients connect directly without an intermediate access point.
B. In Infrastructure mode， the Basic Service Set （BSS） is a framework in which mobile clients use  a single access point for connecting to each other or to wired network resources.
C. In Infrastructure mode， the Extended Services Set （ESS） is a framework in which two or more  Basic Service Sets are connected by a common distribution system （DS）.
D. In Infrastructure mode， the Independent Basic Service Setet （IBSS） is a framework in which  mobile clients connect directly without an intermediate access point.
E. In ad hoc mode， the Basic Service Set （BSS） is a framework in which mobile clients use a  single AP for connecting to each other or to wired network resources.
F. In ad hoc mode， the Extended Services Set （ESS） is a framework in which two or more Basic  Service Sets are connected by a common distribution system （DS）

A. In the autonomous access point solution， control is provided by the WLAN controller.
B. In the lightweight access point solution， WLAN management is provided by the WLAN Control  System （WCS）.
C. In the autonomous access point solution， control is provided by the WDS （Wireless Domain  Services）.
D. Cisco Aironet autonomous access points cannot be supported by the Cisco Unified Wireless  Network.
E. Ii the lightweight access point solution， WLAN management is provided by the WLAN Solution  Engine （WLSE）.
F. Cisco Aironet lightweight access points cannot be supported by the Cisco Unified Wireless  Network.
