A new lightweight access point （LAP） has been installed in the Company WLAN.  Which two  statements correctly describe the association process between this LAP and a WLAN controller？ （）

• A、 An access point will search for a controller using a broadcast address if using LWAPP Layer 2  and a unicast address if using LWAPP Layer 3 mode.
• B、 If multiple wireless controllers are detected by an access point， the controller with the fewest  associated access points is chosen to associate with.
• C、 In order to associate in Layer 3 mode， the access point must have been preconfigured with an  IP address.
• D、 Once an access point associates with a controller in LWAPP Layer 3 mode， it receives an IP  address from the controller.
• E、 An access point first searches for a controller in LWAPP Layer 2 mode. If the search is not  successful， the access point then attempts to locate a controller in LWAPP Layer 3 mode.
• F、 If multiple wireless controllers are detected by an access point， all of them will be used and  traffic will be load balanced.
