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.

A. The LAP will send out a DNS request. In return， the DNS server will provide the WLC domain  name.
B. The LAP will send out a Layer 3 LWAPP discovery request to the WLC on the wireless network. 
C. The LAP will send out a DHCP request. In return， the DHCP server will provide the IP  addresses for the LAP and the WLC.
D. The LAP will send out a Layer 2 LWAPP discovery request to the WLC on the wireless network.

A. It indicates that the client adapter is not associated to an access point or another client.  
B. It indicates that the radio of the client adapter is disabled.
C. It indicates that the client adapter is associated to an access point or another client， but the  user is not EAP authenticated.
D. It indicates that the client adapter is associated to an access point or another client， that theuser is authenticated if the client adapter is configured for EAP authentication， and that the signal  strength is poor.
E. It indicates that the client adapter is associated to an access point or another client， that the  user is authenticated if the client adapter is configured for EAP authentication， and that the signal  strength is fair.
F. It indicates that the client adapter is associated to an access point or another client， that the  user is authenticated if the client adapter is configured for EAP authentication， and that the signal  strength is excellent or good.
