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.
Refer to the exhibit.
What type of message will be used by the lightweight access point （LAP） in an attempt to locate the wireless LAN controller （WLC）？ （）
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.
