Which statement correctly describes the procedure for a lightweight AP to successfully establish a connection to a controller?
A . The AP authenticates the received Cisco WLC certificate as valid. The AP then sends its certificate to the controller.
B . The AP sends its certificate to the controller. The AP then authenticates the received Cisco WLC certificate as valid.
C . The AP sends its certificate to the RADIUS server. The AP then authenticates the controller certificate as valid.
D . The AP sends its certificate to the RADIUS server. The AP then authenticates the RADIUS certificate as valid.
E . The AP authenticates the received RADIUS server certificate as valid. The AP then sends its certificate to the RADIUS server.
F . The AP authenticates the received RADIUS server certificate as valid. The AP then sends its certificate to the controller.
Answer: B
Explanation:
The controller will respond to all discovery requests without checking certificates or AP credentials.
However, join requests must have a valid certificate in order to get a join response from the controller. If the LAP does not receive a join response from its choice, the LAP will try the next controller in the list unless the controller is a configured controller (Primary/Secondary/Tertiary).
