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.

A. Antenna power is a relative value reference to dBi.
B. LWAPP allows encrypted communications between lightweight access points and WLAN  controllers.
C. Characteristics of antennas are directionality， gain， and polarization.
D. Power over Ethernet （PoE） is only available when a WLAN controller is integrated into the  network.
E. The WLAN solution Engine （WLSE） is used to control lightweight access points.
F. One of the advantages of the lightweight WLAN solution is that the devices act indepently.

A. The access point has broadcast too many SSIDs.
B. The wireless client has missed too many beacons from the access point.
C. The maximum data retry count， initiated by the wireless client， is exceeded.
D. The wireless client has reduced the data rate.
E. The access point has requested client reauthentication.
F. The wireless client has missed too many IAPP （Inter Access Point Protocol） updates.
