A.It indicates that the radio of the client adapter is disabled
B.It indicates that the client adapter is not associated to an access point or another client
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 the user is authenticated if the client adapter is configured for EAP authentication， and that the signal strength is excellent or good
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 poor
Refer to the exhibit. The command spanning-tree guard root is configured on interface Gi0/0 on both switch S2 and S5. The global configuration command spanning-tree uplinkfast has been configured on both switch S2 and S5. The link between switch S4 and S5 fails. Will Host A be able to reach Host B？（）
A.Yes. Traffic can pass either from switch S6 to S3 to S2 to S1， or， from switch S6 to S5 to S2 to S1
B.No. Traffic will pass from switch S6 to S5 and dead-end at interface Gi 0/0
C.No. Traffic will loop back and forth between switch S5 and S2
D.Yes. Traffic will pass from switch S6 to S3 to S2 to S1
E.No. Traffic will either pass from switch S6 to S5 and dead-end， or traffic will pass from switch S6 to S3 to S2 and dead-end
Refer to the exhibit. Which Virtual Router Redundancy Protocol （VRRP） statement is true about the roles of the master virtual router and the backup virtual router？（）
