A. Dynamic load balancing solves the problem of limited number of members in static load balancing

B. The number of dynamic load balancing members is the same as the number of static load balancing members.

C. Each member of the dynamic load balancing equalization group is automatically configured or can be a different frequency band.

The following is wrong about enabling the HSB backup group?

A. The HSB backup group can be enabled directly in the global mode.

B. Before the active and standby ACs go online, the AP needs to complete offline addition on the active and standby ACs.

C. If the AP has been added to the active AC and the AP is added to the standby AC, the AP status on the standby AC is displayed as fault.

D. After the HSB backup group is enabled, the related configuration of the HSB backup group takes effect. The HSB backup group notifies the corresponding service module to process when the status changes.
