問題2
If an online AP on the active AC is added offline to the standby AC, the AP status is displayed as fault on the standby AC. In this case, you can run the undo hsb enable command to disable the HSB function in the HSB group view on the standby AC, and then run the HSB enable command to enable the HSB function. In this way, information on the active and standby ACs is the same and the AP status is displayed as standby on the standby AC.

A. FALSE

B. TRUE

正確答案: B
