  C. The AP accesses the address of the AC as the primary and standby AC virtual address.
  D. Any address configured in the AC can be
  C. The AP accesses the address of the AC as the primary and standby AC virtual address.

• Question 392:

  An engineer sets the synchronization type of the Agile Controller to be synchronized by group. However, after synchronization, there is no information on the Controller. Check the AD directory server and find that the directory server is normal. User information and user group information are normal. What is the possible cause of this phenomenon?

  A. The synchronization mode of the Agile Controller is configured to automatically synchronize.
  B. Agile Controller synchronization range configuration error
  C. The data structure mapping configuration of the Agile Controller authentication source is incorrect.
  D. The Agile Controller does not have any OU filters configured.
  B. Agile Controller synchronization range configuration error
  C. The data structure mapping configuration of the Agile Controller authentication source is incorrect.

• Question 393:

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

• Question 394:
