Which two actions should you perform?

You plan to use Password Sync on your DirSync Server with Azure Active Directory (Azure AD) on your
company network. You configure the DirSync server and complete an initial synchronization of the users.
Several remote users are unable to log in to Office 365. You discover multiple event log entries for “Event ID
611 Password synchronization failed for domain.”
You need to resolve the password synchronization issue.
Which two actions should you perform? Each correct answer presents part of the solution.

A.
Restart Azure AD Sync Service.

B.
Run the Set-FullPasswordSync Power Shell cmdlet.

C.
Force a manual synchronization on the DirSync server.

D.
Add the DirSync service account to the Schema Admins domain group.

Explanation:
The Set-FullPasswordSync Power Shell cmdlet resets the password sync state information forcing a full sync
the next time the service is restarted. Then we need to restart the service to initiate the sync.
