Microsoft 365 Administrator Expert MS-102 Practice Question

You administer a hybrid identity environment that uses Microsoft Entra Connect Sync to synchronize an on-premises Active Directory forest to a Microsoft Entra tenant. New users created yesterday in Active Directory are not present in Entra ID. In Synchronization Service Manager on the Azure AD connector, the export step shows several objects with status Error and the message "ConstraintViolationError: attributeValueMustBeUnique (mail)". You need to restore successful synchronization with the least administrative effort. Which action should you perform first?

  • Create a custom Azure AD Connect outbound synchronization rule to stop exporting the mail attribute.

  • Start a full synchronization cycle by running Start-ADSyncSyncCycle -PolicyType Initial on the Azure AD Connect server.

  • Run the IdFix tool against Active Directory and correct any duplicate mail or proxyAddresses values.

  • Enable staging mode on the current Azure AD Connect server and build a new production server for a fresh full sync.
