Microsoft 365 Certified: Administrator ExpertImplement and manage Microsoft Entra IDEasy

An organization is setting up Microsoft Entra Connect to synchronize identities from its on-premises Active Directory Domain Services (AD DS) to Microsoft Entra ID. They have several Organizational Units (OUs) that contain service accounts and legacy users which should *not* be synchronized to the cloud. You need to configure Microsoft Entra Connect to exclude these specific OUs from synchronization. What is the most efficient way to achieve this?

  1. ADisable the synchronization for the entire domain via PowerShell.
  2. BModify the synchronization rules in Synchronization Service Manager.
  3. CConfigure attribute-based filtering for each user in the OUs.
  4. DUse OU-based filtering during the Microsoft Entra Connect installation wizard.
Show answer & explanation

Correct answer: D. Use OU-based filtering during the Microsoft Entra Connect installation wizard.

The most efficient way to exclude specific OUs from synchronization is to use OU-based filtering during the Microsoft Entra Connect installation wizard. This allows for straightforward selection of OUs to include or exclude.

Why the other options are wrong

  • A. Disabling synchronization for the entire domain is too broad and would prevent all other desired users from synchronizing.
  • B. Modifying synchronization rules is more complex and less efficient for simple OU exclusion during initial setup.
  • C. Attribute-based filtering is for individual users or groups based on attributes, not whole OUs efficiently.

Microsoft Entra Connect OU Filtering

A feature in Microsoft Entra Connect that allows administrators to select which Organizational Units (OUs) from the on-premises Active Directory should be synchronized to Microsoft Entra ID.

  • Configured during initial setup or post-installation.
  • Excludes entire OUs from synchronization.
  • Prevents unwanted objects (e.g., service accounts) from appearing in Microsoft Entra ID.
  • Can be modified later using the Microsoft Entra Connect wizard.

Memory trick: OU filtering: Only Upload Useful OUs.
