What must you do before managing your Intune deployment using Active Directory?

Setting Intune as your Mobile Device Management Authority is a crucial step before managing your Intune deployment with Active Directory. This configuration allows Intune to take control over the devices and manage them according to the policies you set, ensuring that the Mobile Device Management (MDM) features of Intune are fully operational.

By making Intune the MDM authority, you enable the platform to interact with your Active Directory environment, apply security policies, deploy applications, and manage users effectively. This step is foundational because without designating Intune as the authority, the integration with Active Directory and device management functionalities will not be fully operational.

The other options, while potentially important in different scenarios, do not specifically address the requirement to use Intune with Active Directory. Installing Windows Server 2016 is not necessary for an Intune environment, as Intune operates primarily in the cloud. Verifying your domain ownership may be required for some configurations but does not directly enable MDM. Finally, configuring user roles and permissions is a subsequent step that benefits from having Intune set up as the MDM authority first.
