Correct answer: A. Azure Active Directory

Azure Active Directory (Azure AD) is the core identity and access management service in Microsoft 365, enabling single sign-on for users across all connected Microsoft 365 services.

Why the other options are wrong

  • B. Microsoft Purview focuses on data governance, compliance, and risk management.
  • C. Microsoft Intune is for endpoint management and mobile device management, not primary identity management.
  • D. Microsoft Defender is a suite of security products for threat protection, not identity management.

Azure Active Directory (Azure AD)

Microsoft's cloud-based identity and access management service, which helps employees sign in and access resources.

  • Provides single sign-on (SSO) for Microsoft 365 and other cloud apps.
  • Manages user identities, groups, and access permissions.
  • Is the backbone for authentication and authorization in Microsoft 365.

Memory trick: Azure AD is the 'Access Door' to everything in Microsoft 365.
