Microsoft 365 Fundamentals MS-900 Practice Question

Synchronizing user accounts between an on-premises Active Directory and Microsoft Entra ID is the hallmark of a hybrid identity model. In this approach, the authoritative account resides on-premises, a copy is stored in the cloud, and Microsoft Entra Connect keeps both directories in sync. This allows users to sign in with the same username and password to access resources hosted either on-premises or in Microsoft 365. Cloud-only identity stores accounts exclusively in Microsoft Entra ID, while on-premises identity relies solely on Active Directory without cloud copies, and guest/external identity refers to accounts that originate outside the organization.
