Microsoft 365 Fundamentals MS-900 Practice Question

The federated identity model allows organizations to keep user authentication on-premises using their existing Active Directory infrastructure. With federation, users authenticate against the on-premises Active Directory, and access to cloud resources is granted based on this authentication. This meets the requirement of continuing to use on-premises authentication while accessing cloud-based services. The synchronized identity model synchronizes user accounts and password hashes to Microsoft Entra ID, but authentication happens in the cloud, not on-premises. Cloud identity involves creating and managing users only in Microsoft Entra ID, without using an on-premises directory. On-premises identity refers to a scenario where all resources are on-premises and does not provide access to cloud-based resources.
