What technique allows users to be created and managed through an on-premises identity provider?

The correct choice is based on the functionality of directory synchronization. This technique enables organizations to create and manage user identities within an on-premises directory service, such as Active Directory, and synchronize these identities to a cloud-based service. This ensures that users have a consistent identity experience across both on-premises and cloud environments.

Directory synchronization facilitates the management of user accounts, groups, and permissions in a centralized manner, allowing administrators to maintain control over user identity while leveraging cloud services. This approach is particularly beneficial for organizations that wish to have consolidated user management without having to manually create accounts in multiple systems.

Federated identity involves linking identity management systems across different domains, allowing users to authenticate using their credentials from their home organization. While this supports single sign-on capabilities, it does not specifically address the management of identities within an on-premises identity provider.

Cloud identity refers to identity services provided by cloud providers, typically allowing for user account management directly on cloud platforms. This does not inherently involve an on-premises identity provider.

OAuth is an open-standard authorization protocol that allows users to grant third-party access to their resources without sharing passwords. It focuses on authorization rather than identity management and creation.

Understanding the differences in these techniques is critical for effective identity and access management,
