Which statement best describes the difference between Azure Active Directory (AAD) and Azure Active Directory Domain Services (AADDS)?

The correct statement emphasizes that Azure Active Directory Domain Services (AADDS) includes support for groups and organizational units (OUs), which are not features of the core Azure Active Directory (AAD).

Azure Active Directory is primarily a cloud-based identity and access management service, designed for managing users and their access to resources in cloud applications. It supports some group functionality, but it does not implement traditional Active Directory features like OUs, which are used to organize users and resources hierarchically in a domain.

In contrast, Azure Active Directory Domain Services provides managed domain services such as domain join, group policy, and LDAP. It allows for the organization of users into groups and OUs, which facilitates management and deployment of resources in environments that require a more Active Directory-like structure. This capability is essential for businesses that want to retain some of the traditional Active Directory functionalities in a cloud environment, making AADDS a distinct solution that complements Azure Active Directory.
