Final answer:
The claim that only Azure AD users can be authorized to access Azure resources is false. Azure offers diverse authentication methods and utilizes RBAC to manage access for different identities.
Step-by-step explanation:
The statement that authorization to access Azure resources can be provided only to Azure Active Directory (Azure AD) users is false. Azure allows for a variety of authentication mechanisms and can provide access to resources to users, groups, and even to applications or managed identities that may not be represented as traditional users within Azure AD. Authorization in Azure is managed through role-based access control (RBAC), which can be applied to various identities, not limited solely to individual users within Azure AD.
