What does role-based access control in Azure enable?

1. It allows unlimited access to all resources.

2. It defines permissions for user and group roles.

3. It provides automatic resource provisioning.

4. It creates isolated environments for application testing.

The correct answer is: It defines permissions for user and group roles.

Role-based access control (RBAC) in Azure is a crucial feature that helps organizations manage access to resources securely and efficiently. By defining permissions for user and group roles, RBAC allows administrators to assign specific roles to users or groups that contain specific permissions to perform various tasks. This ensures that individuals only have access to the Azure resources necessary for their job functions, enhancing security and compliance. In Azure, roles can be assigned at different scopes, such as at the subscription, resource group, or individual resource level. For instance, a user assigned the "Reader" role can view resources but cannot modify them, while a user with the "Contributor" role can create and manage resources but may not have permissions to modify access control. This structured approach means that organization can enforce the principle of least privilege, whereby users are granted only the access they require to perform their jobs, thus reducing potential security risks associated with accidental changes or unauthorized access to sensitive data. The other choices don't align with the fundamental concept of RBAC. Access to resources isn't unlimited; it is specifically controlled and limited based on defined roles. RBAC does not automatically provision resources; that function is usually part of deployment processes rather than access control. Additionally, while Azure provides capabilities for creating isolated
