Azure RBAC is designed to provide fine-grained access management by allowing the definition of custom roles with specific permissions that match the needs of different roles or departments within an organization. This approach supports the principle of least privilege by ensuring users have only the access they need to perform their job functions. Additionally, Azure RBAC integrates with Azure's compliance and auditing features, enabling organizations to track access and changes to resources for security and regulatory purposes. The option E is also correct because Azure RBAC offers a range of built-in roles that can be used as is or slightly modified to fit specific needs, providing flexibility and reducing the overhead of creating entirely custom roles from scratch.
