Which of the following are the four role types in Role-Based Access Control (RBAC)?

The four role types in Role-Based Access Control (RBAC) within the context of Illumio Core are indeed Global Viewer, Global Policy Object Provisioner, Global Administrator, and Global Organization Owner.

The Global Viewer role allows users to see the organization's configurations and statuses without the ability to make changes. This ensures that users can access necessary information while implementing a layer of security by restricting their permission to alter or create configurations.

The Global Policy Object Provisioner is responsible for creating and managing policies across various workloads and environments within the organization, highlighting the importance of policy management in maintaining security and compliance.

The Global Administrator role has comprehensive control over the entire setup and can make major changes, making them critical in organizational governance.

Lastly, the Global Organization Owner embodies the role with the highest level of authority, overseeing all organizational aspects and ensuring that strategic decisions align with business objectives. They serve as the ultimate authority in managing access and maintaining the integrity of the access control model.

Other options do not represent the established roles in Illumio's RBAC system and instead present combinations that do not exist or are not recognized within the RBAC framework, thus making them incorrect.
