Which permission level allows full control over a shared resource?

The permission level that allows full control over a shared resource is Full Control. This level provides users with all available permissions on that resource, enabling them to both access and modify the content, as well as manage permissions and settings. Specifically, users with Full Control can perform actions such as creating, deleting, and renaming files or folders, in addition to changing security settings for other users. This level of permission is crucial in scenarios where a user needs complete authority over a resource, ensuring they can manage all aspects of that resource without restrictions.

In contrast, other permission levels such as Read, Modify, and Write have more limited capabilities. Read only allows users to view content without making any changes. Modify enables users to make changes but does not include permission to alter security settings or delete the resource. Write allows users to add or change content but does not grant them the permission to read existing content if combined with restrictive settings. Therefore, Full Control is the only permission level that encompasses all these functionalities, making it the most powerful and comprehensive option.
