A key characteristic of Role-Based Access Control (RBAC) is that access is based on user roles. In RBAC, permissions are assigned to specific roles within an organization instead of directly to individual users. Users are then assigned to these roles based on their job responsibilities, which determines the level of access they have to resources and information.

This method streamlines access management because it allows administrators to easily control permissions by altering role definitions rather than modifying individual user accounts each time a change is needed. It also enhances security and compliance by ensuring users only have access to the data necessary for their roles, thereby minimizing the potential for unauthorized access or data breaches.

The other options describe access mechanisms that do not align with the principles of RBAC. Access based on user location, preferences, or randomness does not provide the structured and role-oriented approach that RBAC embodies. Thus, the focus on roles in RBAC is critical for building an organized and secure access control system.
