What is a primary advantage of having a Role-Based Access Control (RBAC) system in an enterprise network?

A primary advantage of having a Role-Based Access Control (RBAC) system in an enterprise network is the simplified management of network access permissions. RBAC streamlines the process of granting and managing access rights by assigning permissions based on the roles of users within the organization. This means that rather than managing permissions for each individual user, administrators can manage access by defining roles that correspond to job functions. Each role has specific permissions assigned to it, making it easier to grant, modify, or revoke access rights as employees change positions or as organizational needs evolve. This approach reduces the likelihood of errors, enhances security by ensuring that users only have access to the information and resources necessary for their roles, and can significantly save time in managing permissions across the network.

The other options, while relevant to different aspects of network management, do not capture the core benefit of RBAC. Wireless speed, physical security, and bandwidth control concern different facets of network operation and management that do not directly pertain to how access controls are managed through RBAC.
