Which definition correctly describes RBAC?

• A. RBAC: a method of regulating access to computer or network resources
• B. RBAC: The newest tool for performing day to day tasks since server 2008
• C. RBAC: Provides administrators the ability to manage users and computers
• D. RBAC: Allows administrators to manage server roles from a Windows workstation

Answer: (A)

RBAC is a way to control access to resources by assigning people to roles and giving each role a defined set of permissions. Access decisions come from the role a user has, so individuals gain the necessary rights through their role rather than being granted permissions one by one. This makes security and administration easier: when someone’s job changes, you update their role rather than reconfiguring many permissions. The description that fits best is that RBAC is a method of regulating access to computer or network resources. The other statements focus on tools, day-to-day task performance, or administrative capabilities rather than the access-control model itself.
