What is the maximum number of roles allowed under Role Based Access?

• A. 4
• B. 6
• C. 8
• D. 10

Answer: (C)

Role Based Access creates a set of permissions by assigning roles, and a user can hold multiple roles to cover different tasks. The system sets a limit on how many roles a user can have to keep management straightforward and the permission structure auditable. Eight roles give enough flexibility to separate common tasks (such as operator, supervisor, maintenance, diagnostics, security, trainer, guest, and admin) without creating an unwieldy web of permissions. If you used fewer than eight, you’d either stack too many duties into one role or fail to cover distinct responsibilities. Going higher than eight makes administration and auditing more complex and increases the chance of unintended permission overlaps. So, eight is the practical maximum in this context.
