Which access control function will not allow entry into a secure area until there has been a valid read into the area by a supervisor?

• A. Supervisor first
• B. Biometric only
• C. Dual authentication
• D. Card plus PIN

Answer: (A)

The function being tested is supervisory gating of access: a supervisor must perform a valid read-in before the area can be entered. This requirement ensures oversight and accountability, because entry cannot proceed until someone in authority has activated the system. Once the supervisor has authenticated, normal users can enter, and the action is auditable. Biometric only relies on an individual’s biometric credential, which doesn’t enforce supervisor involvement. Dual authentication requires two factors but doesn’t inherently require a supervisor’s read-in. Card plus PIN is still a single user’s credential set and likewise doesn’t mandate supervisor initiation.
