Arrange the three security areas from least restricted to most restricted.

• A. OCA, PA, VA
• B. VA, PA, OCA
• C. PA, OCA, VA
• D. OCA, VA, PA

Answer: (A)

Access controls are layered, with restrictions tightening as you move inward toward more sensitive operations. The outermost area, Outside Controlled Area, is the least restricted and typically allows broader public access with basic screening. The next zone, Protected Area, requires authorization to enter and has more stringent controls. The innermost zone, Very Restricted Area, has the strictest access, with in-depth authorization, escorts, and enhanced security measures. Because the design is to progressively increase security toward the core, the correct order from least to most restricted is Outside Controlled Area, Protected Area, and Very Restricted Area. This matches the chosen arrangement.
