Which requirement does a restricted area normally have, even though physical barriers are not mandated?

• A. Clearly defined perimeters
• B. CCTV surveillance
• C. A guard post is required
• D. The restricted area must be located in a separate building

Answer: (A)

A clearly defined perimeter marks the boundary of the area that requires safeguarding, which is essential for enforcing access controls even when there are no mandatory physical barriers. This boundary lets personnel know where authorization is needed, where to verify credentials, and where accountability and incident response apply. While surveillance or a guard post can enhance security, they aren’t required, and the restricted area doesn’t have to be in a separate building—the important element is that the limits of the area are defined so protection measures can be properly applied.
