Which item is listed as a component of physical security checks for a restricted area?

• A. Lighting and building color.
• B. Interior decorations and furniture arrangement.
• C. Boundary barrier systems, gates, structures.
• D. Cafeteria services and restrooms.

Answer: (C)

Physical security checks for a restricted area focus on protecting the perimeter and controlling entry points. Perimeter elements like boundary barriers, gates, and the structures that make up the enclosure are key parts of how access is prevented or monitored, since they directly deter and slow unauthorized entry and support controlled admission.

The other items miss the mark because lighting and building color affect visibility or aesthetics but don’t establish the actual secure boundary; interior decorations and furniture arrangement relate to internal space use rather than securing the perimeter; cafeteria services and restrooms are operational facilities not part of perimeter security controls.
