Which post provides surveillance over the boundary of restricted areas?

• A. Close Boundary Sentry (CBS)
• B. External SRT (ESRT)
• C. Immediate Visual Assessment Sentry
• D. Alarm Monitor

Answer: (A)

Watching the boundary of restricted areas requires a post whose primary duty is direct, continuous observation along the edge. The Close Boundary Sentry is set up for exactly that role: stationed right at the boundary, it maintains sightlines along the fence, gates, and approaches, detects any unusual activity, and can immediately report or respond to potential breaches. This proactive presence serves as both a deterrent and an early warning, which is what boundary surveillance demands.

The other posts serve different functions. An External SRT focuses on threats and coordination outside the boundary, not on constant boundary monitoring. An Immediate Visual Assessment Sentry is typically called to quickly evaluate a developing situation after an alert, rather than providing ongoing boundary surveillance. An Alarm Monitor deals with alarm systems and signals, not the continuous visual watch along the boundary.
