Which surveillance technique uses detectors placed around and throughout a specific high-value target to provide detection and early warning of a CBRN attack?

• A. Critical Node
• B. Area Array
• C. Continuous
• D. Periodic

Answer: (A)

Detecting a CBRN threat by placing detectors around and throughout a single high-value target creates a protective surveillance framework centered on that asset, providing early warning before an attack fully impacts the target. This approach—protecting and monitoring a critical asset with a ring of sensors—allows rapid detection and response, minimizing exposure and damage. That focus on a specific valuable node is why the correct choice fits best. An area-wide sensor layout would emphasize broad coverage of a larger zone rather than concentrated protection of one target. Meanwhile, terms describing how often monitoring occurs (continuous or periodic) don’t address where the detectors are deployed or the defensive emphasis on safeguarding a particular asset.
