Self-contained sections of Sites or Areas designed to self-seal in case of a breach or catastrophic event are called what?

• A. Armed
• B. Site
• C. Sector
• D. Unit

Answer: (D)

This question tests how the Foundation names modular, self-contained blocks within a site that can seal off during an emergency. These blocks are designed to function independently, so if a breach occurs or a catastrophic event happens, a section can shut itself off from the rest of the facility to keep containment intact and prevent spread.

That makes the term Unit the best fit. A unit refers to a discrete, modular portion of a site or area that can operate as its own containment block and seal off when needed. In contrast, a Site is the whole facility, a Sector is a subdivision of a Site used for organization or management, and Armed is unrelated to facility structure.
