Which statement best orders the restricted areas from highest security to lowest security?

• A. Exclusion Area, Limited Area, Controlled Area
• B. Exclusion Area, Controlled Area, Limited Area
• C. Limited Area, Exclusion Area, Controlled Area
• D. Controlled Area, Exclusion Area, Limited Area

Answer: (A)

Access is arranged in layers with the strictest controls on the most sensitive zones. Exclusion Areas are the tightest, where entry is denied to anyone not explicitly authorized for that space, often requiring special clearance, formal authorization, and sometimes escorting. Within or adjacent to that level are Limited Areas, which are still restricted but allow access only to personnel with specific authorization and for defined tasks, with tighter controls on who can be there and when. The broadest of the three is the Controlled Area, where access is more permissive than the others but still governed by security measures such as badges and access checks. So the order from highest security to lowest is Exclusion Area, Limited Area, Controlled Area.
