How many zones are described within the security zone?

• A. Five
• B. Three
• C. Four
• D. Six

Answer: (A)

Interpreting how a security zone is divided into subzones and counting the distinct areas described is what this item tests. When a diagram or description lays out separate, bounded areas within the security zone, each labeled region counts as one zone.

In this case, the security zone is described as containing five distinct zones. Each zone is separately defined and bounded, so the total within the security zone is five. If you tried to count three or four, you’d be omitting one or more labeled regions that the description explicitly includes. There isn’t an indication of an extra zone beyond those five, so six would be beyond what’s described.
