Which statement best describes the order of restricted areas from least to most secure?

• A. Level 1, Level 2, Level 3
• B. Level 2, Level 1, Level 3
• C. Level 3, Level 2, Level 1
• D. Level 1, Level 3, Level 2

Answer: (A)

Security levels are arranged so that protections intensify as you move up the scale. The area with the fewest controls is the least secure, and the area with the strongest controls is the most secure. So the sequence from least to most secure is Level 1, Level 2, Level 3. Level 1 typically has the basic access requirements, Level 2 adds stricter controls, and Level 3 enforces the highest level of authentication, authorization, and monitoring. Any ordering that places Level 3 before Level 2 or Level 1 would imply higher protections exist before lower ones, which doesn’t fit the intended progression.
