Certified Information Systems Security Professional (CISSP) — Question 274

Which of the following is an important design feature for the outer door of a mantrap?

Answer options

• A. Allow it to be opened by an alarmed emergency button.
• B. Do not allow anyone to enter it alone.
• C. Do not allow it to be observed by closed-circuit television (CCTV) cameras.
• D. Allow it be opened when the inner door of the mantrap is also open.

Correct answer: A

Explanation

Allowing the outer door to be opened by an alarmed emergency button is critical for safety and quick exit in emergencies. The other options focus on restrictive measures that do not enhance the safety features of the door, such as preventing solo entry or visibility by cameras, which does not address immediate safety needs.
