CompTIA Security+ (SY0-501) — Question 502

An audit reported has identifies a weakness that could allow unauthorized personnel access to the facility at its main entrance and from there gain access to the network. Which of the following would BEST resolve the vulnerability?

Answer options

• A. Faraday cage
• B. Air gap
• C. Mantrap
• D. Bollards

Correct answer: C

Explanation

The correct answer is C, as a mantrap is a security measure designed to control access by requiring individuals to pass through two doors in succession, preventing unauthorized entry. The other options, like a Faraday cage (A), which blocks electromagnetic signals, and an air gap (B), which isolates networks, do not directly address physical access control, while bollards (D) provide physical barriers but do not manage entry authorization.
