CompTIA Security+ (SY0-601) — Question 314

Which of the following security controls can be used to prevent multiple people from using a unique card swipe and being admitted to a secure entrance?

Answer options

• A. Visitor logs
• B. Faraday cages
• C. Access control vestibules
• D. Motion detection sensors

Correct answer: C

Explanation

Access control vestibules are designed to limit entry to one person at a time, ensuring that a unique card swipe cannot be used by multiple individuals simultaneously. Visitor logs, Faraday cages, and motion detection sensors do not specifically prevent unauthorized shared access at entry points, making them less effective for this scenario.
