CompTIA Network+ (N10-007) — Question 275

A security administrator wants to implement the ability to prevent an unauthorized user from tailgating into the office building. Which of the following should be implemented?

Answer options

• A. Badge reader
• B. Bluetooth reader
• C. Cipher lock
• D. Mantrap

Correct answer: D

Explanation

The correct answer is D, as a mantrap is specifically designed to prevent unauthorized access by requiring users to authenticate before entering the secure area. Options A, B, and C do not provide the same level of protection against tailgating, as they do not control access in a way that prevents multiple individuals from entering at once.
