CompTIA Network+ (N10-007) — Question 477

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

Answer options

Correct answer: D

Explanation

The correct answer is D, as a mantrap is specifically designed to prevent tailgating by controlling access through a two-door system that ensures only one person can enter at a time. The other options, while useful for access control, do not directly prevent unauthorized entry by allowing someone to follow another individual into a secure area.
