CompTIA Network+ (N10-007) — Question 607

Which of the following can be used to prevent unauthorized employees from entering restricted areas?

Answer options

• A. Sign-in sheets
• B. Video cameras
• C. Motion sensors
• D. Swipe badges

Correct answer: D

Explanation

Swipe badges are a direct means of controlling access to restricted areas by ensuring that only authorized personnel can enter. While sign-in sheets, video cameras, and motion sensors can assist in monitoring or recording who enters, they do not actively prevent unauthorized access like swipe badges do.
