CompTIA Network+ (N10-007) — Question 644

A network team has reported multiple outages caused by unauthorized access to the IDF. Which of the following would BEST prevent this issue from reoccurring?

Answer options

• A. Video surveillance
• B. Badge readers
• C. Motion sensors
• D. Tamper switches

Correct answer: B

Explanation

Implementing badge readers ensures that only authorized personnel can access the IDF, significantly reducing the risk of unauthorized access. While video surveillance, motion sensors, and tamper switches can enhance security, they do not directly control access to the facility like badge readers do.
