CompTIA Security+ (SY0-701) — Question 147

Which of the following is the best way to secure an on-site data center against intrusion from an insider?

Answer options

• A. Bollards
• B. Access badge
• C. Motion sensor
• D. Video surveillance

Correct answer: B

Explanation

An access badge ensures that only authorized personnel can enter the data center, thereby minimizing the risk of insider threats. While bollards can protect the facility from vehicle attacks, motion sensors and video surveillance are more about monitoring and responding to breaches rather than preventing them through controlled access.
