CompTIA A+ Core 2 (220-1202) — Question 39

Which of the following prevents forced entry into a building?

Answer options

• A. PIV card
• B. Motion-activated lighting
• C. Video surveillance
• D. Bollard

Correct answer: D

Explanation

A bollard is a strong, short vertical post that can effectively block vehicles and deter forced entry. While a PIV card, motion-activated lighting, and video surveillance enhance security, they do not physically prevent someone from entering a building like a bollard does.
