CompTIA A+ Core 2 (220-1102) — Question 612

Which of the following could be used to implement secure physical access to a data center?

Answer options

• A. Geofence
• B. Alarm system
• C. Badge reader
• D. Motion sensor

Correct answer: C

Explanation

A badge reader is specifically designed to control access by requiring authorized personnel to present a valid badge for entry, making it the most effective option for secure physical access. While geofences and alarm systems provide security measures, they do not directly control entry to the facility. Motion sensors are useful for detecting movement but do not prevent unauthorized access on their own.
