SSCP Practice Question: Which THREE are appropriate controls to prevent…
Which THREE are appropriate controls to prevent unauthorized access to a data center? (Choose three.)
⚠ Common exam trap
ISC2 often tests the distinction between physical access controls (e.g., biometrics, mantrap, guards) and logical/technical controls (e.g., firewall, encryption), leading candidates to mistakenly select network or data protection mechanisms for a physical security question.

Correct answer & explanation
✓
Biometric scanner
A biometric scanner is a physical access control that authenticates individuals based on unique physiological characteristics (e.g., fingerprints, iris patterns). It directly prevents unauthorized entry by verifying identity at the data center perimeter, making it an appropriate control for physical security.
