220-1102 Question 331
Single answerFacial recognition technology (FRT)A company deploys facial recognition technology (FRT) to let employees unlock company-issued laptops. Several users report that the system works reliably in bright office lighting but often fails in a dim warehouse. As the support technician, you need to recommend the BEST next step that improves authentication reliability without reducing security. What should you do?
- A
Disable facial recognition and require users to share a generic warehouse login for faster access
- B
Advise users to improve lighting conditions or reposition themselves so the camera can capture a clearer facial image during sign-in
- C
Lower the facial recognition match threshold so the system will accept less accurate scans in darker areas
- D
Replace facial recognition with a simple picture of each employee stored locally on the laptop for offline comparison
Show answer and explanation
Correct answer: B
Explanation
The best answer is to improve the conditions under which the facial recognition system captures the user's face. In real support scenarios, biometric authentication problems are often caused by environmental issues such as low light, camera angle, obstructions, or poor initial enrollment. The correct response is to troubleshoot those factors first rather than weaken authentication settings or replace individual credentials with insecure alternatives. This aligns with standard security best practices: preserve unique user authentication, avoid lowering security controls unnecessarily, and address the actual cause of failure. Vendor documentation for biometric sign-in platforms commonly recommends adequate lighting, proper user positioning, and re-enrollment if image quality is poor.
- A. Incorrect.
This is incorrect. Shared accounts reduce accountability and violate basic security best practices. In A+ Core 2 contexts, maintaining individual authentication and auditability is important. Using a generic login would make it impossible to track which employee accessed a device and would weaken security rather than solve the environmental issue affecting FRT.
- B. Correct.
This is correct. Facial recognition systems depend on the camera capturing usable facial details. Poor lighting is a common real-world factor that reduces accuracy. Improving ambient light or having the user face the camera more directly addresses the root cause while preserving the stronger convenience-and-security balance of biometric sign-in. This is the most appropriate troubleshooting step before considering major changes.
- C. Incorrect.
This is incorrect. Reducing the match threshold may increase false accepts, meaning an unauthorized person could be recognized as a valid user. That would directly reduce security. A common misconception is that biometric failures should be fixed by making matching less strict, but best practice is to improve image quality or enrollment conditions instead of weakening authentication standards.
- D. Incorrect.
This is incorrect. Storing a simple local picture is not equivalent to a secure biometric authentication process. Facial recognition systems use more than a static image file and are designed to compare biometric characteristics through approved authentication methods. Replacing FRT with a plain stored photo would be insecure and easily bypassed.
