220-1102 Question 373
Single answerFacial recognitionA company issues Windows 11 laptops with infrared (IR) cameras so users can sign in with facial recognition through Windows Hello. After a user receives prescription glasses with heavily tinted lenses, facial sign-in begins failing in normal office lighting, although the user can still sign in with a PIN. Other users on similar laptops are unaffected. As the technician, which action should you take FIRST to restore the user's facial recognition sign-in with the least disruption?
- A
Remove and re-create the user's facial recognition profile in Windows Hello, then have the user set up recognition again while wearing the new glasses
- B
Disable Windows Hello and require the user to sign in only with a password because facial recognition is no longer reliable
- C
Join the laptop to a different wireless network so the biometric template can resynchronize with the domain controller
- D
Replace the IR camera because any change in appearance indicates a hardware failure in the biometric sensor
Show answer and explanation
Correct answer: A
Explanation
This scenario tests practical troubleshooting of facial recognition in an enterprise Windows environment. For Windows Hello, the best initial response to a single-user recognition problem after an appearance change is to update the enrolled biometric data by improving recognition or re-enrolling the face profile. This follows standard troubleshooting best practices: verify scope, identify what changed, and choose the least invasive corrective action first. Microsoft documentation for Windows Hello supports using alternate sign-in methods such as PIN and reconfiguring facial recognition when recognition quality changes. Network changes and domain synchronization are not the primary factors for on-device facial recognition, and immediate hardware replacement is not justified when the symptoms point to a profile mismatch rather than sensor failure.
- A. Correct.
Correct. A significant appearance change such as new glasses can affect Windows Hello facial recognition performance. The least disruptive first step is to update or re-enroll the user's facial biometric profile so the system can learn the user's current appearance. In Windows, this is commonly handled by improving recognition or removing and setting up facial recognition again. Since the user can still access the device with a PIN, re-enrollment is practical and aligns with normal troubleshooting steps before replacing hardware.
- B. Incorrect.
Incorrect. Windows Hello is designed to work alongside fallback methods such as PIN sign-in, but disabling it is not the best first step. This option does not troubleshoot the likely cause and creates unnecessary user impact. The problem is limited to one user after an appearance change, which points to the stored biometric profile rather than a need to remove the feature entirely.
- C. Incorrect.
Incorrect. Facial recognition for local Windows Hello sign-in does not depend on changing wireless networks to synchronize a biometric template with a domain controller. This distractor reflects a common misconception that all authentication data is centrally synchronized in real time. In practice, Windows Hello sign-in on the device uses locally stored credentials and biometric factors tied to the device.
- D. Incorrect.
Incorrect. A hardware failure is less likely because other users on similar systems are unaffected and the issue began after the user's appearance changed. Replacing the camera before re-enrolling the user's face would be premature and more disruptive. Hardware replacement should come only after configuration and user-profile troubleshooting steps fail.
