220-1102 Question 500
Single answerFacial recognitionA company has issued Windows 11 laptops with infrared (IR) cameras so employees can sign in using facial recognition through Windows Hello. One employee reports that facial sign-in worked when the laptop was first deployed, but it now frequently fails in a dim conference room and after the employee started wearing new glasses. The employee can still sign in with a PIN. As the technician, which action should you take FIRST to restore the most reliable facial sign-in experience?
- A
Remove the user's PIN requirement so Windows is forced to rely only on facial recognition
- B
Re-enroll the user's facial recognition profile in Windows Hello, using the Improve recognition option while the user is wearing the glasses they normally use
- C
Disable the infrared camera in Device Manager and use the standard webcam for facial sign-in instead
- D
Reset the user's Microsoft account password and synchronize it with the local Windows profile
- E
Turn off multifactor sign-in policies so the user can authenticate with face data only
Show answer and explanation
Correct answer: B
Explanation
This scenario tests practical support knowledge for Windows Hello facial recognition. When facial sign-in becomes less reliable after a user changes appearance, such as adding glasses, the best first step is to update or improve the stored biometric profile. Microsoft documents that Windows Hello supports improving recognition data, including with changes like glasses, while retaining secure fallback methods such as a PIN. The dim room detail is a plausible distraction; Windows Hello facial recognition uses IR-capable hardware, which is generally more resilient than a normal webcam in low-light conditions. Therefore, the appearance change is the stronger indicator. Best practice is to confirm the camera is functioning, then re-enroll or improve recognition before escalating to driver or hardware troubleshooting.
- A. Incorrect.
Incorrect. Windows Hello is designed to use a PIN as a fallback authentication method, and removing it would reduce usability and potentially interfere with supported sign-in recovery options. Facial recognition should not be the only available sign-in method.
- B. Correct.
Correct. In Windows Hello, facial recognition can be improved by re-enrolling or using the Improve recognition feature, especially after changes such as wearing glasses or other appearance differences. This is the most appropriate first troubleshooting step when the hardware still functions and the user can authenticate with a PIN.
- C. Incorrect.
Incorrect. Windows Hello facial recognition requires compatible biometric hardware, typically an IR camera, not a standard RGB webcam. Disabling the IR camera would prevent supported facial recognition rather than improve it.
- D. Incorrect.
Incorrect. A password reset does not address biometric matching issues related to appearance changes or environmental conditions. Since the user can still sign in with a PIN, the problem is not an account password synchronization issue.
- E. Incorrect.
Incorrect. Disabling multifactor or related sign-in policies is not an appropriate fix for a biometric recognition issue and would weaken security. Facial recognition in business environments is typically part of a broader authentication strategy, not a reason to reduce controls.
