[All MD-100 Questions]

You have a Microsoft Azure Active Directory (Azure AD) tenant.
Some users sign in to their computer by using Windows Hello for Business.
A user named User1 purchases a new computer and joins the computer to Azure AD.
User1 is not able to use Windows Hello for Business on his computer. User1 sign-in options are shown on the exhibit. (Click the Exhibit tab.)

You open Device Manager and confirm that all the hardware works correctly.
You need to ensure that User1 can use Windows Hello for Business facial recognition to sign in to the computer.
What should you do first?

  • A. Purchase an infrared (IR) camera.
  • B. Upgrade the computer to Windows 10 Enterprise.
  • C. Enable UEFI Secure Boot.
  • D. Install a virtual TPM driver.
Show Suggested Answer Hide Answer
Suggested Answer: A 🗳️
Windows Hello facial recognition requires an infrared (IR) camera. If your device does not have an infrared camera (or any other biometric device such as a fingerprint scanner), you will see the message shown in the exhibit. The question states that Device Manager shows all hardware is working properly. Therefore, it is not the case that the computer has an IR camera but it isn't working properly. The problem must be that the computer does not have an IR camera.
Incorrect Answers:
B: Windows 10 Enterprise is not required for Windows Hello. Windows Hello also works on Windows 10 Pro.
C: UEFI Secure Boot is not required for Windows Hello.
D: A virtual TPM driver is not required for Windows Hello.

I'm a little confused on this one as well. "All hardware works correctly" implies the IR camera as well, but Windows 10 enterprise is NOT required for Hello for Business. https://docs.microsoft.com/en-us/windows/security/identity-protection/hello-for-business/hello-overview

if all the hardware works correctly, does that not imply that there is a camera with IR there?

The user could have a camera without IR functionality. It would look fine in device manager, but is not compatible with Windows Hello.

And you consider that the laptop has no FingerPrint reader ... :-/ Meanwhile I have searched, Secure Boot, TPM and Win10 Enterprise are not pre-requisites... too.
