Question

You have a Microsoft 365 subscription that has Windows 365 Enterprise licenses. You plan to use a custom Windows 11 image as a template for Cloud PCs. You have a Hyper-V virtual machine that runs Windows 11 and has the following configurations:

  • Name: VM1
  • Disk size: 64 GB
  • Disk format: VHDX
  • Disk type: Fixed size
  • Generation: Generation 2

You need to ensure that you can use VM1 as a source for the custom image. What should you do on VM1 first?

Options

  • AChange the disk type to Dynamically expanding.
  • BChange the disk format to the VHD.
  • CChange the generation to Generation 1.
  • DIncrease the disk size.

Why each option

To use a Hyper-V VM as a custom image source for Windows 365 Cloud PCs, the virtual hard disk must be dynamically expanding. VM1's fixed-size disk needs to be converted to meet this requirement.

AChange the disk type to Dynamically expanding.Correct

Windows 365 custom images require the virtual hard disk to be of the dynamically expanding type, not fixed size. Changing the disk type to dynamically expanding ensures compatibility for provisioning Cloud PCs more efficiently.

BChange the disk format to the VHD.

VHDX is the recommended and supported disk format for Windows 365 custom images, so changing it to VHD would be incorrect.

CChange the generation to Generation 1.

Windows 365 custom images require Generation 2 virtual machines, which VM1 already is, so changing it to Generation 1 is unnecessary and incorrect.

DIncrease the disk size.

The current disk size of 64 GB meets the minimum requirement for a Windows 11 Cloud PC image, so increasing it is not a prerequisite for usability.
