QuestionQ15

Manage virtual machines

HOTSPOT -

You have a Hyper-V host named HV1 that contains a virtual machine named VM1.

VM1 has Dynamic Memory enabled. HV1 contains a PCIe NVMe storage device named Device1 that supports Discrete Device Assignment (DDA) and is disabled on HV1.

You need to ensure that Device1 can be assigned directly to VM1 by using DDA. The solution must perform only the configurations required for the assignment.

What should you do? To answer, select the appropriate options in the answer area.

NOTE: Each correct selection is worth one point.

Explanation

Discrete Device Assignment requires the owning virtual machine to run with a static memory allocation, because Dynamic Memory is not supported for a VM that has a directly assigned PCIe device, so Dynamic Memory must be disabled on VM1 before the device can be attached. The dismount and assignment operations for a DDA device (Dismount-VMHostAssignableDevice and Add-VMAssignableDevice) require the target virtual machine to be shut down, not merely saved or paused, so VM1 must be shut down as part of the preparation. On the host side, a device intended for DDA must first be disabled in the host operating system and then dismounted from the host partition with Dismount-VMHostAssignableDevice so Windows Server relinquishes control of it; because Device1 is already disabled, the only remaining host action needed is to dismount it, after which it can be mounted directly to VM1.
