AZ-802 Manage Virtual Machines Practice Question

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  Enable-WindowsOptionalFeature -FeatureName Microsoft-Hyper-V

  Why it's wrong here

  This command is used to install the Hyper-V role on a Windows operating system. While it is necessary to run this inside the guest VM eventually, it will fail unless the physical host has first been configured to pass through the virtualization extensions to that specific virtual machine's hardware profile.

• ✗

  Set-VMNetworkAdapter -MacAddressSpoofing On

  Why it's wrong here

  MAC address spoofing is often required in nested virtualization to allow the inner VMs to communicate over the network through the outer VM's adapter. However, this command does not enable the CPU's virtualization extensions, which is the primary hardware requirement for installing the Hyper-V role in a guest.

• ✗

  Set-VMMemory -DynamicMemoryEnabled $false

  Why it's wrong here

  Nested virtualization in earlier versions of Hyper-V required static memory, but modern versions on Windows Server 2022 are more flexible. Regardless, disabling dynamic memory is not the action that enables the virtualization extensions needed to run a hypervisor within the guest; that requires a specific processor-level configuration.

• ✗

  Set-VMProcessor -ExposeVirtualizationExtensions $true

  Why it's wrong here

  This command is the essential step for enabling nested virtualization. By setting the -ExposeVirtualizationExtensions parameter to true for a specific VM, the Hyper-V host passes the hardware-assisted virtualization features (like Intel VT-x or AMD-V) to the guest VM, allowing it to function as a hypervisor itself.
