Which of the following statements about nested virtualization is true?

• A. Both the Hyper-V host and the guest VM must be Windows Server 2019 or later.
• B. Only the host must be Windows Server 2019 or later.
• C. The guest VM must be a Windows 10 edition.
• D. The feature is not supported on Windows Server 2016 or later.

Answer: (C)

Nested virtualization lets you run a Hyper-V hypervisor inside a virtual machine, so the inner VM can host its own VMs. For this to work on a Windows Server host, the inside VM must be a Windows 10 edition, since Windows 10 Pro/Enterprise/Education provide the Hyper-V features and virtualization extensions needed by the nested hypervisor. Windows Server editions inside the nested VM aren’t the supported configuration in this scenario. The host can be Windows Server 2016 or newer, and it doesn’t have to be 2019 or later.
