A company has a new Hyper-V host server that runs Windows Server 2012 R2 Datacenter edition. You plan to deploy a new virtual machine (VM). You must install Windows Server 2012 R2 Standard edition on the VM from a standard network adapter by using PXE boot. The VM must boot to a SCSI VHDX disk.
You need to create the VM.
What should you create?
A. a storage pool that uses SCSI disks
B. a Generation 1 VM
C. a Generation 2 VM
D. a virtual disk that uses the VHDX format

A virtual machine created with Generation 1 supports legacy drivers and uses Hyper-V BIOS-based architecture. Hyper-V BIOS-based virtual machines can only initialize IDE Controller for Operating System to initialize a file system, which is shown in the below image:
On the other hand, a virtual machine created with Generation 2 supports UEFI-based architecture, in which a subset of Integration Service components has been included to allow SCSI Controller to initialize before the Operating System starts loading This is shown in the below image:
What you see in the above screenshot is that the Generation 2 Virtual Machine no longer loads the legacy drivers (IDE and Legacy Network Adaptors) A majority of the legacy drivers have been removed from a virtual machine that has been created using Generation 2, but a subset of Integration Services components has been included to initialize at boot and before control is returned to the Operating System. This includes initializing and loading SCSI Controller driver before the Operating System starts loading.
