A company has Hyper-v host servers that run WindowsServer 2012. The company also has virtual machines
that run Windows Server 2008 R2 or Windows Server 2012.
You upgrade the Hyper-V host servers to Windows Server 2012 R2.
You need to ensure that all virtual machines can PXE boot by using a standard network adapter.
What should you do?
A.
Create Generation 2 virtual machines.
B.
Upgrade all existing virtual machines to Windows Server 2012 R2.
C.
Upgrade the existing virtual machines that run Windows Server 2008 R2 to Windows Server 2012 R2.
D.
Create Generation 1 virtual machines.
Isn’t C correct? One must first use an OS that allows for Gen 2 VMs and that is 2012 R2 and Win 8.1.

I agree with you, first it’s necessary the right SO… then you have prerequisites to Generation 2 VM. But if Microsoft have another idea??? this is the real problem =(
I believe that A is the best option for Microsoft, because you can upgrade Win2008 to 2012 without convert VM to Generation 2, and only Gen2 is possible for PXE boot.

They upgraded the hyper-v hosts to 2012 R2, so that requirement has been met.

A: is correct. The os doesn’t matter, you’re PXE booting. Without a gen 2 vm you wont pxe boot.

Generation 2 Virtual Machine Overview
http://technet.microsoft.com/en-us/library/dn282285.aspx
Generation 2 Provides the following new functionality on a virtual machine:
– PXE boot by using a standard network adapter
– Boot from a SCSI virtual hard disk
– Boot from a SCSI virtual DVD
– Secure Boot (enabled by default)
– UEFI firmware support
The following guest operating systems are supported as generation 2 virtual machines:
– Windows Server 2012 R2
– Windows Server 2012
– 64-bit versions of Windows 8.1
– 64-bit versions of Windows 8

From the available answers, A should be correct. BUT, as it states here: http://technet.microsoft.com/en-us/library/dn282285.aspx
PXE boot by using a standard network adapter
In previous versions of Hyper-V, if you wanted to perform a remote installation of the guest operating system by using PXE boot, you were required to install a legacy network adapter. Legacy network adapters are not available in generation 2 virtual machines. Generation 2 virtual machines support PXE boot by using a standard network adapter.
and this is a tutorial that illustrates the procedure: http://www.danielclasson.com/guide-how-to-get-pxe-boot-to-work-in-hyper-v/
So, a Generation 2 VM is not a prerequisite to boot a VM from PXE. It’s just what the limited available options gives us as a satisfactory answer…

u r so wrong. The tutorial you link uses a “legacy” adapter. You need a gen2 vm for pxe with a standard adapter.

The correct answer is A, you need legacy adapter for PXE boot, I had this problem not a while ago when I was testing OS Deployment from SCCM and my VMs were not booting, after creating Gen 2 VM and added legacy adapter it worked like a charm.

I seriously doubt you did that.
You state: “after creating Gen 2 VM and added legacy adapter”. However Gen 2 does not support Legacy adapters. You don’t get the option to add a Legacy Adapter.
So keep you BS to yourself

This question doesn’t make much sense
A: partially correct but it doesn’t meet the requirement for ALL VMs supporting PXE boot from standard NIC
C: in order to use Gen2 we need 2012/8, but even if we upgrade 2008 to 2012, we can’t change Gen1 to Gen2

I think that’s why A is right. You can upgrade the OS but still couldn’t convert to Gen 2. Answer A is assuming you’ll install Win 8/8.1 or Server 2012/R2 after you create a Gen 2 VM.
