You have a server named Host1 that runs Windows Server 2012 and has the Hyper-V
server role installed.
Host1 has one physical network adapter. You plan to deploy 15 virtual machines on Host1.
You need to implement a networking solution that ensures that all of the virtual machines use PXE to boot when they connect to
Windows Deployment Server (WDS).
What should you do?
A.
Install legacy network adapters for each virtual machine
B.
Modify the settings of the virtual switch.
C.
Modify the settings of the network adapter for each virtual machine.
D.
Install a second physical network adapter
Explanation:
Since Windows Server 2012 R2 (WS2012 R2) Hyper-V and Windows 8.1 Client Hyper-V, there are two generations of
virtual machine hardware specification.
Generation 1 virtual machines (the only generation on legacy versions of Hyper-V) make things a little tricky when it comes to PXE
booting. The default (and better performing) synthetic Network Adapter (that leverages the Hyper-V integration components) does not
support booting off of the network in Generation 1 virtual machines. If you do want to boot this type of virtual hardware using PXE then
you must add an emulated Legacy Network Adapter.

Hyper-V provides two types of virtual network adapters—a network adapter and a legacy network adapter:
– A network adapter requires a virtual machine driver in order to work, but offers better performance. This driver is included with some newer versions of Windows. On all other supported operating systems, install integration services in the guest operating system to install the virtual machine driver. For instructions, see Install a Guest Operating System. For more information about which operating systems are supported and which of those require you to install integration services, see About Virtual Machines and Guest Operating Systems (http://go.microsoft.com/fwlink/?LinkID=128037).
– A legacy network adapter works without installing a virtual machine driver. The legacy network adapter emulates a physical network adapter, multiport DEC 21140 10/100TX 100 MB. A legacy network adapter also supports network-based installations because it includes the ability to boot to the Pre-Execution Environment (PXE boot). However, the legacy network adapter is not supported in the 64-bit edition of Windows Server 2003.
