You are preparing to install an operating system on virtual machines (VMs) in a Hyper-V
environment. You need to configure each VM so that you can perform a network-based
operating system installation. What should you do for each VM?

A.
Add a Network Adapter.

B.
Add a Legacy Network Adapter.

C.
Configure a static MAC address.

D.
Configure a dynamic MAC address.

Explanation:
On the Installation Options page, choose the method you want to use to install the operating
system:
Install an operating system from a boot CD/DVD-ROM. You can use either physical media or
an image file (.iso file).
Install an operating system from a boot floppy disk.
Install an operating system from a network-based installation server. To use this option, you
must configure the virtual machine with a legacy network adapter connected to an external
virtual network. The external virtual network must have access to the same network as the
image server.
