You work as the enterprise administrator at ABC.com. ABC.com has a domain named ABC.com. The ABC.com network servers run Microsoft Windows Server 2008 and the client computers run Microsoft Windows Vista. ABC.com has a computer named ABC-SR01 configured to host Windows Server virtualization service and hosts a virtual machine using the physical network interface card (NIC).

ABC.com has a Marketing division which uses the virtual machines to access physical network resources.

How would you configure the virtual host, when unable to access physical network resources using the virtual machine?

A.
By installing the Windows Server virtualization Guest Integration Components on the virtual machine.

B.
By installing the Virtual Machine Additions feature installed on ABC-SR01.

C.
By installing the MS loopback adapter installed on the virtual machine and ABC-SR01.

D.
By installing the Virtual Machine Additions feature installed on the virtual machine.

Explanation:
To ensure that the virtual host can connect to the physical network, you need to install Windows Server virtualization Guest Integration Components on the virtual machine.

The network adapter in the VM ported from Virtual Server to Windows Server is no longer recognized. The workaround is to add a legacy network adapter to the VM. The network adapter seen by the guest OS is not an emulated device (DEC/Intel 21140 Ethernet adapter). It is an entirely new, high performance, purely synthetic device available as part of the Windows Server virtualization Integration Components call Microsoft VMBus Network Adapter
