You have a server that runs Windows Server 2008 R2. The server has the Hyper-V server role
installed. You create a new virtual machine and perform an installation of Windows Server 2003 on
the virtual machine. You configure the virtual machine to use the physical network card of the host
server. You notice that you are unable to access network resources from the virtual machine. You
need to ensure that the virtual host can connect to the physical network. What should you do?
A.
On the host server, install the Microsoft Loopback adapter.
B.
On the host server, enable the Multipath I/O feature.
C.
On the virtual machine, install the Microsoft Loopback adapter.
D.
On the virtual machine, install Microsoft Hyper-V Integration Components.
Explanation:
Networking and virtual machines To connect a virtual machine to a virtual network, you add a virtual
network adapter to the virtual machine and then connect the virtual network adapter to an existing
virtual network. There are two types of network adapters available for Hyper-V: a network adapter
and a legacy network adapter. The network adapter is designed specifically for Hyper-V and requires
a virtual machine driver that is included with the Hyper-V integration services. This type of
networking adapter provides better performance than a legacy network adapter and is the
recommended choice when it can be used. Because this type of virtual network adapter requires
integration services in the guest operating system, it can be used only with guest operating systems
for which integration services are available. Note If a network adapter is configured for a virtual
machine but integration services are not installed in the guest operating system, Device Manager
lists the network adapter as an unknown device. Source: http://technet.microsoft.com/enus/library/cc816585.aspx Integration services Integration services are available for supported guest
operating systems as described in the following table. Windows 2003 SP2 Guest operating system –
