Your network contains an Active Directory domain named contoso.com. The domain contains a
server named Server1 that runs Windows Server 2012 R2.Server1 has the Hyper-V server role
installed. Server1 has a virtual switch named RDS Virtual.
You replace all of the network adapters on Server1 with new network adapters that support singleroot I/O visualization (SR-IOV).
You need to enable SR-IOV for all of the virtual machines on Server1.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose
two.)

A.
On each virtual machine, modify the Advanced Features settings of the network adapter.

B.
Modify the settings of the RDS Virtual virtual switch.

C.
On each virtual machine, modify the BIOS settings.

D.
Delete, and then recreate the RDS Virtual virtual switch.

E.
On each virtual machine, modify the Hardware Acceleration settings of the network adapter.

Explanation:
The first step when allowing a virtual machine to have connectivity to a physical network is to create
an external virtual switch using Virtual Switch Manager in Hyper-V Manager. The additional step that
is necessary when using SR-IOV is to ensure the checkbox is checked when the virtual switch is being
created. It is not possible to change a “non SR-IOV mode” external virtual switch into an “SR-IOV
mode” switch. The choice must be made a switch creation time. Thus you should first delete the
existing virtual switch and then recreate it.
E: Once a virtual switch has been created, the next step is to configure a virtual machine. SR-IOV in
Windows Server “8” is supported on x64 editions of Windows “8” as a guest operating system (as in
Windows “8” Server, and Windows “8” client x64, but not x86 client).We have rearranged the
settings for a virtual machine to introduce sub-nodes under a network adapter, one of which is the
hardware acceleration node. At the bottom is a checkbox to enable SR-IOV.
