Which two actions should you perform?

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
single-root 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.
