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.
