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.

Answer: D, E

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.
