You work for a company named ABC.com. Your role of Network Administrator includes the management of the
company’s physical and virtual infrastructure. The network includes servers running Windows Server 2008 R2
Service Pack 1 (SP1) and Windows Server 2012.
Virtual machines (VMs) are hosted on Windows Server 2012 servers running the Hyper-V role. One Windows
Server 2012 Hyper-V host server is named ABC-HVHost10. ABC-HVHost10 has four quad-core processors,
48GB RAM and six physical network adapters configured as three network adapter teams. ABC-HVHost10 also
has two Host Bus Adapters (HBAs) and connects to a Fiber Channel SAN.
You plan to configure a VM named ABC-Data1. Large amounts of data will be transferred to and from ABCData1 over the network.
You need to maximize the network performance of ABC-Data1 by assigning a physical network adapter directly
to the VM.
What should you do?
A.
You should configure Virtual Machine Chimney.
B.
You should configure NUMA topology.
C.
You should configure Single-root I/O virtualization.
D.
You should configure Multipath I/O.
E.
You should configure Resource metering.
F.
You should configure Virtual Fiber Channel.
Correct.
R2. In Hyper-V, SR-IOV enables network traffic to bypass the software switch layer of the Hyper-V virtualization stack and reduce I/O overhead. If you assign
only SR-IOV–enabled virtual network adapters and switches to a VM, the network performance of the VM can be nearly as good as that of a physical machine. In addition, the processing overhead on the host is reduced.
