You work as an administrator at Contoso.com. The Contoso.com network consists of a single domain named
Contoso.com. All servers in the Contoso.com domain, including domain controllers, have Windows Server
2012 R2 installed.
Contoso.com has a Hyper-V server, named ENSUREPASS-SR13, which hosts multiple virtual machines.
You have enabled the use of Single-root I/O virtualization.
Which of the following is TRUE with regards to using Single-root I/O virtualization? (Choose all that apply.)
A.
It maximizes network throughput, while minimizing network latency.
B.
It maximizes network throughput, as well as network latency.
C.
It avoids the virtual switch stack and allows the virtual machine direct access to the actual network switch.
D.
It prevents the virtual machine from accessing the network switch directly.
Explanation:
SR-IOV enables network traffic to bypass the software switch layer of the Hyper-V virtualizationstack. Because
the VF is assigned to a child partition, the network traffic flows directly between the VF and child partition. As a
result, the I/O overhead in the software emulation layer is diminished and achieves network performance that is
nearly the same performance as in nonvirtualized environments.
