Explanation/Reference: https://technet.microsoft.com/en-us/itpro/powershell/windows/netadapter/set-netadapterrss "Set-NetAdapterRss -Enabled $True" is equivalent to "Enable-NetAdapterRss". RSS is a scalability technology that distributes the receive network traffic among multiple processors by hashing the header of the incoming packet. Without RSS, network traffic is received on the first processor which can quickly reach full utilization limiting receive network throughput.

I think A.Set-NetAdapterRss is correct. Since the question says "by mulitple network processors". Also only A.Set-NetAdapterRss can be used on VM.

Correct answer "A.Set-NetAdapterRSS" is VM-based cmdlet. Since "B.Set-NetAdapterRdma", "C.Set-NetAdapterQos" and "D. Set-NetAdapterSriov" are host-based cmdlet, you can exclude them. Namely all of them can be exclude by computer type, such as host and VM.
