I suppose the important point here is the need for RDMA that only SET can provide.

Yes. If RDMA was not mentioned, then I guess NIC Teaming could also be the correct answer.

It doesn't say there is a need for RDMA. It says the NICs have it enabled, but not that it is required in the solution.

Maybe you CAN do both but you SHOULD do D, since RDMA gives you extra performance.

I think the given answer D.Siwtch Embedded Teaming is correct. I believe B or D can be selected. However, since the question says RDMA-enabled and to use SDN, you should select D.

D is correct, as this is a new technology for 2016 over 2012. https://docs.microsoft.com/en-us/windows-server/virtualization/hyper-v-virtual-switch/rdma-and-switch-embedded-teaming
