Actual exam question from Microsoft's 70-740

Question #: 232
Topic #: 1

You have a server named Server1 that runs Windows Server 2016. Server1 has two network adapters that support single root I/O virtualization (SR-IOV). The network adapters are from two different vendors.
You plan to install the Hyper-V server role on Server1, and then to create a virtual machine named VM1 that runs Windows Server 2016. VM1 will use SR-IOV.
You need to ensure that VM1 can use both network adapters for load balancing and failover.
What should you do?

A. On Server1, create two virtual switches without embedded teaming. On VM1, create one NIC team.
B. On Server1, create one virtual switch without embedded teaming. On VM1, create one NIC team.
C. On Server1, create one NIC team. On VM1, create one NIC team.
D. On Server1, create one virtual switch that has embedded teaming. On VM1, create two NIC teams.

A is correct in my opinion. 2 NICs max for a Team within a VM. This is asking for that answer.

"NIC Teaming in Windows Server 2016 supports teams with two members in VMs. You can create larger teams, but there is no support for larger teams. Every team member must connect to a different external Hyper-V Virtual Switch, and the VM's networking interfaces must be configured to allow teaming."

Also, Switch Embedded Teaming requires both NICs to have the same manufacturer, same model, same firmware and driver.

So you can eliminate answer D directly.

i think is B. On Server1, create one virtual switch without embedded teaming. On VM1, create one NIC team.

how can you nic team one switch? surely >1 is required for a team?

You don't need two switches for teaming, you need two NICs (surely it's NIC teaming, not switch teaming)! So I also think it is B, since NICs are from different vendors, you cannot create an embedded switch

I was wrong, since both NICs use SRV-IO from different vendors, the only sollution is to create 2 virtual switches, and assign them to the VM. Then, in the VM you can use them to create a team -> answer = A and thus correct
