A. The scenario here is you have a cluster of Hyper-V servers that have multiple network cards connected to different subnets. Each Hyper-V server has multiple virtual switches configured. You have these virtual switches configured on each node in the cluster.
Remember that Hyper-V clusters require the virtual switches on all nodes in the cluster to have identical names. Hyper-V doesn't have to do any clever logic to ascertain which virtual switch it should connect the virtual NIC from a virtual machine to. Hyper-V just connects the virtual NIC to the virtual switch that has the same name as the virtual switch it was connected to on the previous node.Related Reading:
