A. You can, but it isn't an ideal situation. Normally, the cluster network isn't routed and is dedicated to only Cluster Shared Volumes (CSV) and cluster traffic.

Virtual LANs are one option to separate your traffic into virtual networks across the single physical NIC, depending on your environment.
