The image is a diagram that shows a single system with one NIC. The NIC is configured with three VNICs. Each VNIC supports a single zone. The three VNICs are connected to one virtual switch. This switch provides the connection between the VNICs and the physical NIC upon which the VNICs are built. The physical interface connects to a switch and then to the Internet.
