Explanation

In an NFV environment following Cisco NFV Infrastructure and ETSI MANO architecture, the onboarding workflow for VNF deployment follows this high-level order: Define VNF descriptors (VNFD and NSD) - Includes implementation details and service definitions. Prepare virtual machine resources - Flavor, image, CPU/memory/storage, and placement. Define the NFV network - This step builds the underlay/overlay connectivity needed for the VNF. ?It includes virtual network creation, interfaces, VLs (Virtual Links), connection points, and mapping into OpenStack (Neutron networks, subnets, ports). - No VNF can be deployed until the NFV service networks (management, control, data, HA) are Apply Day-0 configuration - Bootstrapping/initial config. Apply Day-1 operational characteristics - Routing, services, policies. Configure operational monitoring (KPIs) - Performance and fault measurements. Since the question states "after the VM resources are prepared", the next mandatory stage is defining the virtual network connectivity on which the VNFs will operate.
