An enterprise campus is adopting a network virtualization design solution with these requirements ?It must include the ability to virtualize the data plane and control plane by using VLANs and VRFs ?I

Path isolation describes the use of VLANs to separate the data plane and VRFs to separate the control plane, creating logically independent forwarding paths that maintain end-to-end transport separation across the entire campus - directly matching the stated requirements.

Session isolation is not a recognized primary model in Cisco campus network virtualization design and does not correspond to any of the described design requirements.

Group virtualization describes logical user or device groupings at the access layer and is a component that feeds into path isolation and services virtualization rather than a standalone primary design model category in this framework.

Services virtualization addresses the grouping and policy-based allocation of network resources at the access edge, enabling scalable per-group or per-tenant service assignment that maps to the requirement of grouping available resources at the access edge.

Edge isolation is not a defined primary model within the Cisco campus network virtualization architecture and does not map to the described design characteristics.
