The correct answer is A. Path isolation D. Services virtualization. Using VLANs and VRFs to virtualize both the data and control planes for end-to-end path separation maps to the path isolation and services virtualization models in Cisco's network virtualization framework.
Question
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 It must maintain end-to-end logical path transport separation across the network resources available grouped at the access edge. Which two primary models can this network virtualization design be categorized? (Choose two)
Options
- APath isolation
- BSession isolation
- CGroup virtualization
- DServices virtualization
- EEdge isolation

Why each option
Using VLANs and VRFs to virtualize both the data and control planes for end-to-end path separation maps to the path isolation and services virtualization models in Cisco's network virtualization framework.
Path isolation uses VLANs at the data plane and VRFs at the control plane to create separate logical forwarding paths through shared physical infrastructure, directly matching the requirement for end-to-end logical path transport separation.
Session isolation is not a recognized primary category within Cisco's campus network virtualization design framework.
Group virtualization refers to policy-based grouping of endpoints and does not specifically address end-to-end path separation using VLANs and VRFs.
Services virtualization groups and abstracts network resources - including those available at the access edge - into virtualized service instances, complementing path isolation to fulfill the complete end-to-end virtualization solution described.
Edge isolation is not a defined primary network virtualization model in Cisco's framework and does not describe the end-to-end separation required.
