After you analyze your network environment, you decide to implement a full separation model for Internet access and MPLS L3VPN services. For which reason do you make this decision?

The full separation model is a specific architectural choice that enforces separation, not one that provides flexibility to choose whether to separate or centralize individual services.

Mixing services generally increases complexity and management overhead, especially when security and performance isolation are critical, making separation a more manageable approach for complex scenarios.

A full separation model often requires more edge routers or logically separate routing instances (e.g., VRFs) to achieve the necessary isolation, not just one edge router.

By fully separating Internet access from MPLS L3VPN services, the External Gateway Protocols (e.g., BGP) and Interior Gateway Protocols (e.g., OSPF/IS-IS) can operate in isolation, providing better security, stability, and control over routing policies without interference.
