What is MEF 3.0's relevance to SD-WAN?

• A. MEF 3.0 defines a vendor-locked SD-WAN framework.
• B. MEF 3.0 establishes only the data-plane encapsulation standards.
• C. MEF 3.0 is not related to SD-WAN.
• D. MEF 3.0 provides a standardized framework for service orchestration, lifecycle management, and open interfaces, enabling consistent multi-domain SD-WAN services.

Answer: (D)

MEF 3.0 provides a standardized framework for how services are described, provisioned, and managed across multiple domains and vendors. In SD-WAN, you need to dynamically assemble and manage a service that spans many sites and transport networks, often across different providers. MEF 3.0 supports this through a structured approach to service orchestration and lifecycle management, plus open interfaces and common information models that enable interoperability. This means operators can describe an SD-WAN service once, automate its provisioning and lifecycle operations, and apply consistent policies across diverse networks. The result is multi-domain SD-WAN services that are interoperable, scalable, and easier to automate, rather than being tied to a single vendor’s solutions.
