Which organization sells the SD-WAN service to the subscriber?

• A. UCS provider
• B. End User
• C. Data Center
• D. Service Provider

Answer: (D)

SD-WAN is offered and sold by the service provider. In MEF SD-WAN models, the service provider bundles connectivity, SD-WAN edge services, management, and orchestration into a service that is sold to the customer (the subscriber). The subscriber is the organization that consumes the service, not the seller. A data center is just a location for hosting resources, and a UCS provider is primarily a hardware vendor, not the entity selling the SD-WAN service to customers in this context.
