In the SD-WAN service model, the organization that sells the SD-WAN service to the subscriber may be different from which provider?

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

Answer: (A)

In SD-WAN service models, the party that sells the SD-WAN service to the subscriber can be a separate entity from the provider delivering the underlying network or platform. The selling organization might be a managed service provider, reseller, or VAR that bundles and provisions the SD-WAN solution for the customer, while the actual infrastructure and orchestration platform (the UCS provider) handles the underlay connectivity and SD-WAN control plane. This separation is common because the customer lands SD-WAN as a managed service from one party, even though the network and core service come from another.

End users or data centers are typically the customers, not the selling entities, and a separate service provider would usually be the network operator or the underlay provider rather than the reseller.
