Which entity represents the organization that provides the services and service attributes for a SD-WAN subscriber?

• A. SD-WAN Subscriber
• B. UNI
• C. VNF
• D. SD-WAN Service Provider

Answer: (D)

In SD-WAN, who defines and delivers the services and their attributes to the customer is the service provider. This organization creates the service offerings, sets the attributes like bandwidth, QoS policies, security rules, and SLAs, and manages provisioning for the subscriber. The subscriber is the customer who uses the service, not the one who defines or provides it. The UNI is simply the interface point between customer and provider, not the provider itself. A VNF is a software function used within the network to deliver specific capabilities, but it’s a component, not the organization that delivers services to the subscriber. Therefore, the entity that provides the services and service attributes for an SD-WAN subscriber is the SD-WAN Service Provider.
