Which entity represents the organization that uses the subscribed SD-WAN services and specifies service attributes?

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

Answer: (B)

In SD-WAN, the organization that subscribes to the service and specifies what the service should do is the subscriber. This entity defines the requirements and attributes you’d expect to tailor the network, such as which sites to connect, required bandwidth, QoS policies, security controls, failover behavior, and SLAs. The service provider delivers and manages the underlying transport and orchestration, but the subscriber is the customer using and shaping the SD-WAN service. The UNI (the customer edge interface) is simply the connection point between customer equipment and the provider’s network, not the entity that defines the service attributes. PVC is a legacy term for a virtual circuit and isn’t about who uses or configures the SD-WAN service.
