What is the primary purpose of the SD-WAN UNI Identifier?

• A. Identification for management purposes
• B. Endpoint security enforcement
• C. Policy mapping device
• D. Network topology view

Answer: (A)

The SD-WAN UNI Identifier is used to uniquely identify the customer edge interface within the provider’s SD-WAN for management and provisioning. This identifier lets the service orchestrator reference the correct customer, site, and service during activation, policy assignment, monitoring, and troubleshooting, acting as a stable handle for management systems. It isn’t primarily about enforcing endpoint security, mapping policies, or viewing network topology—those functions are handled by security services, policy engines, and monitoring tools, respectively.
