Which term describes the default point of application for the three logical constraint locations in SD-WAN attributes?

• A. SD-WAN Virtual Connection End Point
• B. SD-WAN UNI
• C. PVC
• D. TVC

Answer: (A)

In SD-WAN, the rules and constraints—such as security, QoS, and path selection—are applied at the boundary that defines a virtual connection. That boundary is the SD-WAN Virtual Connection End Point, which acts as the anchor where the virtual connection is instantiated and where those attributes are enforced across all possible transport paths. This ensures consistent behavior no matter which path the traffic uses inside the SD-WAN fabric.

The other terms describe different parts of networking and don’t serve as the default enforcement point for SD-WAN attribute constraints: the SD-WAN UNI is the customer-side interface to the provider network, and PVC/TV C are traditional circuit concepts not used as the SD-WAN attribute enforcement boundary.
