In SD-WAN, which description best matches having multiple UNIs for service access, each with its own UNI service attributes?

• A. Two OR MORE UNIs where the subscriber accesses service each with corresponding UNI service attributes
• B. EXACTLY ONE SWVC with SWVC attributes
• C. SD-WAN Edge function
• D. Inter frame gap

Answer: (A)

This question is about how UNI-based access is described in SD-WAN. UNI stands for User-Network Interface—the boundary where the customer connects to the provider’s network. When you have multiple UNIs, you’re connecting through more than one customer-side interface, and each of those interfaces can have its own set of service attributes (such as bandwidth limits, QoS profiles, SLA terms, or VLAN tagging). That exact setup—two or more UNIs with corresponding UNI service attributes—captures the scenario of having distinct access points, each with its own configured service characteristics.

Having a single SWVC implies one virtual circuit path with one set of attributes, which doesn’t match the idea of multiple UNIs with different attributes. The SD-WAN Edge function describes the device’s role rather than describing how many UNIs or their per-UNI attributes exist. Inter frame gap is a hardware timing parameter and not related to SD-WAN service access.

So the description that best matches the scenario is two or more UNIs where the subscriber accesses service each with corresponding UNI service attributes.
