Which pairing correctly matches a term with its description?

• A. Cantata — The MRP for infrastructure
• B. SD-WAN UNI Identifier — Identification used for management purposes
• C. Legato — Reference point for customer-provider relationships
• D. SD-WAN UNI L2 Interface — Identification used for management

Answer: (B)

In MEF SD-WAN terminology, the SD-WAN UNI is the interface that connects the customer network to the provider network, and the identifier assigned to that UNI is used specifically for management tasks. This identification helps provisioning, monitoring, fault isolation, and policy application across the SD-WAN service. The other pairings don’t align with standard MEF terms: Cantata isn’t a recognized term for infrastructure management; Legato isn’t a defined reference point for customer-provider relationships in this context; and an SD-WAN UNI L2 Interface describes the physical/virtual interface itself, not an identifier used for management. Therefore, the SD-WAN UNI Identifier as identification used for management purposes is the correct match.
