Which UCS type is described as an underlay path that is not shared and may be tenant-specific?

• A. Private UCS
• B. Public UCS
• C. Flat Rate UCS
• D. Non Shared Underlay Transport

Answer: (D)

In MEF SD-WAN, UCS types describe how the underlying transport (the underlay) is provisioned and shared. The phrase “not shared and may be tenant-specific” points to a path that is dedicated to a single tenant rather than used by multiple tenants at once. That is exactly what a Non Shared Underlay Transport provides: a dedicated, isolated underlay path for one tenant, which can be configured to meet that tenant’s specific needs.

Public UCS describes a shared underlay used by many tenants, so it wouldn’t be tenant-specific. Flat Rate UCS concerns pricing, not whether the path is shared or dedicated. Private UCS implies a private underlay as well, but the emphasis on non-sharing and potential tenant-specific tailoring fits the explicit definition of Non Shared Underlay Transport.
