Which abbreviation is used for the Private Virtual Cloud in SD-WAN terms?

• A. VNF
• B. PVC
• C. PNF
• D. UNI

Answer: (B)

In SD-WAN context, the term Private Virtual Cloud refers to the isolated, enterprise-controlled cloud-like network fabric used to securely link sites. The standard abbreviation for this is PVC. This fits because PVC literally stands for Private Virtual Cloud, signaling a private, virtualized cloud environment within the SD-WAN architecture.

The other terms indicate different things: VNF is Virtual Network Function (software-based network functions), PNF is Physical Network Function (hardware-based), and UNI is User-Network Interface (the access point where a customer edge connects to the network). These do not denote Private Virtual Cloud, which is why PVC is the correct choice.
