正解:A
SD-WAN is a software-based approach to managing and optimizing the performance of wide area networks (WANs). It allows organizations to connect users to applications through the most appropriate path, whether it's a private WAN, a public internet connection, or a combination of both. With SD-WAN, the network traffic is automatically routed over the best available link based on policies set by the organization, this allows fully support applications hosted in on-premises data centers, public or private clouds, and SaaS services.
