MEF Software-Defined Wide Area Network (SD-WAN) Practice Exam

The key idea is that traffic destined for the public Internet exits the SD-WAN path at the edge rather than being sent through the SD-WAN core or back to a central data center. When an application flow is designed to go to the Internet directly, this is called Internet Breakout. It lets internet-bound traffic leave the edge locally, reducing backhaul and latency for web, SaaS, and other Internet destinations. Local Internet Breakout is the same concept but emphasizes the location of the exit (at the branch), which isn’t specified in the scenario. Cloud Breakout refers to direct access to cloud services specifically, and Global Internet Exit isn’t a standard term in SD-WAN.
