ExtremeCloud SD-WAN case studies
ExtremeCloud SD-WAN · Put your knowledge to work in context.
The ExtremeCloud SD-WAN credential is presented by Extreme Networks as a specialist-level certification focused on the company's SD-WAN solution, which the vendor lists alongside Network Security, Wireless Access and Wired Access in its Solutions catalogue. Extreme positions SD-WAN within a broader cloud-based networking story: the homepage describes "Unified management with AI for wired, wireless, SD-WAN, and security" as part of its cloud-based networking offering, so candidates should expect the exam to sit in that context rather than in isolation. The exam is aimed at network engineers, implementation consultants and operations staff who design, deploy and run SD-WAN overlays across branch sites. Four domains are covered, each weighted equally at 25 percent: fundamentals and solution architecture; deployment and provisioning; routing, policies and traffic steering; and operations, monitoring and troubleshooting. The ExtremeCloud SD-WAN case studies are 5 cases and about 3,122 words.
