Hi Steven,we have a 2 day instructor-led class to prep for that exam, the class is called ECS ExtremeWireless Cloud.
You can also watch the free self-paced videos, although these have not been updated and so have moved into the legacy / out of date folder under ‘Courses’ on our ExtremeDojo.
We also have a welcome series that is introductory level technical training whch introduces learners to our product families. The first Welcome Series Course is available now (more topics to follow): Meet ExtremeCloud.These global live-streamed classes are also available free of charge and are open to everyone. Upon completing the course, participants can take a certification exam and earn an Extreme Networks Associate Certification. Here is a link to that Youtube series.
Hope that helps!
