The hands-on experience of this test showcases a candidate's skills better than any other certification I have gone through. Instead of memorizing hundreds of settings or gotchas, it focuses on the ability to get to the implementation of a solution. I wish all certifications were done in this way.

It covered the fundamentals of Kubernetes well. I definitely feel more confident with Kubernetes, and I think that the active way of examining these skills is 100% the correct way to go about this exam. If the aforementioned comments are perceived to make the exam harder, I would happily accept and sign up for an Advanced Kubernetes Ecosystem exam immediately.

I liked the fact that all important commands to be entered before starting a question are highlighted appropriately. Additionally, there was a copy button for each highlighted word/command to easily copy into terminal, this makes the life of examinees very easy. Thank you!
