1. Provides various materials such as seminar videos for practice and theory 2. I was able to understand the big picture architecture concept, and following the hands-on helped me organize the concept of Kubernetes, which was difficult for beginners. 3. I sincerely appreciate the instructor's passion for teaching me even the smallest details in an easy and detailed way. I only had one of the textbooks you showed me, but I didn't look at it, but from today, I will look at that textbook and learn more one by one and challenge myself for the CKA. Thank you.
