Too Long; Didn't Read
The best of bad advices about CKA do not give you a real competitive advantage and may even impediment your success. In retrospect, I can say some of these advices may not be worth your time. The understanding of the Kubernetes architecture required for the exam is quite basic, you should not be afraid. There is a task for everything in the official documentation. The exam is performance based. You have 3 hours to clear every (24) questions. If you do the maths, it means 7 minutes and 30 seconds by questions.
