Passing CKA Exam the Easy Way

If you want to pass the CKA exam in the easy way, here is what you have to do.

Note: I don’t recommend the easy way. However, choose this way only if you are in a hurry or need to have the CKA certification.

  1. Take the Udemy CKA course with the interactive practice test.
  2. Learn all the core concepts from the course
  3. Go through all the interactive practice test sections. If you are a beginner, go through the practice test multiple times.
  4. If you do the above three, it means you are ready to take the exam.

Register and appear for the CKA exam. You should be able to pass the CKA exam. For some reason, if you are not able to get the pass mark, don’t worry. You will have a free retake, and for the next attempt, you will know what to do as you went through the exam.

Passing CKA Exam the Hard Way

Here is what you need to do if you want to learn all kubernetes concepts in the right way and pass the CKA exam without any shortcuts.

  1. Learn all Kubernetes concepts from scratch. Here is what you can do to learn the kubernetes basics.
    • Read a kubernetes book.
    • Subscribe for a kubernetes course
    • Read the official documentation.
    • Create a list of all kubernetes concepts and read useful blogs on how it is implemented in real-time projects. You will find so many blogs.
  2. Go through Kubernetes the hard way task. It will teach you all the essential components that are part of a kubernetes cluster.
  3. Go through all the official kubernetes tasks which are part of the kubernetes documentation.
  4. [Optional] You go through the official Linux Foundation CKA training material.
