How I passed Certified Kubernetes Administrator (CKA) Exam (quick tips)

Exam Score: 93. Passing score: 66.

4-6 weeks before Exam

Since CKA is an "open book" exam, you should be preparing with the mindset of knowing where to find stuff in the Kubernetes documentation.

If you are stuck while doing the practice questions after each chapter, dive into the official Kubernetes documentation to find your answer.
Don't rely on the course content to find your answers. Use it to understand concepts.
Begin bookmarking documentation pages you find helpful.
Run through the jsonpath practices.
After finishing the Killer.sh simulators, come back this course to run through as many practice questions as you can.

Comes with 2 free tries after you've registered for the CKA exam
Only use official Kubernetes documentation to find your answers
Take the opportunity to bookmark documentation pages you find helpful
Do not panic if you find yourself struggling, I did too. The simulator is very tough.
Practice setting up your Vimrc configuration, Kubectl autocomplete and alias.

Register for the CKA exam
Purchase a magnifying glass if you don't have one, in case you have issues with your webcam not being able to focus on your identification proof clearly. I faced this issue personally.
Ensure you have read through the Candidate Handbook and Important Instructions.
Buy a decent webcam if you do not have one.
Get a second monitor (or a monitor extension for your laptop). This is extremely helpful and reduces time required to alternate between windows.
Run the compatibility check tool and make sure everything is good.

Clear out your desk, including speakers. You don't need speakers for the exam.
Get a clear cup for water
Run the compatibility check tool again and make sure everything is good.
Go through the entire Kubernetes Cheat Sheet and get familiar with every line in it.

Always execute the switch context command displayed at every question before attempting the question, even if you think you are already on the correct context.
Do not get stuck on a question. Mark/Flag it and move on to the next.
Open a second browser window with a single tab on your second monitor, with all the bookmarks you need on the bookmark bar. Remember to let the proctor know that you have a second monitor.

These bookmarks have also been named according to what you see in the list.

Results usually come within 24 hours. For me, it was published almost exactly 24 hours later.

Good luck and all the best!
