I Failed the CKA Exam, but My Second Attempt Changed Everything — Here’s How
Failing the Certified Kubernetes Administrator (CKA) exam on my first try was a tough experience, but it taught me valuable lessons. Here’s what I learned and tips to help you succeed:
1. Don’t Use a Laptop Screen for the Exam
The Linux Foundation changed the exam format in 2024. Now, you must connect to a remote desktop, and only one monitor is allowed during the exam. Using just a laptop screen makes it difficult to navigate and search for text due to the limited display size.
Recommendation:
- Use a secondary monitor for better visibility and efficiency.
- Set up an external webcam.
2. Understand the Open-Book Format
Linux Foundation exams are open-book, but the rules have changed:
- Before: You could use one browser tab and load the exam simulator on your local system, making it easy to access bookmarks of Kubernetes documentation.
- Now: You’ll be connected to a remote VM during the exam, so bookmarks are no longer an option. You’ll need to search the documentation manually.
Tip: Practice searching through the Kubernetes docs so you’re comfortable finding information quickly during the exam.
3. Master Imperative Commands
A strong grasp of imperative commands is essential for the exam. These commands will help you solve several questions effectively.
Here are two best resources from Kubernete Docs. Search “kubectl cheat sheet” & “kubectl reference” to get these two links during the exam.
These links can help you answer at least 4–5 questions within 5–10 minutes.
4. Save Money on Exam Fees
The CKA exam costs around $375, but you can save a lot during sales.
Tip:
- Look for discounts during Black Friday or Cyber Monday. Certification coupons can offer 60–80% off.
5. Prepare Your Exam Setup
A clear and organized setup is crucial for a smooth exam experience.
- Have a transparent water bottle.
- Ensure your external webcam and microphone are working perfectly.
- Keep your desk clean, as the proctor will ask you to show your surroundings.
This will help you avoid unnecessary distractions or embarrassment before starting the exam.
6. Manage Your Time Wisely
Time management can make or break your exam.
What I Did Wrong:
- I spent too much time on difficult networking questions, letting my ego get in the way.
- I ran out of time and couldn’t answer some easier questions.
What to Do Instead:
- Start with the easier questions to secure quick points.
- Leave troubleshooting and networking tasks for the end if they’re too time-consuming.
7. Study Resources
Here are some excellent resources to help you prepare:
- Killer Shell: Great for simulating real exam scenarios.
- KodeKloud: Complete all exercises twice for thorough practice.
- Kubernetes Documentation: The ultimate resource for module-wise learning. You can use this bookmark list for structured study.
Conclusion
Passing the CKA exam requires both theoretical knowledge and practical skills. By focusing on essential kubectl commands, studying resources like Kubernetes documentation, and practicing time management, you can overcome the challenges of the exam.
Good luck on your journey to becoming a Certified Kubernetes Administrator (CKA)!
