Throughout this journey, I received incredible support from this community and from many individuals who helped me personally. To give back, I’d like to share my entire preparation path — including the steps I followed, resources I used, challenges I faced, and key tips that helped me succeed.

Overview

• This exam isn’t easy if you’re not familiar with Kubernetes.

• The 2-hour hands-on exam is time-constrained and intense.

• With dedication, consistent practice, and the right strategy, you can pass confidently.

Resources I Used

1. [Piyush Sachdeva’s CKA Playlist (YouTube)] – Free and beginner-friendly.

2. KodeKloud CKA Course by Mumshad Mannambeth – Excellent for deep understanding.

3. KodeKloud Ultimate CKA Mock Exams – Covers every exam concept for practice.

4. Killer.sh – Two practice sessions (36 hours each) included with your exam voucher.

5. KillerKoda Scenarios – Free, perfect for troubleshooting-type questions.

Best Way to Prepare

• Don’t just watch videos — practice every concept hands-on.

• Set up a local cluster and practice to understand how Kubernetes works under the hood.

• Avoid overusing ChatGPT or AI tools for solving errors — debugging teaches you more.

• Practice daily to become comfortable with kubectl commands.

• Use imperative commands instead of YAML definitions when possible.

  • Example: kubectl = k, pods = po

  • Refer to Kubernetes Docs Quick Reference for shortcuts & all the kubectl commands.

• Learn Linux fundamentals — networking, file permissions, services, and processes.

• Memorize file paths for Kubernetes components and logs.

• Revisit difficult questions multiple times.

• Keep handwritten notes for quick last-minute revision.

• Use both Killer.sh sessions — they simulate the exam environment.

• Attempt all labs and mock exams on KodeKloud until fully confident.

Exam Experience – My Mistakes & Tips

Before the Exam

• Prepare your room for proctor verification.

• Use a wired Ethernet connection for stability; keep a mobile hotspot as backup.

• Start your exam 20 minutes early in case of technical issues.

During the Exam

• Two proctors are involved: one for environment & document verification and one for live monitoring.

  Everything went smoothly for me.

• I faced a firewall issue while opening kubernetes.io/docs manually. Use the preloaded Linux Foundation documentation link instead.

• Organized my setup with two terminals one in left other one in right and documentation side-by-side.

• The proctor warned me twice: once for reading questions , and once because my face wasn’t fully visible for some seconds only.

• Solving questions in easy-to-hard instead of numerical order that was a mistake for me — I spent 40 minutes on only 4 questions.

• Node Resource allocation questions can take time because i spent almost 20 minutes on this question after updating the cpu and memory resources in deployment the pods are not running .

  Tip: Wait a minute after updating deployments; pods may take time to initialize.

• Exam environment is laggy , especially pasting YAML & the screen resolutions is not ideal.

• Always verify object names and YAML files using kubectl describe. Double-check namespace.

• Exit nodes after solving questions, node names look very similar (e.g., cka00543, cka00653).

• Use Ctrl + F in the documentation for quick searches (e.g., kind: Pod).

• Use kubectl explain frequently — a lifesaver.

Mistakes i done!

• Forgot to delete old Ingress while migrating to Gateway API due to time pressure.

• Node resource allocation questions can take time. I spent almost 20 minutes on one question; after updating CPU and memory in the deployment, the pods didn’t run immediately.

  • Tip: Wait a minute after updating deployments; pods may take time to initialize..

• Avoid typing object names manually — small typos cost marks.

• Some questions test understanding of “namespaced” concept — read carefully.

• Created two storage classes on different nodes by mistake i forget to exit from node — always verify!

Pro Tip

• Solve easy questions first to build momentum.

• Allocate 6 minutes per question, and reserve last 20 minutes for review and corrections.

Final Result

After consistent effort and practice, I successfully cleared the **CKA exam .**This journey taught me not just Kubernetes, but also discipline, focus, and problem-solving under pressure.
