Just passed the CKA with 93% on my first attempt !!!
One question I couldn’t fully complete was on external etcd migration. I managed to troubleshoot the API server, scheduler, and controller manager, and got the control plane accessible. Most pods were up, but CoreDNS had an admission error (one CoreDNS pod was still running, and cluster resources were accessible). I started troubleshooting further but ran out of time.
Curious if anyone else completed that scenario successfully?
Preparation:
I used KodeKloud and completed the 3 main mock exams + the additional 5 mock exams course. If you go through all 8, you’ll be well-prepared—most real exam scenarios are covered (except a bit around Helm, Jobs, and StatefulSets).
Tips:
- Get comfortable navigating the Kubernetes docs quickly—it’s a huge advantage during the exam.
- Don’t stress if Killer Shell feels too hard—it’s meant to improve your speed and time management.
- Practice under time constraints—that’s key.
Final note:
If you’re preparing, don’t panic. The exam is very doable with the right practice.
Thanks to this amazing community—reading your posts and insights really helped me push through when things felt tough.
All the best to everyone preparing for the exam!
