I've taken the KCNA exam three times now, and each time I've scored exactly 71/75. I feel confident in Kubernetes since I've gone through various courses like KodeKloud multiple times, and I've practiced with exams on Udemy and all the hands-on labs on KodeKloud. Yet, I'm constantly running into questions that aren't covered by these resources, particularly on networking, security, and third-party tools like ArgoCD. It's frustrating because I feel unprepared for these unexpected questions. Any suggestions? I have one more chance to retake it!

I studied with a book by Nigel Poulton, which helped me pass. It might not address all the offbeat questions, but I found it highly useful overall.
How much hands-on work have you done with clusters? Setting up your own sandbox environments could help a lot. It seems like you're heavily focused on courses and exam content, but practical experience is also critical.
Isn’t it common to see similar questions when you retake exams? That's what I heard, but it sounds like you’re experiencing something different.
I've noticed that isn't the case for me either.
Doesn’t the Linux Foundation offer a course for KCNA? Have you tried that in addition to your other resources?
I have. I feel like it might be a personal issue since I keep getting the same score three times.

I’ve used k3d and minikube along with the KodeKloud sandboxes and exercises.
