Looking for CKA practice test harder than killer.sh

Hi everyone,

I’m preparing for the CKA exam and I’ve already gone through the killer.sh practice environment. I found it useful, but I’m wondering if there are any other practice tests or hands-on labs that closely match the real exam’s difficulty or are possibly even more challenging.

If you have recommendations for platforms, mock exams, lab environments, or self-study resources that push the difficulty level beyond killer.sh, I’d really appreciate your suggestions. Thanks in advance!

    If you’ve already done killer.sh, you might try the CertBoosters practice test. It's not similar in style, but questions are based on real world scenarios, so you end up doing more actual troubleshooting instead of just following patterns. I found them harder, which was good to learn core concepts.

    Outside of that, KodeKloud’s labs are still useful for repetition, but honestly the best “hard mode” is just spinning up your own cluster (kind/k3s/kubeadm) and breaking/fixing things. For example, try recovering etcd from backup or debugging a stuck control plane component. That kind of practice helped me more than any mock exam.

    During my preparation for the CKA, I had a similar experience. Although killer.sh is unquestionably one of the environments that is closest to the actual exam, I eventually realized that I needed more variety and slightly more difficult troubleshooting scenarios.
    A few things that helped me beyond killer.sh:
    1. KodeKloud hands-on labs and mock exams
    2. Mumshad’s CKA scenarios for speed practice
    3. Setting up your own cluster and intentionally breaking components to practice recovery
    4. With timed tasks, GitHub CKA challenges repositories.
    I also came across CertifyCerts practice questions during revision. What I liked was that some scenario-based questions forced me to think under pressure instead of just memorizing commands, which helped with exam confidence.
    In my opinion, combining timed practice + troubleshooting in a live cluster is what makes the biggest difference for the actual exam.
    Good luck with your preparation!
