Looking for CKA practice test harder than killer.sh

charliej

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.
