The task
Task
- Create a list of all cert-manager CRDs and save it to

What this tests
Build clusters with kubeadm, manage RBAC, etcd, and the control plane, and install a CNI. On the CKA exam, Cluster Architecture, Installation & Configuration tasks are graded purely on what you build in the cluster — not multiple choice — so the only way to get faster is to do them on a real cluster against a clock.
Practice it for real
prepium.sh drops you into your own isolated Kubernetes cluster in the browser — no install, no credit card. You solve the task in a real terminal, hit validate, and a programmatic checker scores exactly what you got right and wrong (with partial credit). The canonical solution unlocks after you attempt it, so you learn the fast, exam-ready way to do it.
