What this tests

Wire up configmaps, secrets, service accounts, RBAC, securityContext, and resource limits. On the CKAD exam, Application Environment, Configuration and Security 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

The public description lets you study the task before signing up. Full access includes this live lab; the selected Task of the Week is free with an account. 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). You can open the solution while practising, then retry and use the failed checks to improve your score.
