Linux performance labs only
The learner correctly identified that the original Lesson 36 was not CKS-like: it required PowerShell parsing and extensive written analysis. Current Linux Foundation instructions describe CKS as 15–20 performance tasks solved from a Linux command line on designated hosts.
Permanent teaching rule
All graded CKS questions must be Linux command-line labs. Ask for concrete system changes and concise verification output, not essays, explanatory tables, multiple-choice responses, or PowerShell work. Named tools must be executed directly. If the current computer lacks the required environment, record an environment block and use a Linux Kubernetes lab rather than substituting literature work.
Difficulty rule
Make labs harder through interacting controls, realistic broken states, strict scope preservation, and tighter time limits. Do not make them harder through extra prose requirements.
kube-bench environment finding
The learner's production cluster runs Kubernetes v1.36.0. kube-bench v0.16.0 maps Kubernetes versions only through v1.34, where it selects cis-1.12. Do not use forced older benchmarks as Hero evidence or modify the v1.36 production control plane for training. Lesson 36 requires a disposable v1.34 kubeadm lab.
