# 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.
