How to Prepare
- → Hold a current CKA first — CKS assumes that operational baseline
- → Practice hands-on with real security tooling (network policies, Pod security standards, admission controllers) in a lab cluster
- → Review the CNCF's current official curriculum, since this is one of the faster-evolving certification tracks
