help Certified Kubernetes Security Specialist (CKS) FAQ
Do I need the CKA before I can take the Certified Kubernetes Security Specialist exam?
Yes. The Linux Foundation and CNCF require you to hold a current Certified Kubernetes Administrator (CKA) credential before you can sit for the CKS, so it cannot be your first Kubernetes certification.
Is the CKS exam multiple choice or hands-on?
It is entirely performance-based: a two-hour, online-proctored lab where you work in live Kubernetes clusters. There are no multiple-choice questions, and tasks cover areas like cluster hardening, admission controllers, network policies, and image security.
Which tools does the CKS curriculum actually test you on?
The official curriculum explicitly names tools such as Falco for runtime threat detection, kube-bench for CIS Benchmark auditing, Trivy for image scanning, and OPA Gatekeeper for policy enforcement. You are expected to run these in the exam environment, not just know them conceptually.
