Which Kubernetes certification should you take first?

New to cloud native

KCNA gives broad conceptual coverage before you commit to a role-specific performance exam.

Already administering Kubernetes

CKA directly tests cluster administration and troubleshooting in a command-line environment.

Building applications

CKAD is the role-specific route for designing, building and deploying applications on Kubernetes.

Security path

KCSA can provide conceptual security foundations. CKS is the hands-on specialist credential and requires CKA first, so a practical security route is often KCSA → CKA → CKS when foundational security knowledge is still developing.
