Most people meet cloud native certification through the Kubernetes credentials — CKA, CKAD and CKS — and assume everything else is a step on the same ladder. It is not. Alongside them, CNCF and The Linux Foundation run seven associate-level exams, and each one certifies a different project or concern: the cloud native landscape as a whole, its security model, its metrics stack, its tracing standard, its service mesh, its delivery model, and the Argo project. Passing one says nothing about the others.
They are also remarkably uniform in shape, which makes the choice a question of subject rather than of difficulty. Every one of the seven has no prerequisites, costs $250 for the exam alone, is valid for two years, carries a 12-month eligibility window and includes one retake. Six of the seven are 90-minute multiple-choice exams rated at beginner level. Only ICA breaks the pattern — two hours, performance-based as well as multiple choice, and rated intermediate — which makes it the one that genuinely needs cluster time rather than recall.
That uniformity is the useful part: since none of them gates another and all of them cost the same, there is no ordering to obey and no reason to take one you do not care about. The right question is which project you already touch, or want to touch next. Below, each exam is broken down with what it tests and who it suits, followed by a decision guide. Every figure here was read off the Linux Foundation certification pages in August 2026 — confirm the current price and policy at the source before you buy, because bundles and terms change. Gnoseed neither sells, proctors nor guarantees any of these exams; it is a free study companion.
