Cloud Native Platform Engineering Associate (CNPA)

Platform engineering as a discipline: building an internal platform as a product, with golden paths, self-service APIs, conformance guardrails, and measurement that tells you whether any of it is working.

CNPA is not an operations exam. It assumes Kubernetes knowledge and tests the layer above: what to build, for whom, how to expose it, and how to know if it succeeded.

Exam Details

  • Exam Code: CNPA
  • Duration: 120 minutes (longer than other CNCF associate exams)
  • Questions: 60, multiple choice and multiple select
  • Passing Score: 75%
  • Cost: USD 250, includes one free retake
  • Validity: 2 years
  • Prerequisites: None formal; cloud native fundamentals assumed
  • Format: Knowledge-based, not hands-on

The idea the exam is built on

A platform is a product, and its users are engineers who can choose not to use it.

That single framing generates most of the correct answers:

  • If nobody adopts it voluntarily, it has failed, regardless of technical quality. Mandating adoption hides the failure rather than fixing it.
  • The value is reduced cognitive load, not more capability. A platform that adds concepts developers must learn has made things worse.
  • Golden paths are opinionated defaults that are the easiest route, not the only route. A platform that forbids alternatives is a gate, not a paved road.
  • Requirements come from user research and feedback, not from what the platform team finds interesting to build.
  • The thinnest viable platform is the goal: build the least that delivers value, and prefer a managed service over building your own.

Whenever an option describes mandating, gating, or building something a managed service already provides, it is usually the wrong answer.

Study sequence

  1. Read the CNCF Platforms White Paper. It is the syllabus, and it is short.
  2. Read the Platform Engineering Maturity Model. The attributes and levels are directly testable.
  3. Core fundamentals, which is 36% of the exam.
  4. Observability, multi-tenancy, and conformance.
  5. Delivery, platform APIs, and provisioning.
  6. Developer experience and measurement.
