CNPA (Certified Cloud Native Platform Engineering Associate): exam format, domains and the Golden path

What is the CNPA exam?

CNPA is the Certified Cloud Native Platform Engineering Associate exam from the Linux Foundation and CNCF. It is a proctored, online, multiple-choice exam on platform engineering: the discipline of building internal platforms that give development teams self-service access to infrastructure, delivery and tooling. It covers the core fundamentals of platform engineering, platform observability, security and conformance, continuous delivery, platform APIs and infrastructure provisioning, internal developer platforms and developer experience, and how to measure a platform. It is a knowledge exam, and its format is the documented exception to the other multiple-choice exams: more questions and a longer duration. Officially it is the Certified Cloud Native Platform Engineering Associate certification, a multiple-choice exam in the Golden tier of the 16-certification Golden Kubestronaut program. The sections below cover its official domains, the verified format and cost, and its place in the path.

Expect questions on concepts rather than commands: what makes a platform a product, how golden paths and self-service reduce cognitive load, how declarative APIs and controllers provision infrastructure, and which metrics show whether a platform is working for its users.

CNPA exam domains and weights

CNPA has six domains. Platform Engineering Core Fundamentals is the largest at 36%. Platform Observability, Security, and Conformance follows at 20%, Continuous Delivery & Platform Engineering at 16%, Platform APIs and Provisioning Infrastructure at 12%, and IDPs and Developer Experience and Measuring your Platform at 8% each. The fundamentals domain is therefore the priority: platform thinking, team topologies, golden paths and the platform-as-a-product mindset. Weights come from the official certification page, checked on 23 October 2026. The official list has 6 domains: the largest is Platform Engineering Core Fundamentals at 36% and the smallest is Measuring your Platform at 8%, so a sensible plan splits study time roughly in proportion to these weights.

The smaller domains are narrower but concrete, covering observability and policy for the platform itself, delivery pipelines, declarative provisioning APIs, developer portals and the measurement of platform success.

CNPA exam format and cost

The CNPA exam facts below were read from the official Linux Foundation pages on 2026-10-23, and every row of the table links to the page it came from. Format: Online, proctored, multiple-choice. Questions: 85. Duration: 120 minutes. Passing score: 75%. Price: 250 US dollars. Certification validity: 2 years. Prerequisites: None. Retake policy: One retake per exam purchase if a passing score is not achieved. Curriculum version: not published by the Linux Foundation. Prices and policies change, so confirm them on the official CNPA page before you book. If the Linux Foundation changes a value, this page is updated and shows the date it was last verified.

With 85 questions in 120 minutes you have about 85 seconds per question on average, which is enough to read a scenario carefully but not to agonise over one item. If every question counts equally, 75% of 85 is 64 correct answers, so one unknown topic does not decide the result. Flag a hard question, move on, and return to it at the end.

Treat the table as the single source for numbers on this page. If a row says the Linux Foundation does not publish a value, we print that instead of guessing, and the official CNPA page remains the final word on registration and policy.

How GoldenKube practice works for CNPA

The GoldenKube question bank for CNPA is not available yet; it is coming. This page therefore covers the exam itself, with its official domains, weights and facts, and shows where CNPA sits in the Golden Kubestronaut program, but it does not link to a practice session. For the other certifications in the program that do have a bank, GoldenKube works as a practice loop: one question at a time, instant feedback with an explanation, adaptive ordering toward weak domains, spaced repetition for missed questions, and a mock exam mode. The first 10 answers need no sign-up, and after that a free account saves progress with no credit card. Until CNPA is covered, prepare from the official curriculum and the project documentation.

• Read the official CNPA curriculum and exam page for the authoritative domain list.
• Use the weights above to decide how much time each domain deserves.
• Practice with the official documentation open, since the questions follow it.

Where CNPA sits in the Golden Kubestronaut path

CNPA is a Golden-tier certification, not one of the 5 core Kubestronaut certifications, and Golden Kubestronaut requires all 16 certifications in the program, so CNPA is a required step (required since 15 Oct 2025). Its own prerequisites, per the Linux Foundation: None. The program page lists all 16 certifications side by side and marks which ones GoldenKube can practice today. It is the conceptual counterpart to CNPE, the hands-on platform engineer exam, and it connects to the tools examined elsewhere in the path: GitOps in CGOA and CAPA, developer portals in CBA, policy in KCA and telemetry in OTCA. Taking CNPA gives you the vocabulary that ties those tool-level exams together.

The GoldenKube question bank for CNPA is not available yet; it is coming. The program page lists all sixteen certifications and shows which of them can be practiced today.
