This Is What the CNPA Exam Looks Like

In one sentence

CNPA is a multiple-choice exam, and you pass by scoring 75% or more within 120 minutes.

Why read this first

The most common failure in certification study comes not from not knowing the content but from going in without knowing the shape of the exam. If you do not know what the passing score is, how tight the time is, or which domains have many questions, you cannot set your preparation priorities.

Official specification

Item	Value
Format	Multiple choice
Time limit	120 minutes
Passing score	75%
Number of questions	85
Exam fee	$250 (includes one retake)
Validity period	2 years

These values come from the candidate documentation on docs.linuxfoundation.org. The certification introduction page does not state the passing score or the number of questions, so if you prepare by looking only at that page, you will walk into the exam room without knowing the passing score.

Domain weights

Domain	Weight	Number of questions in this practice exam
Platform Engineering Core Fundamentals	36%	31 questions
Platform Observability, Security, and Conformance	20%	17 questions
Continuous Delivery and Platform Engineering	16%	13 questions
Platform APIs and Provisioning Infrastructure	12%	10 questions
IDPs and Developer Experience	8%	7 questions
Measuring your Platform	8%	7 questions

More questions come from the domains with larger weights. Use these proportions as the basis when you allocate study time. This practice exam also distributes its questions in the same proportions.

Where answers diverge

When you grade a practice exam, the questions you get wrong cluster in one shape. You get them wrong not because you do not know the content but because you miss which of two similar concepts is being asked about. When you read a question and one of the pairs below comes to mind, first separate them by the criterion in the third column.

This	That	What separates them
Platform	Collection of tools	If there is an interface that users use themselves, it is a platform
Golden path	Enforced standard	If you can leave it, it is a golden path
DORA's change failure rate	Recovery time	The share that was rolled back is the change failure rate
Internal developer portal	CI/CD	The place where you find things and request them is the portal
Self-service	Delegation	If it finishes without a request, it is self-service

This does not mean you should memorize the table. If you mark which pair each missed question fell on, the place you need to study again becomes much narrower than a domain name.

What you may consult while solving

In a multiple-choice exam, you cannot consult any materials. No documentation, no searching, and no notes are allowed. This is the biggest difference from a hands-on exam.

What you actually go through at the exam site

Many people lose time flustered by the procedure even though they know all the content.

The exam is taken with online proctoring on PSI's Bridge platform. The procedure in which the proctor verifies things by video takes up to 30 minutes, and during this time the questions do not open and the time limit does not start. Even so, you should leave your schedule open for 30 minutes of check-in plus the exam time.

There are four things checked at check-in. Agreeing to the non-disclosure agreement, a government-issued ID that exactly matches the name you registered, showing the room with your webcam, and closing unapproved software. Because of the last item, turning off background programs such as Slack or cloud sync in advance saves time.

There are a few conditions that are easy to trip over when taking it in Korea. Your ID must have a signature, so a passport is safest. You can use only one monitor, and dual monitors are not supported. There must be nothing both on top of and under the desk, writing on paper is prohibited, and reading the questions aloud is not allowed either. On a company network or VPN, AWS S3 access may be blocked and you may get caught at the pre-check.

You can change a reservation only up to 24 hours before the start. And if you book and do not show up, you not only lose the exam fee but also your retake eligibility disappears. The result arrives by email within 24 hours after the exam ends.

The exam fee includes one retake, and you must complete both the exam and the retake within 12 months of the original purchase date. There is no official waiting period, so you can retake right after receiving the result. Rather than postponing because you are not perfectly prepared, it is often better to sit it once and find out which domain is weak.

The certification is valid for 2 years. On top of this, the CARE program introduced in 2026 overlaps. If you pass CKA or CKAD, KCNA is renewed automatically, and if you pass CKS, KCSA and CKA are renewed automatically. However, you must earn the lower-level certification first for this chain to work. If you earn CKA first and KCNA later, that CKA does not renew KCNA. If you are aiming for Golden Kubestronaut, this order determines the renewal burden for the next several years.

How to use this practice exam

The time limit is set the same as the real exam. The remaining time is shown at the top of the screen, and when time runs out it is submitted automatically, and unanswered questions are treated as wrong. That is because the real exam also grades only what you solved by that point.

It is important to sit and finish it in one go. If you solve it while looking things up midway, the score goes up, but that score does not predict the real exam. What you want to check is not whether you know it but whether you clear the passing score within the time limit.

After reading the explanations of the questions you got wrong, go back and study the domain those questions belong to.
