Domain 2 30% Security and Compliance
Domain 3 34% Cloud Technology and Services
Domain 4 12% Billing, Pricing, and Support

Question Types Explained
Multiple-Choice (Single Select)

You are presented with a question and four answer options (A–D). One answer is correct, and the other three are distractors. These make up the majority of the exam.

Multiple-Response (Multi-Select)

You are given a question with five or more options and asked to select two or more correct answers. The question states exactly how many to pick (e.g., "Choose TWO"). There is no partial credit — you must select every correct answer and no incorrect answer to earn the point. If you are unsure of one required answer, eliminate the clearly wrong options first to improve your odds.

Scoring and Unscored Questions

The exam uses scaled scoring from 100 to 1,000, with 700 as the passing line. Of the 65 questions, 15 are unscored pretest items that AWS uses to evaluate future content. You cannot tell which questions are unscored, so treat every question as if it counts. AWS uses a compensatory scoring model : you do not need to pass each domain individually — a strong performance in one domain can offset a weaker performance in another, so long as your overall scaled score reaches 700.

Most AWS Certification exams do not display a pass/fail result when you finish. Your results appear in your AWS Certification account within five business days , and the score report can include a table of classifications showing your performance in each section. If you pass, the Credly digital badge email may arrive before the results are posted.

Prerequisites and Audience

AWS states there are no formal prerequisites : candidates could have up to 6 months of exposure to the AWS Cloud, but this is not required. The CLF-C02 is ideal for:

Cloud beginners starting the AWS certification path
Business professionals (sales, finance, project managers, procurement) who work with technical teams
IT professionals transitioning into cloud roles

Students and career-changers building foundational cloud knowledge before pursuing Associate-level certifications such as Solutions Architect Associate

How to Register and Exam Day

Register through your account at aws.training (or the AWS Certification portal), choose CLF-C02 , select Pearson VUE as the delivery provider, and pick a test center or online proctoring slot. The fee is $100 USD .

At a test center , bring two forms of valid ID (one government-issued photo ID); no personal items are allowed in the testing room. For online proctoring , you need a government-issued photo ID, a quiet private room with a clear desk, a working webcam, and a stable internet connection — no second monitors, phones, notes, or other people in the room. Check in 30 minutes early to complete identity verification.

Retake Policy and Recertification

If you do not pass, you must wait 14 calendar days before retaking the exam, and there is no limit on exam attempts — though you pay the full $100 fee each time. Once you pass, you cannot retake the same exam for two years. Use the section-level feedback in your score report to target your weaker domains before re-sitting, remembering that AWS describes this feedback as general information.

To recertify before your 3-year window closes, pass the latest version of the Cloud Practitioner exam or pass an Associate-level or Professional-level AWS exam, such as Solutions Architect – Associate, which also demonstrates progression beyond the foundational tier. Once you earn one AWS Certification, you get a 50% discount on other AWS Certification exams, which can offset the cost of moving on to an Associate certification.
