What decides your score is not how many practice questions you read, but how many you get wrong and never review. The free AWS question set has 20 questions, while the real exam has 65, so the gap between reading and reviewing is where your marks come from. By the end of this guide you will know which aws cloud practitioner practice test options are free, what a full length mock really costs, and the exact format you must be ready for on exam day.
The AWS Certified Cloud Practitioner is the entry level exam in the AWS certification path, and it sits below the Associate level exams. Our AWS certification guide for 2026 maps the whole ladder if you want to see where this one leads.

How do I find a free aws cloud practitioner practice test?
Start with the free official material. The AWS Certification exam preparation page lists two free items on Skill Builder. The first is the Official Practice Question Set, which AWS describes as 20 question sets written by AWS that show the style of the real exams and include detailed feedback with recommended resources on every answer.
The second is the Exam Prep digital course. AWS describes those as 2 hour courses that walk through the topic areas and review sample certification questions for each domain. That is enough to cover the four domains once, and it costs nothing.
There is also a free pretest. The AWS Cloud Practitioner certification page tells you to take the AWS Certification Official Pretest to find the areas where your AWS knowledge needs a refresh. Do that first, because it points at the weak domains before you spend any money.
For a full length rehearsal, the same preparation page says you need a Skill Builder subscription to reach the Official Practice Exam, which scores you and explains every answer choice. Third party banks fill the middle. Whizlabs lists yearly subscriptions that run from $129 up to $259, while CloudCertPrep publishes free timed 65 question mocks built from the official exam guide. The free AWS material is the only source that matches the exact wording and distractor style of the live exam.
If you are still weighing AWS against another cloud track, read the best cloud certifications for career growth in 2026 before you spend anything.
What is the exact format of the AWS Cloud Practitioner exam?
The official AWS Certified Cloud Practitioner page lists a 90 minute exam with 65 questions in the Foundational category. The CLF-C02 exam guide fills in the rest. Fifty of the 65 questions are scored, and 15 are unscored items that AWS uses to check whether a question should appear on a future exam. You are not told which ones they are.
The guide also describes the only two question types you will see. A multiple choice question has one correct response and three incorrect responses, which AWS calls distractors. A multiple response question has two or more correct answers out of five or more options, and you select every answer that fits.
| Question type | Shape | How to answer |
|---|---|---|
| Multiple choice | One correct answer and three distractors | Pick the best single option and move on quickly |
| Multiple response | Two or more correct out of five or more options | Mark every option that is true, and only those |
Two details affect your score. Unanswered questions count as incorrect, but there is no penalty for guessing, so never leave a blank. And the exam uses a compensatory model, so a weak domain does not sink you on its own. You only have to clear the overall bar.
How much does the exam cost and what happens if you fail?
The AWS Certified Cloud Practitioner page lists the cost as 100 USD. You can sit the exam at a Pearson VUE testing center or as an online proctored session, and AWS offers it in 13 languages. Our AWS certification cost 2026 exam fee breakdown covers the fee level of every exam in the AWS catalog if you plan to go further.
Budget for the retake too. The AWS Certification FAQs say you must wait 14 calendar days after a failure before you become eligible again, that there is no limit on the number of attempts, and that you pay the full registration fee each time. One perk is worth knowing. The AWS Cloud Practitioner page says that once you hold any AWS certification you get 50 percent off your next exam.
What are the four exam domains and how much do they count?
The official CLF-C02 exam guide sets the weightings below. The two biggest domains are not the ones most beginners expect, which is exactly why the practice questions matter.
| Content domain | Weight | What the guide asks you to know |
|---|---|---|
| Cloud Concepts | 24 percent | The global infrastructure, cloud design principles, cost optimization, migration, and the Well-Architected Framework |
| Security and Compliance | 30 percent | The shared responsibility model, governance and compliance, access management, and security components |
| Cloud Technology and Services | 34 percent | Deployment methods, compute, database, network, storage, and artificial intelligence services |
| Billing, Pricing, and Support | 12 percent | AWS pricing models, billing and cost management tools, and AWS Support options |
Read that as a study plan. If the practice set shows you losing marks in Billing, Pricing, and Support, that is the smallest domain, but it is also the easiest to fix with a few hours of pricing and budget material.
How should I review my mistakes after a practice test?
Use the feedback. The AWS Official Practice Question Set explains every answer, and the full length Official Practice Exam tells you which domain you lost marks in. Keep an error log with four columns: the question, your answer, the right answer, and one line on why the distractors were tempting.
That last column is the one that matters. The CLF-C02 exam guide says the incorrect options are plausible on purpose and match the content area, so a question you got right for the wrong reason is still a wrong answer waiting to happen.
Redo only the questions you missed after three days. If you still miss one, look up the exact service page in the AWS documentation. Do not re-read all 20 questions again. Reviewing errors is what moves the score.
How many practice tests do you need before exam day?
Two full length timed mocks plus the free 20 question set is a workable plan. The first mock tells you your pace, and the second tells you whether the first one improved anything.
Work out your pace before you start. Sixty-five questions in 90 minutes gives you a little over 80 seconds per question. On the free set, mark every question where you hesitated, and that tells you which domains to slow down in on the day.
When you sit the real thing, leave the section level score report alone unless you failed. The CLF-C02 exam guide tells you to use caution when you read that feedback, because the scoring is compensatory and only the overall result counts. Our guide to passing AWS Certified Solutions Architect SAA-C03 carries the same advice for the next exam up.
One final check before you book. Make sure you meet the rules for your testing location, and read what the AWS certification prerequisites are in 2026 so you know what the path expects at each level.
