General

Is CloudCertPrep really free?

Yes, 100% free with no hidden fees, premium tiers, paywalls, or ads. Every practice question, full-length mock exam, domain practice session, and progress tracker is completely free.

Do I need to create an account?

No account is required to practice. Guest mode gives you full access to every practice question and mock exam. Creating a free account unlocks progress tracking, exam history, domain mastery analytics, and the spaced repetition algorithm in domain practice.

Is CloudCertPrep open source?

Yes, CloudCertPrep is 100% open source under the MIT license. View the source, contribute new certifications or questions, report errors, or fork the project at https://github.com/nastaso/cloudcertprep. Community contributions are welcome; see CONTRIBUTING.md for the question schema and contribution workflow.

Does CloudCertPrep provide CLF-C02 exam dumps?

No. We do not provide exam dumps, which are leaked or stolen real exam questions that violate the AWS Certification agreement and can get your certification revoked. Every CloudCertPrep question is original, written from the published AWS exam guide and AWS documentation, and aligned to the current CLF-C02 domains. The goal is to teach the material so you pass legitimately, not to memorise stolen answers.

Exam format

What is the format of the AWS Cloud Practitioner practice exams?

Practice exams mirror the real AWS Cloud Practitioner (CLF-C02) exam: 65 multiple-choice and multiple-response questions in 90 minutes, scaled scoring from 100 to 1000 with a 700 passing threshold. With 1,050+ questions in the pool, you get over 10^100 possible exam combinations.

How accurate is this as an AWS Cloud Practitioner exam simulator?

Questions are written to match the difficulty, style, and topic distribution of the real CLF-C02 exam. The interface replicates the AWS testing experience: timed sessions, flagging, review screens, and scaled scoring. Questions are kept up to date with the 2026 exam guide and reviewed against AWS official documentation.

Is the AWS Cloud Practitioner exam hard?

CLF-C02 is the entry-level AWS certification and is designed for candidates new to AWS. The exam tests breadth (services, billing, security basics) rather than deep technical implementation. With consistent practice and review of explanations, most candidates pass on their first attempt.

What is a good score on AWS Cloud Practitioner?

The passing score is 700 out of 1000 (scaled). 700 to 800 is passing, 800 to 900 is strong, and 900+ is excellent. Aim for 800+ on practice exams here before scheduling the real exam. That gives you a comfortable margin for exam-day variance.

What is the AWS Cloud Practitioner pass rate?

AWS does not publish official pass rates for any certification, so any specific percentage you see online is an estimate, not an AWS figure. CLF-C02 is the entry-level exam and is widely regarded as the most approachable AWS certification: candidates who study the exam guide, practise consistently, and review explanations typically pass on their first attempt. Treat your scores on full-length practice exams here as the best available predictor: a steady 800+ signals you are ready.

How realistic are CloudCertPrep practice exams?

Very realistic. Our CLF-C02 mock exams mirror the real AWS Cloud Practitioner format: 65 questions in 90 minutes, scaled 100 to 1000 with a 700 pass mark. Questions match the difficulty, style, and domain weighting of the official exam guide, so practice scores closely track real exam-day performance.

Are the practice questions aligned to the current exam guide?

Yes. Every CLF-C02 question is written against the current AWS Cloud Practitioner exam guide (CLF-C02) and mapped to its domains and task statements. The open-source bank is reviewed via GitHub pull request and updated whenever AWS revises the guide, so coverage stays aligned with what the real exam tests.

Does every question have a detailed explanation?

Yes. Every CLF-C02 practice question ships with a full explanation covering why the correct answer is right and why each distractor is wrong. Explanations reference AWS concepts and documentation, so you learn the reasoning rather than memorising answers. The entire bank is publicly auditable on GitHub under the MIT license.

How much does the AWS Cloud Practitioner exam cost?

The AWS Certified Cloud Practitioner (CLF-C02) exam costs 100 USD (prices vary slightly by region and local tax). AWS occasionally offers a free retake or a 50% discount voucher to candidates who hold an existing AWS certification, so check your AWS Certification account for available benefits before booking. Practising here is free; only the official exam at Pearson VUE or PSI carries the fee.

Is there an AWS Cloud Practitioner exam voucher or discount?

AWS issues a 50% discount voucher to candidates who already hold an AWS certification, redeemable on their next exam, and periodically runs free or discounted exam promotions. Vouchers appear in the benefits section of your AWS Certification account and are applied at checkout when you schedule the exam. CloudCertPrep practice is always free regardless of any voucher.

What is the AWS Cloud Practitioner passing score?

The AWS Cloud Practitioner (CLF-C02) passing score is 700 on a scaled range of 100 to 1000. The score is scaled, not a simple percentage, because questions vary in difficulty, so you do not need 70% of questions correct exactly. Unscored pilot questions are mixed in and do not affect your result. Aim for 800+ on practice exams here for a comfortable margin.

Can I retake the AWS Cloud Practitioner exam if I fail?

Yes. If you do not pass, you can retake the CLF-C02 exam after a 14-day waiting period. There is no limit on the total number of attempts, but you must pay the exam fee each time and wait 14 days between attempts. Use the gap to review your weakest domains in domain practice here before rebooking.

Does the AWS Cloud Practitioner certification expire?

Yes. AWS certifications, including the Cloud Practitioner (CLF-C02), are valid for three years from the date you pass. To recertify, pass the current version of the same exam or earn a higher-level AWS certification before your credential expires, which automatically extends the foundational certification.

Is this the same exam as CLF-CO2, CLF-02, or CLF2?

Yes. The AWS Cloud Practitioner exam code is CLF-C02 (the current version, which replaced CLF-C01). It is sometimes mistyped as CLF-CO2, CLF-02, or CLF2 in searches. All refer to the same AWS Certified Cloud Practitioner exam that CloudCertPrep prepares you for.

Study strategy

How does the domain practice spaced repetition work?

For signed-in users, domain practice uses an adaptive algorithm based on your answer history. Questions you get wrong are weighted higher and appear more often. Questions you get right are weighted lower and appear less. Once you build a correct streak on a question, it enters an exclusion window and is hidden until enough time passes. Roughly 20% of each session is reserved for unseen questions so you keep covering new material. Guest sessions use random selection only.

What is the best way to prepare for AWS Cloud Practitioner?

In my experience, this is what works:

  1. Watch a free video course to build foundational knowledge. The freeCodeCamp CLF-C02 course on YouTube is excellent: https://www.youtube.com/watch?v=NhDYbskXRgc.
  2. Cross-reference the official AWS exam guide at https://docs.aws.amazon.com/aws-certification/latest/cloud-practitioner-02/cloud-practitioner-02.html, which is kept updated by AWS. Pay close attention to in-scope versus out-of-scope services.
  3. Use domain practice here to focus on weak areas with adaptive spaced repetition.
  4. Take full-length practice exams to build pacing and stamina.

After about a week of consistent practice with this method I finished the real exam in 20 minutes; the practice exams here prepare you well enough that the real one feels familiar.

Platform & certifications

What certifications does CloudCertPrep support?

CloudCertPrep currently supports AWS Certified Cloud Practitioner (CLF-C02) and AWS Certified AI Practitioner (AIF-C01). Additional certifications, including AWS Solutions Architect Associate (SAA-C03), are planned. The platform is multi-cert by design and new certifications can be added by the community.

Where can I report a wrong answer or bad question?

Open an issue on GitHub at https://github.com/nastaso/cloudcertprep/issues/new?template=report-question-error.yml.

Pull requests with corrections are welcome.

How can I contribute new questions or a new certification?

See CONTRIBUTING.md in the repository at https://github.com/nastaso/cloudcertprep. The question JSON schema is documented end-to-end.
