Everything you need for the CLF-C02 exam — format, cost, what it tests, booking, renewal and a step-by-step preparation plan for first-time candidates.
The AWS Certified Cloud Practitioner (exam code CLF-C02) is Amazon Web Services' foundational certification: 65 questions, 90 minutes, $100 USD, no prerequisites, and a scaled passing score of 700 out of 1000. It validates a broad, non-specialist understanding of the AWS Cloud — what the major services do, how AWS pricing and support work, and how security responsibilities are shared between you and AWS. This guide covers the exam itself from end to end: what it tests, how it is structured, what it costs, how to register, and a realistic preparation plan.
One scope note before we start. This article is the exam reference. If you are still deciding whether the certificate is a sensible investment for your situation, that question has its own dedicated analysis in Is AWS Cloud Practitioner Worth It?, and the "should I skip it and go straight to an Associate exam" debate is handled in AWS Cloud Practitioner vs Solutions Architect.
AWS Certified Cloud Practitioner is the entry point of the AWS certification portfolio, which as of 2026 runs across four levels: Foundational, Associate, Professional and Specialty. Cloud Practitioner sits at the Foundational level alongside the newer AWS Certified AI Practitioner. It is deliberately breadth-first — designed for people who need to understand the AWS Cloud rather than build on it daily, which is why it attracts project managers, sales and finance staff, students, and career changers as well as junior technical candidates.
The current exam version is CLF-C02, which has been in force since September 2023. As of August 2026, AWS has not announced a CLF-C03, so CLF-C02 is the version you will book. Always confirm the live version on the official Cloud Practitioner page before scheduling, because AWS retires exam versions on published timetables.
AWS positions the certification for candidates with up to around six months of general exposure to the AWS Cloud — and that exposure can be indirect. You do not need to have deployed anything. A business analyst who sits in architecture meetings, a recruiter screening cloud CVs, or a graduate who has completed a cloud fundamentals course all fit the intended profile. There are no formal entry requirements at all: the experience guidance is a recommendation, not a rule.
If your goal is a hands-on technical role and you are choosing your very first AWS certificate, the decision between starting here or elsewhere is covered in Best AWS Certification for Beginners — this guide assumes you have already settled on CLF-C02.
Here is the exam at a glance, per AWS's official certification page as of August 2026:
A few of these numbers deserve unpacking.
The 700 passing mark is a scaled score, not a percentage. AWS converts your raw performance onto a 100–1000 scale so that results are comparable across different exam forms of varying difficulty. That means you cannot translate 700 into "I need 70% of questions correct" — the conversion is not published, and AWS does not publish pass rates either. Treat any pass-rate figure you see on forums as guesswork. The practical takeaway: aim to be comfortably strong across the whole syllabus rather than calculating a minimum-effort threshold.
There is no penalty for wrong answers, so never leave a question blank. An unanswered question and a wrong answer cost you exactly the same.
CLF-C02 is delivered through Pearson VUE, either at a physical test centre or online from home or an office. Online proctoring requires a quiet, private room, a webcam check-in and an uninterrupted session — no one may enter the room, and you cannot leave it. If your home environment cannot guarantee that for 90 minutes, book a test centre; a knock on the door at the wrong moment can void an online session. Availability of appointment slots differs by region, so check both options before assuming one is faster.
AWS offers the exam in multiple languages, but versions do change: the Indonesian-language version of CLF-C02, for example, retires after 16 July 2026. If you plan to test in a language other than English, verify current availability on the official exam page when you book.
AWS publishes an official CLF-C02 exam guide (a free PDF linked from the certification page) that lists the exam's content domains, their weightings, and the specific task statements you are accountable for. Download it before you open any course — it is the single document the exam is written against, and the weightings tell you where to spend your study hours. Rather than reproduce a list that AWS may revise, here is what the tested territory means in practice.
Cloud concepts and value. Expect questions on why organisations move to the cloud at all: trading capital expense for variable expense, elasticity versus fixed capacity, high availability across Availability Zones and Regions. These questions are conceptual — you will be asked to recognise which benefit or design principle a scenario describes.
Security and the shared responsibility model. The single most examinable idea at this level is the split between what AWS secures (the infrastructure, "security of the cloud") and what the customer secures (their data, identities and configurations, "security in the cloud"). You should be able to place any given task — patching a managed database engine, setting an S3 bucket policy, physical data-centre access — on the correct side of that line, and know what AWS Identity and Access Management (IAM) users, groups, roles and policies are for.
Core technology and services. You need recognition-level knowledge of the flagship services: what Amazon EC2, Amazon S3, Amazon RDS, AWS Lambda and Amazon VPC are for, and which category of problem each solves. CLF-C02 does not ask you to configure anything — it asks you to pick the right tool. "A company wants to run code without managing servers" should ring the Lambda bell instantly.
Billing, pricing and support. Cloud Practitioner is unusual among IT certifications in how seriously it treats money. Understand the general pricing models (on-demand versus commitment-based savings), the tools AWS provides for tracking and forecasting spend, and how the AWS Support plan tiers differ. Candidates from technical backgrounds routinely under-prepare here because it feels non-technical; the exam guide says otherwise.
One format reassurance: CLF-C02 questions are multiple choice and multiple response only. There are no labs and no essay questions, and the newer ordering, matching and case-study question types AWS introduced in 2024 debuted on its AI exams (AIF-C01 and MLA-C01), not on Cloud Practitioner — the official page still lists the classic two types.
There is no single right number of study hours — it depends on how much AWS exposure you already have — so this plan is sequenced by milestones rather than weeks. Complete each step before moving on.
Your certification is valid for three years. AWS gives you several renewal routes: retake the current Cloud Practitioner exam, pass any Associate or Professional level exam (which renews Cloud Practitioner automatically), or use AWS Cloud Quest: Recertify Cloud Practitioner — a game-based renewal path listed on AWS's recertification page as of August 2026. The Cloud Quest option's availability has been described inconsistently by AWS in the past, so check the recertification page for its current status when your window approaches rather than relying on it years in advance.
Two further benefits are worth knowing. First, once you hold any active AWS certification, AWS issues a 50% discount voucher for your next exam — so a $150 Associate exam effectively costs $75 if you sit it while your Cloud Practitioner is active. Second, the credential slots naturally under every later AWS certificate: the knowledge is assumed, even where the certificate is not required. Where Cloud Practitioner fits into a longer certification sequence for your specific career goal is mapped out in the AWS Certification Roadmap for 2026.
Yes. There are no prerequisites, and AWS's "up to six months of exposure" is guidance, not a gate. Plenty of candidates pass from courses plus a small amount of Free Tier experimentation. Expect to need more study time than someone who works alongside AWS daily, and lean harder on hands-on console practice to make the concepts concrete.
AWS does not say. Because scoring is scaled from raw marks onto the 100–1000 range and the conversion varies by exam form, there is no fixed number of allowable mistakes. Any "you can miss X questions" claim you read online is unverified. Aim for consistent, comfortable practice-test performance across every domain instead.
Pearson VUE and AWS handle result delivery, and the mechanics can change — check the current policy in your AWS certification account when you book. What is certain: your official score report shows your scaled score, and your certification, once earned, appears in your AWS certification account with a three-year validity period.
No. CLF-C02 consists of multiple-choice and multiple-response questions only. No current AWS certification exam includes a lab component.
If you have read this far, the honest next action is simple: download the official CLF-C02 exam guide from AWS, block out your study calendar, and start step one of the plan above. The exam is genuinely passable for a prepared newcomer — 65 questions, 90 minutes, foundational depth — and everything it tests is publicly documented. When your course is done and you want to know whether you are ready, benchmark with a timed practice run before you spend the $100, and browse the wider Amazon certification exams hub to see where your preparation can go after this first credential.
