AWS Certified Cloud Practitioner (CLF-C02) is unusual for what it deliberately leaves out: no architecture design, no CLI output to interpret, no labs. What makes it genuinely distinctive is not the absence of hands-on content — plenty of exams skip that — but who it is built for and where it sits in AWS's certification structure. It is AWS's single Foundational-tier credential, and it is explicitly designed as a mixed technical-and-business exam: the same 65 questions test whether a future Solutions Architect can name a compute service and whether a sales engineer or finance analyst understands what a Reserved Instance commitment actually costs.
This guide covers the exam mechanics — cost, format, scoring, retake rules, validity — and what actually shows up across the four domains. For the week-by-week study path, see the 4-week Cloud Practitioner study plan. For a fast final-review reference, see the Cloud Practitioner cheat sheet.
Who actually takes this exam
Most certification exams assume a technical candidate by default. Cloud Practitioner does not — AWS explicitly markets it toward both technical and non-technical roles, and the exam content reflects that on purpose rather than as an afterthought. Candidates who sit CLF-C02 in any given month include:
- Engineers new to AWS building toward Solutions Architect Associate or Developer Associate, using Cloud Practitioner as a low-risk first step.
- Sales engineers and account managers at AWS partners or AWS-using companies, who need to speak credibly about cloud concepts in client conversations without writing a line of infrastructure code.
- Project managers and program managers coordinating cloud migrations or AWS-based delivery teams, who need enough vocabulary to track scope and risk accurately.
- Finance, procurement, and support staff who touch AWS billing, budgets, or support-tier decisions without ever touching the AWS console directly.
- Students and career-changers building a first, low-cost technical credential before committing to a technical specialization.
This is a breadth exam by design: you need working familiarity with 20-plus AWS services well enough to recognize what each one is for, not how to configure it. It is conceptual, not hands-on — there is no equivalent of a CLI-output or YAML-interpretation question anywhere on CLF-C02, a level of abstraction you will not see again once you move to the Associate tier.
Where Foundational sits on AWS's four-tier ladder
AWS structures its certification program into four tiers, and Cloud Practitioner sits at the base of all of them: Foundational (Cloud Practitioner, AI Practitioner), Associate (Solutions Architect, Developer, SysOps Administrator), Professional (Solutions Architect Professional, DevOps Engineer Professional), and Specialty (networking, security, machine learning, and other narrow domains). The tiers are not just a difficulty label — the fee ladder tracks them directly: Foundational exams cost $100, Associate exams cost $150, and Professional and Specialty exams cost $300.
That structure matters for planning: Cloud Practitioner is not a prerequisite for anything else in the AWS catalog — you can sit SAA-C03 with zero prior AWS certifications — but it is the cheapest, lowest-risk way to confirm you have the conceptual footing before spending $150 and several weeks on an Associate-level exam that assumes you already know this material cold.
Exam format, cost, and scoring
The AWS Cloud Practitioner exam format is 65 questions in 90 minutes, delivered as multiple choice and multiple response, for a $100 fee:
| Property | Value |
|---|---|
| Questions | 65 (multiple choice + multiple response) |
| Time limit | 90 minutes |
| Cost | $100 USD |
| Passing score | 700 / 1000 (scaled) |
| Delivery | Pearson VUE test center or OnVUE online proctoring |
| Validity | 3 years |
| Result | Pass/fail shown on-screen immediately; official score report within 5 business days |
| Languages | English, Japanese, Korean, Simplified Chinese, and several others |
90 minutes for 65 questions is about 83 seconds each — tighter than it sounds once you hit the scenario-style questions that run three or four sentences. Unlike some vendors, AWS publishes the passing score outright: 700 out of 1000, a scaled score rather than a raw percentage, converted through a statistical model AWS does not fully disclose. Some of the 65 questions are unscored, gathering data for future exam versions without telling you which ones — treat every question as if it counts. CertSharp's recommendation: score consistently above 85 percent on full-length timed mocks before booking, since the scaled conversion is not linear and a comfortable margin protects you from a bad scaling day.
No labs, no simulations — just multiple choice
CLF-C02 uses exactly two question formats, and nothing else:
- Multiple choice. The dominant format — a scenario or definitional stem, four options, one correct answer.
- Multiple response. The stem says “select TWO” (occasionally three). Five or more options, exactly two or three correct. You must select the full correct set to earn the point — there is no partial credit.
There are no labs, no simlets, no CLI output to interpret, and no drag-and-drop items on Cloud Practitioner — a deliberate design choice that keeps the exam accessible to non-technical candidates. That level of hands-on, environment-based testing does not appear anywhere in the AWS catalog until the Associate tier, and even then it is limited compared to some other vendors' simulation-heavy formats. If you are coming to CLF-C02 worried about a lab component, you can stop worrying — it simply does not exist on this exam.
The four domains: technical meets business
AWS publishes four domains with their relative weights:
| # | Domain | Weight | ~Questions |
|---|---|---|---|
| 1 | Cloud Concepts | 24% | ~16 |
| 2 | Security and Compliance | 30% | ~20 |
| 3 | Cloud Technology and Services | 34% | ~22 |
| 4 | Billing, Pricing, and Support | 12% | ~8 |
Domain 4 is where the exam's mixed audience becomes obvious: pricing models, support-plan tiers, and billing tools are exactly the vocabulary a non-technical stakeholder needs, and AWS gives it real exam weight rather than treating it as filler. Domain 3 carries the largest weight overall — this is where the “name that service” questions live, covering compute, storage, networking, and database options. Domain 2 is close behind, and it is where most first-time candidates lose points: the shared responsibility model is tested from several angles, and it is easy to misjudge where AWS's responsibility ends and yours begins. For the concept in full, see AWS Shared Responsibility Model Explained.
Test center vs OnVUE online
Both delivery methods produce the same exam content and the same pass/fail outcome.
Pearson VUE test center is in-person. You arrive with valid ID, store your belongings in a locker, and sit at a provided workstation while the center staff proctor in person.
OnVUE online proctoring lets you test from home. You install the OnVUE application, complete an ID check and room scan on camera, and a remote proctor monitors you for the full 90 minutes. You need a stable connection, a single monitor, and a private room with a clear desk.
Which to choose: OnVUE saves travel time and is available around the clock in most regions, but any connectivity hiccup or background noise can trigger a proctor intervention. If your home setup is not private and quiet, book a test center slot instead — it removes that variable entirely.
Registering, ID rules, and rescheduling
- Create or sign in to your AWS Certification account.
- Select AWS Certified Cloud Practitioner and choose “Schedule this exam.”
- Pick a delivery method: Pearson VUE test center or OnVUE online.
- Choose an available date and time slot — OnVUE slots run 24/7 in most regions.
- Pay the $100 fee (or apply a voucher code if you have one).
- Save the confirmation email; it has your exam appointment details and any pre-exam requirements.
You can reschedule for free up to 24 hours before your appointment. Inside that window, you forfeit the exam fee.
You need government-issued photo ID that matches the name on your AWS Certification account exactly. Test centers may ask for a second form of ID; OnVUE typically accepts one primary ID plus the on-camera identity verification built into the check-in flow. For OnVUE, check-in opens 30 minutes before your slot, and expect a full room scan (walls, desk, ceiling) via your webcam — clear your desk completely and remove watches, headphones, and any second screen. For test centers, arrive at least 15 minutes early; late arrivals beyond the grace period forfeit the appointment.
The flat 14-day retake rule
If you fail CLF-C02, AWS applies a flat 14-day wait before you can retake it — and that wait does not escalate with repeated failures, unlike some other vendors that lengthen the wait after a second or third fail. There is no cap on total lifetime attempts. Each retake costs the full $100 fee. AWS sends a section-level score breakdown after a fail, so use the wait to drill your weakest domain rather than re-studying everything evenly.
Validity and recertifying without retaking
Cloud Practitioner is valid 3 years from the pass date — shorter than some competing foundational credentials (Microsoft's AZ-900, for comparison, does not expire at all). Recertify by retaking the current version of CLF-C02 within the renewal window, or extend your certified status early by passing a higher-level AWS certification before your Cloud Practitioner credential expires — for example, passing Solutions Architect Associate resets your 3-year clock without sitting CLF-C02 again. This matters for planning: if you intend to climb the AWS ladder anyway, your natural progression to Associate-level certs keeps you continuously certified without a separate Cloud Practitioner retake.
Prerequisites and recommended experience
Cloud Practitioner has no formal prerequisites and no required prior AWS certification. AWS recommends 6 months of foundational AWS Cloud exposure in any role — this can be hands-on, or it can be exposure through working alongside teams that use AWS.
If you have zero cloud background, plan on 3-4 weeks of focused study. If you already work with AWS in a non-certified capacity, 1-2 weeks of terminology and service-mapping review is often enough.
Cloud Practitioner vs other AWS certs
| Certification | Tier | Cost | Best For |
|---|---|---|---|
| Cloud Practitioner | Foundational | $100 | Anyone new to AWS, non-technical roles |
| AI Practitioner | Foundational | $100 | AI/ML-curious roles, product and business staff |
| Solutions Architect Associate | Associate | $150 | Engineers designing AWS architectures |
| Developer Associate | Associate | $150 | Developers building on AWS SDKs |

Frequently asked questions
How much does the AWS Cloud Practitioner exam cost?
The AWS Certified Cloud Practitioner (CLF-C02) exam costs $100 USD, and that fee is identical whether you sit it at a Pearson VUE testing center or take it online with OnVUE proctoring — location does not change the price. This $100 fee sits at the bottom of AWS's certification fee ladder: Associate-level exams like Solutions Architect Associate cost $150, and Professional and Specialty exams cost $300, so Cloud Practitioner is deliberately priced as the cheapest entry point into the program. AWS occasionally issues 50%-off exam vouchers through re/Start, AWS Educate, university partnerships, or conference attendance, but there is no standing discount for individual candidates who register without one. Pearson VUE converts the price to local currency at checkout outside the US, and local VAT or sales tax may apply on top of the base fee depending on your country, so budget slightly above $100 if you are testing internationally.
How many questions are on the AWS Cloud Practitioner exam?
The exam has 65 questions and a 90-minute time limit, which works out to roughly 83 seconds per question on average — tighter than it sounds once scenario-style questions running three or four sentences enter the mix. Not every question counts toward your score: AWS mixes in unscored questions to gather statistics for future exam versions, but it never discloses which ones, so the only safe strategy is to treat all 65 as if they count and pace yourself accordingly. The questions are split between two formats, multiple choice (one correct answer from four options) and multiple response (select two or three correct answers from five or more, with no partial credit for a partially correct selection). A common pacing tactic is to move quickly through recall-style questions — service names, pricing definitions, support-tier facts — to bank extra time for the handful of genuinely multi-step scenario questions that eat more of the clock.
What is the passing score for AWS Cloud Practitioner?
AWS publishes an exact passing score for CLF-C02: 700 out of a possible 1000, on a scaled scoring system where your raw count of correct answers is converted through a statistical model that AWS does not publish in detail — so 700 does not simply mean "70% of questions right," and the exact number of questions you need correct can vary slightly between exam forms. Because some questions are unscored and invisible to you, and because the scaling is not linear, a score that looks comfortably above 700 on paper can still represent less margin than it appears to. CertSharp recommends scoring consistently above 85% on full-length, timed 65-question practice exams before booking your real exam date — that buffer protects you from a less favorable scaling outcome on exam day itself, rather than banking on a bare pass at the published cut score.
Is the AWS Cloud Practitioner exam open book?
No. CLF-C02 is entirely closed book under proctored conditions, whether you sit it in a Pearson VUE test center or online via OnVUE — there is no tier or delivery method that allows reference material. You cannot use notes, a textbook, a second monitor, a phone, smartwatch, or any other reference material during the 90-minute session, and being caught with any of these can result in the exam being invalidated. This is standard across every AWS certification exam, not something specific to the foundational tier, so do not expect it to loosen at the Associate or Professional level either. Because the exam is closed book, the practical implication for study is that you need genuine recall of service names, pricing models, and the shared responsibility model rather than the ability to look concepts up mid-exam — plan your preparation time accordingly rather than relying on a cheat sheet during the actual test.
Can I take the AWS Cloud Practitioner exam online?
Yes. AWS offers OnVUE online proctoring for CLF-C02 in most countries, and it produces exactly the same certification outcome as testing in person — there is no "online" asterisk on the credential itself. You need a working webcam, a stable internet connection, and a private room with a clear desk; the proctor performs a full room scan before you begin and then monitors you continuously via webcam and microphone for the entire 90 minutes. Test centers remain available in every region as the alternative, and they remove connectivity and environment variables entirely, which matters if your home setup is shared, noisy, or lacks a reliable connection. Some countries restrict online proctored testing for regulatory reasons, in which case a test center is your only option — check availability for your specific location during registration rather than assuming OnVUE is universally offered.
How long is the AWS Cloud Practitioner certification valid?
AWS certifications, including Cloud Practitioner, are valid for 3 years from the pass date, after which the credential lapses unless you take action before it expires. You can recertify by simply retaking the current version of CLF-C02 within your renewal window, or you can extend your certified status early by passing any higher-level AWS certification (an Associate, Professional, or Specialty exam) before the 3-year window closes — that higher cert resets the clock without requiring a separate Cloud Practitioner retake. This 3-year cycle is shorter than some competing foundational credentials: Microsoft's Azure Fundamentals (AZ-900), for comparison, does not expire at all once passed. If you plan to climb the AWS certification ladder anyway, your natural progression toward Associate-level certs will likely keep you continuously certified without ever needing to sit CLF-C02 a second time.
What is the AWS Cloud Practitioner retake policy?
If you fail CLF-C02, AWS requires a flat 14-day wait before you can retake it, and that same 14-day rule applies to every subsequent attempt — it does not escalate the longer you go without passing, unlike some vendors that impose longer waits after a second or third failure. There is no cap on total lifetime attempts, but you pay the full $100 fee every single time you sit the exam, so repeated attempts add up quickly in both cost and lost study momentum. AWS sends a section-level score breakdown after a failed attempt, showing roughly how you performed in each of the four domains without revealing which specific questions you missed — use that two-week window to drill your weakest domain specifically rather than restudying everything evenly, since undirected review rarely fixes the actual gap that caused the fail.
