The AWS Certified Cloud Practitioner (CLF-C02) exam is the doorway into Amazon Web Services. Pass it, and recruiters notice. Skip the prep, and you'll burn the $100 sitting fee on a coin flip. Most candidates who fail tell us the same thing afterwards: they read the official guide cover-to-cover but never took a full-length, timed practice exam. That's the trap this page exists to fix.

Below you'll find every free AWS Cloud Practitioner practice exam we host, plus the focused topic quizzes that target the four exam domains: Cloud Concepts, Security and Compliance, Cloud Technology and Services, and Billing, Pricing and Support. Each question carries a written explanation, so a wrong answer becomes a teaching moment rather than a guess.

If you're brand new to AWS, start with the cloud-concepts quizzes. They cover the shared responsibility model, the AWS Well-Architected Framework, regions and availability zones — the vocabulary that shows up in roughly a quarter of the real exam questions. More experienced candidates usually jump straight into the full 65-question simulations to gauge their score band.

One quick truth: the CLF-C02 is not a technical deep-dive. You won't be asked to write Lambda code or design a VPC. But you will be asked which AWS service fits a given business scenario, what the AWS Budgets tool actually does, and how the AWS Free Tier behaves after 12 months. Get comfortable spotting the right service from a one-paragraph use case and you're already most of the way there.

Here's a fact most prep guides skip. AWS publishes an official Exam Guide PDF for the Cloud Practitioner — it's six pages, and it lists every topic that could appear. Print it. Cross off each topic you've drilled with a practice quiz. The gaps that remain are your study list. This single trick saves more candidates than any course we've reviewed.

Another truth: the AWS Cloud Practitioner is the second most-taken AWS certification globally (just behind Solutions Architect Associate). Over 1.5 million candidates have sat it. The pass rate sits around 70 to 75% — meaning a quarter of attempts fail. That stat isn't meant to scare you. It's meant to remind you that 'easy entry-level cert' doesn't mean 'guaranteed pass'. Treat it with the same prep discipline you'd give a harder exam and you'll be in the top band.

That 700-out-of-1000 passing mark is scaled — meaning AWS does not publish a fixed percentage. In practice, candidates who score 75% on our full-length practice exam tend to clear the real thing. Scoring below 65% on multiple attempts? Slow down. Don't book the exam yet.

The 90-minute clock is generous for most people. The bigger risk is rushing through the first 20 questions, missing easy marks, and then spending 4 minutes on a single scenario question. Pacing matters more than knowledge for borderline candidates. Aim for roughly 70 seconds per question on the first pass, flag anything you're unsure about, and circle back.

You can take the exam at a Pearson VUE testing centre or via online proctoring. Online is convenient — but the proctor will make you pan your webcam around the room and may flag you for muttering. If you read out loud while thinking, book the in-person option instead.

Worth noting on the cost side: AWS sometimes runs discount promotions tied to specific events (re:Invent, AWS Summits, partner training programs). If your employer has an AWS Partner Network membership, ask them — partner organisations get exam vouchers at 50% off, and many don't use their full allocation. Even if you're studying solo, it's worth a 30-second LinkedIn search to see if a local AWS user group has a voucher pool.

One more pacing tip. The Pearson VUE interface lets you flag questions and review them at the end. Use that flag aggressively on your first pass. Anything that takes more than 90 seconds, flag it and move on. Most exam-takers find that 8 to 12 questions get flagged, and a calm second pass with 25 minutes remaining clears them up. Burning 4 minutes on a single question is how candidates fail the back half of the exam they could have aced.

One sneaky change: CLF-C02 puts more weight on cost-management services. Expect at least 6 to 8 questions on AWS Budgets, Cost Explorer, the Billing Dashboard, Savings Plans, and Reserved Instances. Candidates who skim the pricing domain ('I'm not in finance, why does this matter?') often lose 60 to 80 points right there. Don't be that candidate.

Another shift: scenario-based phrasing. Where CLF-C01 might have asked 'What is Amazon S3?', CLF-C02 asks 'A company needs durable object storage for archived logs that are rarely accessed but must be retrievable within hours. Which storage class is most cost-effective?' Same knowledge, harder framing. Practice exams calibrated to CLF-C02 train you for that framing — which is exactly why timed mock tests beat passive reading every time.

Notice the weighting: Cloud Technology and Security together make up 64% of the exam. That's where your practice time should go. Billing only carries 12% of the marks but it's also the easiest domain to score 100% in — the questions are concrete and the rules don't change. Treat it as low-hanging fruit.

The Security and Compliance domain trips up self-taught candidates the most. The shared responsibility model sounds simple — AWS handles security of the cloud, customers handle security in the cloud — but the real exam asks where specific tasks fall. Patching the operating system on an EC2 instance? Customer. Patching the hypervisor underneath that EC2 instance? AWS. Managed services like RDS shift more responsibility to AWS but never all of it. Drill these distinctions with the security-focused quizzes until they're automatic.

A worked example helps here. Consider this scenario question: 'A company hosts a public website on EC2 instances behind an Application Load Balancer. Who is responsible for patching the underlying physical hardware?' The answer is AWS — physical infrastructure always falls under 'security of the cloud'. But change it to 'Who is responsible for patching the operating system on those EC2 instances?' and the answer flips to the customer. Same architecture, opposite responsibility. Practice with a few dozen of these and the pattern becomes obvious.

Speaking of patterns: AWS loves to put 'most cost-effective' or 'least operational overhead' qualifiers in their scenario questions. When you see 'least operational overhead', the answer almost always points to a managed service (Lambda, RDS, Aurora Serverless, Fargate). When you see 'most cost-effective for predictable workloads', the answer points to Reserved Instances or Savings Plans. Learn these keyword-to-service shortcuts and you'll save 20 to 30 seconds on every scenario question.

The diagnostic-first approach feels backwards to people who haven't tried it. You're 'failing' before you've studied. But that failure is data. If you score 45% on the diagnostic and 80% of your wrong answers are in Security and Compliance, you now know exactly where to invest your next two weeks. Without the diagnostic, you'd probably skim every topic equally and end up at 65%. Targeted prep beats broad prep, every time.

How many practice exams should you take total? Most candidates who pass on the first try complete between 4 and 7 full-length mocks plus 15 to 25 topic quizzes. Less than 3 mocks and you'll be surprised by the question style on exam day. More than 10 and you're probably procrastinating the actual exam.

A second tactical point on mock exams: simulate exam conditions. That means no pausing, no checking your phone, no 'I'll just look up that one service real quick'. Sit through the full 90 minutes in one block. The first time most candidates do this, they're shocked at how mentally fatiguing it is. That fatigue is what tanks scores in the final 15 questions of the real exam. Train for it by replicating it.

If you score 90%+ on three consecutive full-length mocks, you're over-prepared and probably wasting study time. Book the exam this week. If you score 55 to 65%, you have real gaps — identify them and spend a focused week before retrying. Anywhere between 70 and 85%, you're in the realistic exam-ready band. Take one more mock, fix the wrong-answer themes, then go.

This matters more than most candidates realise. AWS isn't a static body of knowledge — services launch, deprecate, and rebrand all the time. AWS Lambda gained provisioned concurrency. Amazon Elastic Container Service got Fargate. The names and edge cases shift. Concept-level fluency means a new question phrasing doesn't throw you. Verbatim memorisation means it does.

That said, there's nothing wrong with reviewing exam-style questions repeatedly to internalise the AWS vocabulary. Just make sure you're rotating between sources. Our quizzes pull from a different question pool than most paid courses, so combining the two gives you broader coverage than either alone.

Beyond the CLF-C02, AWS offers a tier of Associate certifications: Solutions Architect Associate, Developer Associate, and SysOps Administrator Associate. If you're already comfortable in a technical role, some candidates skip the Practitioner and jump straight to Solutions Architect Associate. It's allowed — but the Practitioner gives you a quick, cheap win that proves to employers (and to yourself) that you understand the AWS ecosystem before tackling deeper material.

For job hunters, the Practitioner certification roughly matches what hiring managers expect from a candidate listing 'AWS exposure' on their CV. It's not a senior-level credential. But it does cleanly separate you from candidates who've only watched a few YouTube videos.

The 'employers value projects more' point cuts both ways. Yes, a working portfolio of AWS deployments beats a paper certificate — but most early-career candidates have neither. The Practitioner cert is the cheapest, fastest way to put something concrete on your CV that mentions AWS. Once you have the cert, build a small portfolio (deploy a static site to S3 + CloudFront, set up a Lambda triggered by an SQS queue) and you've covered both bases.

Renewal is the most common gripe. Three years feels short. AWS recently introduced free recertification through their Skill Builder digital training, which softens the blow — you can recertify by completing a course instead of re-sitting the full exam. Check the current AWS Certification policy before renewal time arrives.

Let's talk about the AWS services you genuinely need to know cold for the Cloud Practitioner exam. Compute: EC2, Lambda, Elastic Beanstalk, Lightsail, ECS, EKS, and Fargate. Know the use case for each — when would you pick Lambda over EC2? (Short bursts of code, event-driven, no server management.) When would you pick Elastic Beanstalk over plain EC2? (You want managed deployment but full server access.) Storage: S3 with its storage classes (Standard, Intelligent-Tiering, Glacier, Glacier Deep Archive), EBS, EFS, and Storage Gateway for hybrid setups.

Database: RDS, DynamoDB, Aurora, Redshift, ElastiCache. Networking: VPC, Route 53, CloudFront, Direct Connect. Security: IAM, Cognito, GuardDuty, Inspector, Macie, KMS, Secrets Manager, WAF, Shield. That last group is where most candidates lose marks — drill it.

The AWS Well-Architected Framework comes up in 4 to 6 questions on most exam sittings. Memorise the six pillars: Operational Excellence, Security, Reliability, Performance Efficiency, Cost Optimization, and Sustainability. The Sustainability pillar was added in late 2021 and many older study guides miss it — make sure your prep material includes it. Each pillar has a few design principles.

You don't need to recite all of them, but you should be able to identify which pillar a question is testing. If the question mentions 'reducing waste' or 'energy efficiency', it's Sustainability. If it mentions 'recovering from failure', it's Reliability. If it mentions 'minimising spend', it's Cost Optimization. Match the keyword to the pillar.

A note on the AWS support plans, because they're a guaranteed 2 to 3 exam questions. There are five tiers: Basic (free, included with every account), Developer, Business, Enterprise On-Ramp, and Enterprise. The pricing scales accordingly — Basic is free, Enterprise starts at $15,000 per month. The exam will ask you which support tier includes a Technical Account Manager (TAM). Answer: Enterprise On-Ramp gets a pool-based TAM, and Enterprise gets a dedicated TAM.

Business tier and below do not include a TAM. Another favourite question: which support tier includes 24/7 access to a Cloud Support Engineer via phone? Answer: Business, Enterprise On-Ramp, and Enterprise. Developer tier only gets business-hours email support. These details are dry but they're worth easy points.

If you're stuck choosing between study materials, here's our honest take. The official AWS Skill Builder Cloud Practitioner Essentials course is free and covers the syllabus end to end — start there. Stephane Maarek's Udemy course is the gold standard paid option, especially for visual learners.

Adrian Cantrill's video courses are deeper but probably overkill for the Practitioner level (save them for the Solutions Architect prep). Pair any of these with this site's free practice exams and you have everything you need. There's no need to spend more than $20 to $30 total on prep materials — anyone selling a $300 'guaranteed pass' bootcamp is overpricing.

Finally, the meta-advice that nobody tells you. The AWS Cloud Practitioner is a gateway, not a destination. Once you pass, you'll have access to a 50% discount voucher for your next AWS certification. Most candidates use it within 6 months to take the Solutions Architect Associate or Developer Associate. Plan your prep budget knowing that — the $100 you spend on the Practitioner becomes a $150 saving on the next exam. Cloud careers compound. Each certification you stack opens doors the previous one couldn't, and the Practitioner is the first door.

Here's the bottom line. The AWS Cloud Practitioner exam isn't easy, but it's beatable with the right prep. Skip the rote question banks. Take a diagnostic, target your weak domain, run timed mock exams every few days, and review every wrong answer until you can explain the concept out loud.

Use the practice tests on this page as your main calibration tool. They mirror the CLF-C02 question style without recycling leaked content, so your score on them is a fair signal of how you'll do on exam day. Aim for 75%+ across at least three different full-length mocks before booking the real thing. If you hit that, you're ready.

One last thing. Don't book the exam too far in advance. Most candidates who book three months out lose momentum somewhere in week 5. Once you're consistently scoring 75%+ on practice exams, book your test for 7 to 14 days later. The urgency will keep your prep sharp, and the material will still be fresh on test day. Good luck — go pass it.
