The AWS Certified Cloud Practitioner (CLF-C02) is a 90-minute, 65-question foundational exam that costs $100 and tests your high-level understanding of AWS Cloud services, security, and billing concepts. You need a scaled score of 700 out of 1,000 to pass, the credential stays valid for three years, and AWS does not require any prior IT experience or hands-on cloud work to sit for it. The exam is the standard entry point into the AWS certification portfolio for career changers, sales and project-management staff, and anyone who needs foundational cloud literacy without designing architectures.
What the CLF-C02 Exam Covers
The current exam version, CLF-C02, replaced the earlier CLF-C01 version and remains current as of 2026. AWS organizes the assessment around four content domains, each weighted to reflect what a cloud-literate professional needs to understand. Cloud Technology and Services is the largest domain at 34%, followed by Security and Compliance at 30%, Cloud Concepts at 24%, and Billing, Pricing, and Support at 12%. The domain weightings tell you where to spend study time: nearly two-thirds of scored questions come from Technology and Security combined.
| Domain | Weight | Focus Areas |
|---|---|---|
| Cloud Concepts | 24% | Cloud value proposition, Well-Architected Framework, migration strategies, cloud economics |
| Security and Compliance | 30% | Shared responsibility model, IAM, encryption, compliance programs, incident response |
| Cloud Technology and Services | 34% | Compute, storage, networking, database, AI/ML and analytics service identification |
| Billing, Pricing, and Support | 12% | Pricing models, cost management tools, AWS Support tiers, technical resources |
The questions are conceptual rather than scenario-heavy. You identify which AWS service fits a described use case, explain how the shared responsibility model divides obligations between AWS and the customer, and recognize core billing tools such as AWS Pricing Calculator, AWS Budgets, and Cost Explorer. Unlike the Solutions Architect Associate exam, CLF-C02 does not ask you to design architectures or make trade-off decisions under constraints — it verifies that you can describe and position services accurately.
Within Cloud Technology and Services, expect questions on the compute family — EC2 for virtual machines, Lambda for serverless functions, and ECS and EKS for containers. Storage questions center on S3 object storage, EBS block volumes, and the various S3 storage classes. Networking coverage includes VPC, subnets, route tables, and CloudFront content delivery. Database items contrast managed relational databases through RDS and Aurora with NoSQL options such as DynamoDB. The domain also introduces analytics services like Athena and QuickSight, plus artificial intelligence and machine learning services including Amazon SageMaker, Comprehend, and Rekognition.
Exam Format and Passing Score
The exam presents 65 questions in 90 minutes, but only 50 are scored; the remaining 15 are unscored items AWS uses to evaluate future questions, and they are not identified on the test. Every question is either multiple choice — one correct answer from four options — or multiple response — two or more correct answers from five or more options. Unanswered questions count as incorrect, so there is no penalty for guessing and you should never leave a blank.
AWS scores the exam on a compensatory model: your overall scaled score must reach 700 out of 1,000, but you do not need to pass each domain individually. A strong performance in Technology can offset a weaker result in Billing. The compensatory model rewards candidates who concentrate on high-weight domains rather than trying to achieve equal mastery everywhere.
A Practical Study Strategy
AWS recommends up to six months of AWS Cloud exposure, but structured preparation lets most candidates pass in four to six weeks. The four-step prep plan AWS publishes — review the exam guide, take the free official practice question set, fill knowledge gaps with AWS Skill Builder courses and Cloud Quest, then assess readiness with the official practice exam — is a reliable scaffold that mirrors how the domains are weighted.
The most efficient study sequence combines three elements in parallel: a comprehensive video course for conceptual coverage, hands-on time in a free-tier AWS account for retention, and timed practice exams to calibrate readiness. Aim for consistent scores of 75% or higher on practice tests before booking the real exam. A focused final-week checklist:
- Memorize the four domain weightings and the shared responsibility model
- Learn the core service categories: EC2, Lambda, S3, EBS, VPC, RDS, DynamoDB
- Practice identifying the correct AWS service for common use cases
- Review pricing models: On-Demand, Reserved, Spot, and Savings Plans
- Drill billing and support tools: Cost Explorer, Budgets, Trusted Advisor, Support tiers
Free AWS resources cover most of the exam scope. AWS Skill Builder offers a no-cost Cloud Practitioner learning plan with roughly 15 hours of video content, and AWS Cloud Quest: Cloud Practitioner provides a gamified, interactive environment for practicing service selection. The official practice question set is free and mirrors the exam format closely enough to use as a readiness benchmark. Paid options — instructor-led courses, third-party practice exams, and exam simulators — add value mainly through question volume and detailed explanations, but they are optional if you combine the free official materials with consistent hands-on practice.

Cost, Registration, and Renewal
The exam fee is $100 USD regardless of whether you test at a Pearson VUE center or online with proctoring. Once you hold any active AWS certification, AWS grants a 50% discount on your next exam, which makes the Cloud Practitioner an economical first credential — it reduces the cost of every subsequent Associate or Professional exam you take. Many employers reimburse certification costs through professional-development budgets, so verify that benefit before paying out of pocket.
Registration is handled through Pearson VUE. Testing-center slots are typically available within one to two weeks, and online proctoring requires a private room, a working webcam, and a stable internet connection; the proctoring software locks your browser for the entire session. The credential is valid for three years. To renew, you can pass the current Cloud Practitioner exam again, pass any Associate-level or Professional-level AWS exam, or complete the AWS Cloud Quest recertification path. Earning a higher-level certification automatically recertifies the Cloud Practitioner, making advancement the most efficient renewal route if you plan to continue on the AWS track.
