The AWS Certified Cloud Practitioner (CLF-C02) exam contains 65 questions to be completed in 90 minutes. Of those 65 questions, 50 are scored and 15 are unscored experimental questions that AWS uses to evaluate potential future exam items. You cannot distinguish between scored and unscored questions during the exam, so you must answer all 65 with equal effort. The passing score is 700 out of 1,000 on a scaled scoring system.
As AWS's foundational-level certification, the Cloud Practitioner exam is designed to be accessible to professionals from all backgrounds — not just engineers. Business analysts, project managers, sales teams, and career changers all regularly take this exam. Understanding the exact format, question distribution, and time management strategies gives you a significant advantage on exam day.
The AWS Cloud Practitioner exam uses two question formats:
There are no performance-based questions (PBQs), simulations, or hands-on labs. The entire exam is knowledge-based. You can flag questions and return to them at any point before submitting — unlike the CISSP (which uses adaptive testing and does not allow backtracking), the AWS Cloud Practitioner gives you full flexibility to review and change answers.
The CLF-C02 exam blueprint is divided into four domains with specific weightings:
| Domain | % of Exam | ~Scored Questions | Key Topics |
|---|---|---|---|
| Cloud Concepts | 24% | ~12 | Value proposition of AWS, cloud economics, migration strategies, Cloud Adoption Framework |
| Security & Compliance | 30% | ~15 | Shared responsibility model, IAM, encryption, compliance programs, AWS security services |
| Cloud Technology & Services | 34% | ~17 | Compute (EC2, Lambda), storage (S3, EBS), networking (VPC), databases (RDS, DynamoDB) |
| Billing, Pricing & Support | 12% | ~6 | Pricing models, AWS Free Tier, Cost Explorer, support plans, AWS Organizations |
Domain 3 (Cloud Technology & Services) at 34% carries the most weight. Expect questions about when to use which AWS service, the difference between compute options (EC2 vs Lambda vs ECS), storage tiers (S3 Standard vs S3-IA vs Glacier), and database choices (RDS vs DynamoDB). Domain 2 (Security & Compliance) at 30% is the second most tested — master the shared responsibility model, IAM best practices, and encryption options.
With 90 minutes for 65 questions, you have approximately 83 seconds per question. This is relatively generous compared to most certification exams, giving you time to read scenarios carefully and consider each option. However, some questions involve lengthy service descriptions that require careful reading.
AWS Cloud Practitioner questions frequently follow these patterns:
| Certification | Provider | Questions | Time | Cost | Passing Score |
|---|---|---|---|---|---|
| AWS Cloud Practitioner (CLF-C02) | Amazon | 65 | 90 min | $100 | 700/1000 |
| Azure Fundamentals (AZ-900) | Microsoft | 40-60 | 85 min | $99 | 700/1000 |
| Google Cloud Digital Leader | 50-60 | 90 min | $99 | 70% | |
| CompTIA Cloud+ | CompTIA | 90 | 90 min | $369 | 750/900 |
The AWS Cloud Practitioner is the most popular entry-level cloud certification due to AWS's dominant market share (over 30% of the global cloud market). If you are unsure which cloud platform to start with, AWS gives you the broadest job market applicability.
The AWS Cloud Practitioner exam costs $100 USD, making it one of the most affordable professional certifications available. Here are key cost details:
| Experience Level | Study Time | Approach |
|---|---|---|
| IT professional with cloud exposure | 1-2 weeks (10-20 hours) | Review exam guide, take practice tests, focus on weak areas |
| IT professional without cloud experience | 2-4 weeks (20-40 hours) | Complete AWS Cloud Practitioner Essentials + practice tests |
| Career changer / complete beginner | 4-6 weeks (40-60 hours) | Start with cloud computing basics, then AWS-specific training |
While the exam covers 60+ AWS services at a high level, these appear most frequently:
The CLF-C02 exam contains 65 questions (50 scored + 15 unscored experimental questions) to be completed in 90 minutes.
700 out of 1,000 on a scaled scoring system. This roughly translates to answering about 70% of scored questions correctly.
Yes. 15 of the 65 questions are unscored experimental questions. You cannot identify which ones are unscored, so answer all 65 with equal effort.
Yes. AWS exams allow you to flag questions and revisit them at any time before submitting your final answers.
Multiple-choice (one correct from four) and multiple-response (two or three correct from five or six). No PBQs, simulations, or hands-on labs.
Most candidates consider it one of the easier cloud certifications because it tests breadth rather than depth. With 2-4 weeks of focused study, most pass on their first attempt.
$100 USD. AWS frequently offers 50% discount vouchers to candidates who complete free training paths on AWS Skill Builder.
Most candidates need 2-4 weeks (20-40 hours). Those with existing IT experience may need less, while complete beginners should allow 4-6 weeks.
