The CLF-C02 exam guide organizes AWS Cloud Practitioner around four domains. Cloud Concepts is 24% of scored content, Security and Compliance is 30%, Cloud Technology and Services is 34%, and Billing, Pricing, and Support is 12%. The weights show that AWS service knowledge and security basics deserve the most attention.
What each domain covers
- Cloud Concepts: cloud value, design principles, migration value, and the AWS global infrastructure.
- Security and Compliance: shared responsibility, identity, access, governance, compliance, and security services at a high level.
- Cloud Technology and Services: common AWS service categories, use cases, deployment concepts, and management tools.
- Billing, Pricing, and Support: pricing models, cost tools, support options, and account/billing concepts.
Use these domains as a scorecard when you review the AWS Cloud Practitioner Practice Test. If you miss service-selection questions, study the service family rather than a single product. If you miss cost questions, review billing tools and pricing models. The study guide gives a practical order for that review.
Do not ignore billing and support
Billing, pricing, and support is the smallest domain, but it can be the easiest place to lose points if you only study technical services. Review cost allocation, pricing models, account tools, support options, and when a customer would use AWS cost-management features.
A useful way to review is to ask one plain question per domain: why cloud, who secures what, which service family fits, and how cost/support works. If you can answer those four questions in your own words, practice questions become much easier to interpret.
