AWS Certified Cloud Practitioner: Skills Measured

AWS lists four CLF-C02 domains: Cloud Concepts, Security and Compliance, Cloud Technology and Services, and Billing, Pricing, and Support. The official guide weights them at 24%, 30%, 34%, and 12% of scored content respectively. Use those official domains to organize study time and keep local practice results separate from exam weighting.

Cloud Concepts covers why cloud is used: elasticity, scalability, agility, high availability, global infrastructure, economies of scale, and pay-as-you-go pricing. You should recognize Regions, Availability Zones, edge locations, the AWS Cloud Adoption Framework, and the Well-Architected Framework at a high level.

Security and Compliance starts with the Shared Responsibility Model. Know what AWS secures and what the customer secures. Then connect IAM, MFA, root user protection, security groups, CloudTrail, AWS Organizations, AWS Artifact, encryption basics, and compliance resources to common exam scenarios.

Cloud Technology and Services is service recognition. EC2 provides virtual servers, Lambda provides serverless functions, S3 provides object storage, EBS provides block storage, RDS provides managed relational databases, DynamoDB provides NoSQL storage, VPC provides isolated networking, CloudFront provides content delivery, and Route 53 provides DNS.

Billing, Pricing, and Support covers cost and assistance tools. Know the difference between Pricing Calculator, Cost Explorer, AWS Budgets, consolidated billing, Reserved Instances, Savings Plans, Trusted Advisor, AWS Health Dashboard, and Support Plans. These questions usually ask which tool or plan fits a stated need.
