A. Reserved Instances

B. Dedicated Hosts

C. Spot Instances ✓

How to pass the AWS Cloud Practitioner

Understand services, don't memorize them

Focus on the ~50 most common services — EC2, S3, RDS, Lambda, IAM, VPC, CloudFront, Route 53, CloudWatch. Know their purpose, not their implementation details.

The Shared Responsibility Model is critical

Know clearly: AWS handles the cloud infrastructure; you handle the configuration, data, and access controls inside it. When in doubt: hardware or facility → AWS. Configuration or data → Customer.

Learn the pricing models

On-Demand, Reserved, Savings Plans, Spot, and Dedicated — know when each makes sense. Spot = fault-tolerant workloads. Reserved = steady-state. Savings Plans = flexible commitment.
