AWS Cloud Practitioner Study Guide

Review the main ideas in short, simple steps. Then test yourself on what you learned.

What to focus on first

  • Start with what cloud computing changes: pay for use, grow when needed and use managed services.
  • Learn the shared responsibility model: AWS secures the cloud; customers secure what they run and configure.
  • Connect common needs to services, such as object storage in S3 and virtual machines in EC2.
  • Understand Regions, Availability Zones and basic cost tools.
  • The official CLF-C02 guide defines which topics the real exam may cover.

Topics in this course

  1. Cloud concepts

    Explain why people choose cloud services: flexibility, elasticity and pay-as-you-go models. None of these guarantees zero cost or zero risk.

  2. Security

    AWS protects its infrastructure, while customers remain responsible for items such as data and configurations. The split depends on the service.

  3. AWS services

    Connect basic needs with services: EC2 for instances, S3 for object storage, RDS for managed relational databases and IAM for access.

  4. Pricing

    Estimate expenses before deploying. Review spending with AWS cost tools, and learn what drives compute and storage charges.

  5. Global infrastructure

    A Region is a geographical location with multiple Availability Zones. Multiple zones can improve resilience if designed correctly.

Sample practice with explanations

Which AWS service is commonly used for object storage?

Correct answer: Amazon S3

S3 stores objects such as files and backups.

Which service provides resizable virtual servers?

Correct answer: Amazon EC2

EC2 supplies compute instances in the cloud.

What is an AWS Region?

Correct answer: A geographic area with multiple Availability Zones

Regions group infrastructure in geographic areas.

Which AWS service handles identities and permissions?

Correct answer: AWS IAM

IAM controls access to AWS resources.

Under the shared responsibility model, who manages an EC2 guest operating system?

Correct answer: The customer

Customers generally manage guest operating systems on their EC2 instances.

Which AWS service helps estimate planned costs?

Correct answer: AWS Pricing Calculator

The AWS Pricing Calculator provides estimates based on chosen services and use.

What is one advantage of auto scaling?

Correct answer: Adjust compute capacity as demand changes

Auto scaling helps capacity match demand.
