A suggested study plan

Week 1Cloud concepts and the value of AWS; core global infrastructure
Week 2Security and compliance: the shared responsibility model, IAM basics
Week 3Core services: compute, storage, networking, databases
Week 4Billing, pricing and support; then timed review

The AWS Certified Cloud Practitioner (CLF-C02) is a foundational, mostly non-technical exam. It checks that you understand what the cloud is, the core AWS services, basic security, and how AWS pricing and support work. You do not need an engineering background. This guide is study guidance only, with no real or simulated exam questions.

The four domains, and how to study each

1. Cloud Concepts (24%)

The value of cloud computing (elasticity, pay-as-you-go, global reach), the AWS Cloud Adoption Framework, and basic economics. Focus on why organisations move to the cloud.

2. Security and Compliance (30%)

The shared responsibility model (the most-tested idea), IAM basics, and where to find compliance information. Be clear on what AWS secures versus what the customer secures.

3. Cloud Technology and Services (34%)

Recognise the core services by category: compute (EC2, Lambda), storage (S3), databases (RDS), and networking (VPC). You need to know what each is for, not how to configure it.

4. Billing, Pricing and Support (12%)

Pricing models (On-Demand, Reserved, Spot), the free tier, the pricing calculator, and the support plans. Small domain, easy marks.

How to prepare

Free AWS digital training plus the exam guide is usually enough. A little time in a free-tier account makes the services concrete, even though hands-on skill is not required. Avoid “exam dump” sites — they breach AWS policy and copyright.

Key concepts to master

Shared responsibility model
AWS secures the cloud; you secure what you put in it. Heavily tested.
Cloud value proposition
Trade capital expense for variable expense, elasticity, and global reach.
Core services
Recognise EC2, S3, RDS, VPC, Lambda and what each is for — at a high level.
Pricing models
On-Demand, Reserved and Spot; plus free tier and the pricing calculator.
Support plans
Basic, Developer, Business, Enterprise — know roughly what each includes.

FAQ

How long does Cloud Practitioner take to study?
Most people need 20–40 hours over two to four weeks. It is foundational with no hands-on requirement.
Is Cloud Practitioner worth it?
As a first credential or for non-technical roles, yes. Engineers aiming for cloud jobs often go straight to the Solutions Architect Associate.
Do I need to know how to code?
No. It tests cloud literacy, core services and concepts, not coding or deep configuration.
