How to Prepare for the AWS Cloud Practitioner Exam (CLF-C02): A Beginner’s Study Guide
When I first looked at the AWS Cloud Practitioner exam, I had the same question most beginners have: where do I even start? AWS has hundreds of services, and the learning resources go on forever. I am preparing for this exam myself right now, so this guide is the plan I wish I had been given on day one. It’s simple, and it focuses on what the exam actually tests.
What the exam looks like
Before studying anything, it helps to know what you are walking into:
- 65 questions (multiple choice and multiple response). Only 50 of them are scored, and the other 15 are unscored questions AWS uses for testing. You will not know which ones they are.
- 90 minutes to finish.
- Passing score of 700 out of 1000.
- No coding and no hands-on tasks during the exam. It checks whether you understand cloud ideas and AWS services at a basic level.
What the exam covers (and how much)
The exam is split into four domains. The percentages below are from the official exam guide, and they should decide where your study time goes.
| Domain | What it covers | Weight |
|---|---|---|
| Domain 1: Cloud Concepts | Benefits of the AWS Cloud, Well-Architected Framework, cloud adoption ideas | 24% |
| Domain 2: Security and Compliance | Shared Responsibility Model, IAM, security services, compliance | 30% |
| Domain 3: Cloud Technology and Services | Compute, storage, databases, networking, and core AWS services | 34% |
| Domain 4: Billing, Pricing, and Support | Pricing models, cost tools, support plans | 12% |
Notice that Domain 3 and Domain 2 together make up about two-thirds of the exam. If you are short on time, put most of your energy there. Domain 4 is the smallest, but its questions tend to be the easiest marks to collect, so don’t skip it.
The modules I recommend, in order
Everything below is available on AWS Skill Builder.
1. Start with the Exam Prep Plan overview. The “Exam Prep Plan Overview” course takes about 15 minutes. It explains the four steps of the official plan and how long to spend on each.
2. Take the Official Practice Question Set. It has 20 questions and is free. Do it early, even if you feel unready. The point is to see how AWS words its questions, because the wording can be tricky.
3. Build your base with AWS Cloud Practitioner Essentials. This is a digital course of about 12 hours 45 minutes. It walks through the services, pricing, security, and architecture from zero. If you are new to AWS, do not skip this one. Spread it over a week instead of rushing it.
4. Review the domains in order of weight.
- Domain 3 first (the biggest)
- Domain 2 next
- Domain 1 after that
- Domain 4 last
Each Domain Review is a short video course made by AWS instructors. It is a good way to check that what you learned in Essentials actually stuck.
5. Take practice exams. Some of the practice content in the Exam Prep Plan, such as the Official Pretest and Official Practice Exam, requires a Skill Builder subscription. If you have access, use them. They show you how ready you really are. Try to score 80% or more before booking the real exam, so you have some safety margin above the 70% line.
Don’t just watch videos
My biggest tip is to touch the AWS Console while you study. Reading that S3 stores objects is one thing. Creating a bucket, uploading a file, and looking at the storage classes makes it stay in your head.
A few small things you can try:
- Open the IAM page and look at users, roles, and MFA settings.
- Create an S3 bucket and explore its settings.
- Open the Billing dashboard and set up a budget alert.
- Switch between Regions and notice how the available services change.
Just be careful with costs. Stay inside the free usage limits, delete resources you are not using, and set a budget alert before you experiment.
A simple way to remember each service
For every service you meet, write one line: what it does, and when you would use it. For example: “S3 stores files as objects, and is used for backups, static websites, and data storage.” The exam often gives you a short scenario and asks which service fits. One-line summaries make those questions much easier.
A rough study plan
If you can study around two hours a day, two to three weeks is realistic for a beginner:
- Week 1: Cloud Practitioner Essentials
- Week 2: Domain Reviews (3, 2, 1, 4) and notes
- Week 3: Practice questions, revising weak areas, and booking the exam
Everyone learns at a different speed, so adjust it to your life. A steady hour a day beats a long session once a week.
Final thoughts
The Cloud Practitioner exam is an entry-level certification, but it still needs real preparation. Learn the four domains, spend the most time where the marks are, practice in the console, and test yourself before exam day. If you stay consistent, it is very achievable, even if you are completely new to the cloud.
Good luck, and happy learning!
