About CLF-C02
The entry point to AWS certification. It checks that you can explain what the cloud is for, what the main AWS services do, who is responsible for what under the shared responsibility model, and how AWS charges for things. It is broad and shallow: no architecture diagrams, no CLI.
Who it's for. People in sales, finance, project or management roles who work around AWS, and engineers who want a quick first badge before an associate exam.
How to prepare
- Billing is the smallest domain but the easiest to lose marks on. Know the support plans and what each one adds, and when to use Savings Plans, Reserved Instances or Spot.
- For shared responsibility questions, ask who can physically touch the thing. AWS patches the hypervisor. You patch the guest OS on EC2.
- Learn services in pairs that get confused: CloudTrail vs CloudWatch, Shield vs WAF, Inspector vs GuardDuty.

Questions people ask
Is this CLF-C02 practice exam free?
Yes. All 199 questions, the timed mock exam and the explanations are free, and there's no account to create.
Are these real exam questions?
No. Real exam questions are confidential under the AWS candidate agreement. These are practice questions written to cover the same domains in the same scenario style, each with an explanation of why the answer is right.
How is the CLF-C02 mock exam scored?
Questions are drawn from every domain in proportion to the exam guide, and you get a raw percentage with a breakdown by domain. AWS uses scaled scoring, so treat 75% or more here as a sign you're ready rather than a predicted score.
