CLF-C02 is the exam code for the AWS Certified Cloud Practitioner certification — AWS's foundational credential covering cloud concepts, security, core services, and billing.
The AWS Certified Cloud Practitioner (CLF-C02) is AWS's entry-level, role-agnostic credential validating a high-level understanding of cloud concepts, core services, security, and billing. It's the starting point of the AWS certification path and requires no prior hands-on experience, though AWS recommends roughly six months of general exposure to AWS Cloud before sitting for it.
Ready for the next step? Most candidates move on to the AWS Certified Solutions Architect – Associate (SAA-C03) after passing CLF-C02.

The passing score is 700 on a scaled range of 100 to 1,000, calculated across the exam as a whole rather than per domain — a compensatory model, so weakness in one domain can be offset by strength in another. You won't know which questions were among the 15 unscored ones, so every question should be treated as if it counts.
Knowing the domains and passing score tells you what to study. The harder part most candidates underestimate is knowing how ready they actually are before exam day — and the most reliable way to find that out is testing yourself under real conditions rather than just re-reading notes.
Work through AWS's own Cloud Practitioner Essentials course and the official exam guide PDF. Prioritize the Shared Responsibility Model, IAM basics, and core compute/storage distinctions — these carry the most weight across the two largest domains.
Working domain by domain — Security and Compliance first, then Cloud Technology, then Cloud Concepts, then Billing — with scenario-based questions mirrors the actual reasoning style of the exam far better than flashcards alone. Our practice questions are organized this same way, so you can target weak domains directly instead of grinding through everything evenly.
Identify any domain where you scored below 70% and go deep specifically there rather than restudying everything evenly.
Run a complete 65-question, 90-minute mock under real conditions — no pausing, no looking anything up. Aim for 85% or above before booking the real exam.
