Practice Tests for AWS CLF

EC2, S3, IAM, VPC — you know the names, but can you explain the difference?
This app builds the knowledge you need to pass the AWS Certified Cloud Practitioner exam (CLF-C02), five questions at a time.
It was written by a developer who holds all 12 AWS certifications, scoped to the foundational level.

If you have ever bought a study guide and never finished it, start with the questions instead. Answer, read the explanation, repeat. That alone moves a term from "I've heard of it" to "I can explain it."

All you need is your phone. Study anytime, anywhere, in any spare moment — no need to set aside time at a desk.

■ The same structure as the real exam

The AWS Certified Cloud Practitioner exam draws from four domains, each with a fixed share of the scored questions. All 300 questions in this app follow the same weighting.

・Cloud Concepts (24% of the exam)
・Security and Compliance (30%)
・Cloud Technology and Services (34%)
・Billing, Pricing and Support (12%)

Your progress per domain becomes a picture of how you would score on the real thing. When you can see "Technology is at 80%, but Billing is untouched," you know exactly what to study the week before the exam.

■ Key features

【Five questions per set — finish one on your commute】
Each set is five questions. You don't need a free evening: one set fits into a train ride or a coffee break. Short sessions are what make a daily habit stick.

【Every question explained】
Right or wrong, you get the reasoning behind the answer. At the foundational level, most AWS questions come down to knowing what a service does and what a term means — so reading the explanations is the exam prep.

【Works offline, uses no data】
Every question ships inside the app. Study on the subway, in airplane mode, anywhere the signal drops. After the download, no connection is needed at all.

【Progress tracked question by question】
Each question you answer correctly is recorded individually. Whether you meet it in a domain set or in random practice, it counts once toward your progress — so the number you see is the number of questions you actually understand.

【Start anywhere you like】
No sets are locked. Work through them in order, or go straight to your weakest domain. You never have to clear one set to unlock the next.

【Random practice for exam conditions】
Random practice pulls from all four domains at once. Answering without knowing the domain in advance is closer to how the real exam feels — use it as a final check.

【Exam facts inside the app】
90 minutes, 65 questions, a passing score of 700 out of 1000 — the essentials are collected on one screen. Read it once when you decide to sit the exam.

【No sign-up, no account】
There is no registration and no login. Install it and answer your first question straight away.

【Available in 10 languages】
Questions and explanations in English, Japanese, German, Spanish, Portuguese, French, Italian, Korean and Chinese (Simplified and Traditional). If you want to get used to the English phrasing used on the exam, switch the language and study that way.
