An independent study companion for the AWS Certified Cloud Practitioner exam, exam code CLF-C02, written for people taking their first cloud certification. Salespeople, finance staff, project managers and engineers all sit this one. The value is knowing what each service is for and where the line sits between what AWS runs and what you run. COVERS THE PUBLISHED OUTLINE 35 topics map one to one onto the published exam outline, distributed in the published domain proportions: Cloud Concepts 24 percent, Security and Compliance 30 percent, Cloud Technology and Services 34 percent, Billing, Pricing and Support 12 percent. Each topic carries two lessons, 70 in all, one that teaches the idea and one that applies it. Alongside them sit 105 flashcards, 70 glossary entries, and 16 interactive scenario activities, four per domain, that sort, sequence and match. HOW THE QUESTIONS ARE WRITTEN 175 original practice questions, each with a worked explanation that says why the key is right and why the tempting wrong answer is wrong. On a foundational exam most marks are lost between two services that sound alike, so every explanation is written to teach the distinction rather than to confirm the answer. ANSWER ORDER AND ANSWER LENGTH A bank that lists the correct answer first and never moves it turns position into a shortcut. Here each question's options are dealt into a stable order derived from the question itself, the same order every time you see it, rather than left where they were typed. The few sets whose order carries meaning, such as ascending numbers, stay as written. The bank measures itself for the position tell and for the longest answer is correct tell, and holds both near chance. PRACTICE AND REVIEW A timed practice form of 40 questions in 55 minutes, drawn in the published domain proportions. Spaced repetition resurfaces what you got wrong. Progress by domain, bookmarks and search across the whole catalog. The exam itself is 65 questions in 90 minutes, 50 of them scored and 15 unscored, passing at 700 on a 100-1000 scale. The certification is valid for three years. WHAT IS FREE 12 lessons, 12 questions and 12 flashcards, spread across the four domains, plus one scenario activity in each domain. The sampler is fixed, so it shows the real shape of the material rather than a slice of one domain. No account, no sign-up, no time limit. WHAT THE UNLOCK ADDS One payment opens the rest: all 70 lessons, all 175 questions, all 105 flashcards, all 16 scenario activities and the timed practice form. It is a single non-consumable purchase, not a subscription, and nothing renews. Restore Purchases sits on the purchase screen and in Settings. PRIVACY Everything runs on the device and offline. No account, no network needed, no ads, no analytics, no tracking, no data collection of any kind. Progress stays on your device. INDEPENDENCE This is an independent study aid.
