Locked In: Cloud Practitioner
CLF-C02 AWS Cert Exam Prep
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Know what each service is for and where the shared responsibility line sits. 70 lessons, 175 questions with worked explanations, 105 flashcards, offline.
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 exam asks what each AWS service is for and where the line sits between what AWS runs and what you run.
ORGANIZED BY THE PUBLISHED DOMAINS
35 study topics sit under the four published domains in the published proportions: Cloud Concepts 24 percent, Security and Compliance 30 percent, Cloud Technology and Services 34 percent, Billing, Pricing and Support 12 percent. The topics are this app's own breakdown of the four domains, written independently of the task statements in the exam guide. Each topic carries two lessons, 70 in all: one teaches the idea and one applies it. Alongside them sit 105 flashcards, a 70-term glossary, and 16 interactive scenario activities, four per domain, that sort, sequence and match.
CHECKED AGAINST THE CURRENT EXAM GUIDE
The content follows the CLF-C02 exam guide as checked on 15 October 2026. Support plans are taught as AWS now sells them: Basic, Business Support+, Enterprise and Unified Operations.
HOW THE QUESTIONS ARE WRITTEN
175 original practice questions, each with a worked explanation that says why the key is right and why each wrong answer is wrong. Most marks on a foundational exam are lost between two services that sound alike, so every topic carries a question that puts look-alike services side by side. Scenario questions offer only wrong answers written for that scenario, and the explanation gives the reason each one fails.
ANSWER ORDER AND ANSWER LENGTH
Each question's options are dealt into a stable order derived from the question itself, so the correct answer has no favorite position. A test in the project scores the bank on answer position, option length, punctuation, wording shared with the question, and how often each option appears, and fails the project's tests if any of those rules finds the answer in more than 45 percent of the bank, against 25 percent for a guess.
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 to 1,000 scale. The certification is valid for three years. AWS retires the Italian and German versions of the exam after 31 December 2026; the other languages continue.
WHAT IS FREE
12 lessons, 12 questions and 12 flashcards spread across the four domains, one scenario activity in each domain, and the 8 glossary definitions that match the free flashcards. Every glossary term is listed. 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 70 glossary definitions, all 16 scenario activities and the timed practice form. It is a single non-consumable purchase with nothing to renew. Restore Purchases sits on the purchase screen and in Settings.
PRIVACY

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
This update brings the app in line with the CLF-C02 exam guide as AWS publishes it in October 2026.
- Support plans match what AWS sells today: Basic, Business Support+, Enterprise and Unified Operations. Developer, Business and Enterprise On-Ramp end on 1 January 2027.
- Bulk data transfer is taught through link-rate arithmetic and AWS Direct Connect, because AWS Snowball is closed to new customers.
- Migration lessons cover all seven strategies, including relocate.
- Scenario, rule and measure questions offer only wrong answers written for that scenario, and each explanation gives the reason every wrong answer fails.
- Ordering activities accept any order the steps' dependencies allow.
- A new Well-Architected pillars activity replaces a Domain 1 activity that repeated Domain 4.
- Glossary definitions that repeat a paid flashcard now sit behind the unlock. Without it, 8 of the 70 definitions stay free; every term stays listed.
- Corrections to Free Tier, AWS Budgets, Secrets Manager rotation, Trusted Advisor, IAM Identity Center and shared responsibility details.
- Review history for the questions and flashcards rewritten in this update starts fresh, and a timed practice run saved in an earlier version cannot be resumed. Bookmarks and notes stay.
