Below are 15 original AWS Cloud Practitioner (CLF-C02) practice questions, mapped to the official exam domains. Every question has the answer, why it is right, and why each other option is wrong. Answer each one before you read the explanation, and write down the domain of every question you miss. That list is more useful than your score.
How these questions map to the exam
The questions follow the official CLF-C02 domain weights, so the heavier domains get more questions.
| Domain | Official weight | Questions here |
|---|---|---|
| 1. Cloud Concepts | 24% | 4 (Q1–Q4) |
| 2. Security and Compliance | 30% | 4 (Q5–Q8) |
| 3. Cloud Technology and Services | 34% | 5 (Q9–Q13) |
| 4. Billing, Pricing, and Support | 12% | 2 (Q14–Q15) |
The real exam has 65 questions in 90 minutes: 50 scored and 15 unscored. Questions are multiple choice (one correct answer) or multiple response (two or more correct answers from five or more options). For a deeper look at each domain, see the CLF-C02 domain breakdown.
The questions
Question 1 · Cloud Concepts
An online retailer buys enough on-premises servers to handle its Black Friday peak. For the rest of the year most of those servers sit idle. When a marketing campaign goes viral unexpectedly, the servers still run out of capacity. Which advantage of cloud computing addresses this problem most directly?
Answer: C
The retailer's problem is capacity planning: it over-provisions for the peak and still under-provisions for surprises. In the cloud you scale up and down with actual demand, so you stop guessing capacity.
- A is wrong because the problem is not about reaching users in new geographic Regions.
- B is wrong because economies of scale explain why AWS prices are low, not how you match capacity to demand.
- D is wrong because it is about removing data centre operations work, not about sizing capacity.
How did you do?
Fifteen questions are a sample, not a readiness verdict. The real exam has 50 scored questions across four domains, and a single unlucky question moves your score here by almost 7%. Use these bands as a first signal only.
| Correct | What it suggests |
|---|---|
| 13–15 | A strong start. Confirm it with a full-length practice exam before you book. |
| 10–12 | Close, with gaps. Your misses probably cluster in one or two domains. |
| 7–9 | Solid basics, but not exam-ready yet. Study your weakest domain first. |
| 0–6 | Start with the fundamentals, domain by domain, then come back and retest. |
Whatever your score, look at the domains you wrote down. Your weakest domain is where your next study hour should go. Readiness means steady results in every domain across many questions, not one good run of 15. If you want a structured review, the CLF-C02 cheat sheet covers the core services by domain, and Am I ready for AWS Cloud Practitioner? explains how to judge readiness.
