About CloudCertPrep

CloudCertPrep is built and maintained by Alex Santonastaso, and the entire codebase and question bank are public on GitHub.

Who maintains it

CloudCertPrep is created and maintained by Alex Santonastaso, a software engineer who built the platform to prepare for the AWS Cloud Practitioner exam, then passed it (verified Credly badge). The goal is simple: a high-quality, genuinely free study tool that anyone can use, inspect, and improve, without the ads, upsells, and dubious "exam dumps" that clutter the rest of the space.

How the question banks are built

Every question is aligned to the official AWS exam guide and its task statements, so the topic coverage and difficulty mirror what you will actually face on exam day. Each question ships with a detailed explanation of why the correct answer is right and why each distractor is wrong. The explanations are where the real learning happens.

Questions are validated by an automated schema checker before they are merged, and the whole bank is publicly auditable on GitHub. Anyone can read a question, cross-reference it against the AWS documentation, report an error, or open a pull request with a correction. Community contributions are reviewed against the validator and the exam guide before they go live.

Question and Explanation Methodology

Building on how the banks are assembled above, this is the editorial standard every question is held to before it ships.

How questions are written

Each question is authored against a specific task statement in the official AWS exam guide, so coverage and difficulty track the scored exam rather than drifting into trivia. New questions arrive as community contributions through a GitHub pull request, where anyone can propose, discuss, and refine them in the open. Questions are never sourced from braindumps or exam dumps. Reproducing real exam content breaches the AWS certification agreement and teaches recall instead of understanding, so we write original questions from the published exam guide and documentation.

How explanations are structured

Every explanation has two parts: a rationale for the correct answer that explains why it is right, and a per-distractor rationale that explains why each incorrect option is wrong. Reading why the wrong answers are wrong is what turns a practice question into genuine understanding you can carry into the exam.

How the banks are reviewed

Changes are reviewed through GitHub pull requests before merging, so every edit has a visible author and review trail. The entire bank is publicly auditable: each question links to its source file by permalink on GitHub, so you can verify any claim against the AWS documentation yourself. Everything is MIT licensed, free to read, reuse, and improve.

Why it is free and open source

CloudCertPrep is MIT licensed with no ads, no paywalls, and no premium tier. Good exam prep should not be locked behind a subscription. The project is sustained by optional Ko-fi donations, which help keep hosting paid for while the platform itself stays free and ad-free.
