An interactive, browser-based study guide for the Microsoft AZ-400: Designing and Implementing Microsoft DevOps Solutions certification exam.

🌐 Live Demo: leonmc00.github.io/az400-study-hub/az400-study-hub-v2.html

This project was built as a hands-on alternative to reading through walls of text. It covers all five AZ-400 exam domains with a mix of interactive activities designed to reinforce learning through doing rather than just reading.

Built with plain HTML, CSS, and vanilla JavaScript — no frameworks, no dependencies, no build steps. Open the file in any browser and it works.

All five exam domains with expandable cards covering theory, key topics, and tools — each with hands-on activities built in.

Click-to-flip flashcards covering must-know definitions for each domain. Covers DORA metrics, branching strategies, security scanning types, SRE terminology, and more.

Match terms to definitions, strategies to use cases, and tools to scenarios. Immediate visual feedback — correct drops turn green, wrong drops shake and return.

Build a real Azure Pipelines YAML file block by block. Each block added reveals a tip explaining what it does and why it matters in a real pipeline.

A four-step guided scenario where you make decisions to build a production-ready CI/CD pipeline. Steps unlock sequentially with full explanations for correct and incorrect answers.

Eight exam-style scenario questions covering all domains. Each question includes context, four answer options, and a detailed explanation of why the correct answer is right — and why the others are wrong.

Visual quick-reference cards covering branching strategies, deployment patterns, DORA metrics, secrets management, IaC options, and security scanning types side by side.

Study timeline, exam logistics, what to prioritise, and common exam traps — including the things the AZ-400 exam consistently tests.
