Interactive Diagrams

Architecture That Teaches, Not Just Tests

Every scenario centres on a real-world architecture diagram built to provider standards — AWS, Azure, GCP, and OCI conventions. See how services connect, why each component is chosen, and what trade-offs the architect made.

Step through the diagram one component at a time, or see the full picture at once. Each component has an explanation panel that links back to the exam objective it tests.

The Learning Flow

Five Steps from Problem to Mastery

Every scenario takes you through the same proven loop — business context, architecture, assessment, feedback, and reinforcement.

1

Read the Business Problem

Each scenario starts with a real business context: a company, a problem, and a set of constraints. You're the architect choosing the solution.

2

Study the Architecture

A provider-standard diagram shows how the solution is built. Click any service for details, or step through the diagram component by component.

3

Answer the Exam Question

A scenario-based question in real exam format. Four options, one correct. No tricks — just the kind of reasoning the exam actually tests.

4

Get Instant Feedback

Immediate explanation for every answer — why the correct option is right, and why each distractor is wrong. Linked directly to the exam objective.

5

Watch the Video Walkthrough

If you got it wrong — or want to see the full picture — a narrated video builds the architecture from scratch and explains every decision.
