6. ⚠️ SUPPLEMENTARY — Not on AZ-400 Exam (AZ-204 Content)

⚠️ Supplementary Content Notice: The topics in Phase 6 — API Management, Event Hubs, IoT Hub, and Service Bus — are not part of the AZ-400 exam scope. They belong to the AZ-204 (Azure Developer Associate) exam. The official AZ-400 domains (as of July 26, 2024) are: (1) Design and implement processes and communications, (2) Design and implement a source control strategy, (3) Design and implement build and release pipelines, (4) Develop a security and compliance plan, and (5) Implement an instrumentation strategy. This content is retained as optional background reading only. Do not prioritize this over Phases 2–5 during your AZ-400 exam preparation.

Welcome to Phase 6, where we delve into advanced integration patterns for Azure solutions. Building upon your understanding of Azure's core concepts, compute, storage, security, caching, logging, and monitoring from previous phases, this section focuses on the practical application of API management, event-driven architectures, and message-based communication.

This phase provides supplementary context that may help you understand integration scenarios referenced in pipeline and instrumentation questions. We'll explore architectural patterns and best practices that ensure your applications communicate securely, reliably, and scalably across distributed systems. The focus here is on comprehension and practical application, enabling you to build robust and interconnected solutions.
