Study Azure AZ-900 Architecture and Services: key concepts, common traps, and exam decision cues.
This is the biggest AZ-900 chapter because Microsoft wants you to recognize the major Azure building blocks and service families. The exam still stays conceptual. It is testing whether you know which layer a service belongs to, what job it is meant to solve, and which terms are hierarchy terms rather than products.
Microsoft currently weights Azure architecture and services at 35-40% of the exam.
