AZ-900 Microsoft Azure Fundamentals

Master Azure Fundamentals by learning how Microsoft expects you to think—not what to memorize. The AZ-900 exam is not about building Azure solutions. It is about recognizing cloud concepts, classifying Azure services, and selecting the correct answer from several plausible options. This book introduces The Decision-Making Method, a practical framework designed to help you analyze every question through constraints instead of memorization. Inside this book you'll learn: • Cloud concepts and the Shared Responsibility Model • Public, Private and Hybrid Cloud • IaaS, PaaS and SaaS • Azure global infrastructure • Compute, networking and storage services • Azure identity and security • Governance, management and monitoring • Decision tables that simplify complex topics • Exam strategies and common traps • Full-length practice exam with 45 realistic questions Unlike traditional certification books, this guide teaches you how to think through Azure questions, making it useful not only for passing AZ-900 but also for building a solid cloud foundation. Updated for the latest Microsoft certification objectives, this guide covers the Skills measured as of July 2026 and follows the official exam domains. Part of the Azure Certification Decision Guides series Learn Microsoft certifications through decision-making rather than memorization. Every guide follows the same proven methodology, using decision tables, comparison frameworks, architectural thinking, and realistic practice questions to help you understand why an answer is correct—not simply what to memorize.
