Free Udemy Course 2025: AZ-900 Regions and Availability Zones: 1500 Questions

This is a complete practice test collection designed to help you master one of the most essential Azure Fundamentals topics — global infrastructure, regions, and availability zones. With 1,500 carefully developed questions divided into six detailed exam sections, this course offers a structured and realistic way to prepare for the Microsoft Certified: Azure Fundamentals (AZ-900) certification exam.You will explore in depth how Microsoft Azure structures its global network of data centers, how regions and availability zones provide reliability, and how redundancy is built to ensure high availability and fault tolerance. Each section contains 250 unique questions aligned with real-world exam content to help you understand Azure’s infrastructure from both a conceptual and practical perspective.The course is divided into six comprehensive sections, each focusing on a key aspect of Azure’s global design:1. Understanding Azure Regions and Geography (250 Questions)This section covers how Azure organizes its cloud infrastructure across multiple regions and geographies. You’ll learn about regional boundaries, data residency, compliance requirements, and how Microsoft structures its global footprint to meet performance, scalability, and legal obligations.2. Availability Zones and High Availability (250 Questions)Here you’ll study how Azure achieves fault tolerance and uptime through Availability Zones. Topics include redundancy, fault domains, update domains, SLA concepts, and the difference between availability sets and zones, helping you design resilient cloud solutions.3. Azure Data Centers and Infrastructure Design (250 Questions)This section explores the physical and technical design of Microsoft’s data centers. You’ll gain insight into power, cooling, and network architecture, as well as global backbone connectivity, security layers, compliance mechanisms, and environmental sustainability practices.4. Redundancy, Disaster Recovery, and Fault Tolerance (250 Questions)Focused on resilience and recovery, this part teaches you how Azure handles unexpected failures. You’ll study replication types, backup strategies, geo-redundancy, RPO and RTO concepts, and how to design services that continue to operate during outages and disasters.5. Service Deployment, Compliance, and Regional Availability (250 Questions)This section helps you understand how Azure deploys services across regions and maintains compliance with international standards. You’ll learn about region-specific feature rollouts, resource deployment strategies, legal data boundaries, and key frameworks such as ISO, SOC, and GDPR.6. Designing Global Solutions and Best Practices (250 Questions)The final section focuses on architecture, scalability, and global solution design. You’ll apply the principles learned in earlier sections to create multi-region, hybrid, and resilient solutions while optimizing cost, performance, and reliability.Each question includes detailed explanations to help you not only identify the correct answer but also understand the reasoning behind it. This transforms each test into an active learning experience rather than simple memorization.Whether you are preparing for your first Microsoft certification or seeking to strengthen your foundational Azure knowledge, this practice test collection provides everything you need for comprehensive exam readiness and a deep understanding of Azure’s regional and global infrastructure.
