Availability Zones — AWS Solutions Architect Associate Practice Questions
Availability Zones are physically separated data centers within an AWS Region, each with independent power, networking, and cooling, enabling fault isolation at the infrastructure level. The exam emphasizes deploying resources across multiple AZs to achieve high availability and protect against single-point failures without cross-region latency or cost. Key services such as ELB, RDS Multi-AZ, and Auto Scaling groups are designed to distribute workloads across AZs automatically. Understanding which services are AZ-scoped versus Region-scoped is critical for answering architecture resilience questions correctly.
