Fault Tolerance — AWS Solutions Architect Associate Practice Questions
Fault tolerance in AWS architecture refers to a system's ability to continue operating correctly even when one or more components fail, typically by eliminating single points of failure through redundancy. The Solutions Architect Associate exam heavily tests fault-tolerant design patterns, including deploying across multiple Availability Zones, using Auto Scaling groups, and configuring load balancers to route traffic away from unhealthy instances. Candidates must understand the difference between fault tolerance (zero downtime) and high availability (minimal downtime), as the exam uses both terms precisely. Services like Amazon RDS Multi-AZ, S3 cross-region replication, and ELB are commonly featured in fault-tolerance scenario questions.
