AWS Solutions Architect (SAA-C03) pattern recognition

The structural question types SAA-C03 reuses

Beneath surface variation in scenario details, SAA-C03 draws on a recurring set of architecture decision frameworks that appear throughout the exam. Private connectivity decisions follow a consistent scope hierarchy across VPC endpoints, peering, and Direct Connect. Database scaling scenarios tend to reuse the same tension between read replicas, ElastiCache, and DAX with only the access pattern shifted. Disaster recovery questions often reduce to arithmetic: which tier satisfies both the stated RPO and RTO without over-provisioning. Event-driven decoupling questions differentiate SQS, SNS, EventBridge, and Kinesis by delivery guarantee and consumer model, and they do so in ways that make service confusion expensive. Recognizing which framework a question is invoking, before reading the answer choices, is the skill this section trains.
