SAP-C02 is a decision-making exam, not a service exam. Here are the patterns that dominate the question bank.
1. Multi-account landing zone
Know when Control Tower is correct vs when you build it yourself. Cost boundaries and blast-radius choices drive this.
2. Event-driven at scale
EventBridge vs SNS+SQS vs Kinesis. Know their delivery, ordering, and replay semantics cold.
3. Private networking
Transit Gateway + PrivateLink + Direct Connect patterns. Focus on the cost and blast-radius differences.
