AWS SAP-C02 · Question 48 · Domain 2.4: Reliability
An enterprise architecture uses Amazon EventBridge to route events between dozens of microservices. The architect needs to ensure that events are not lost if a target service is temporarily unavailable, and they need a mechanism to replay past events to recover from application logic errors. How should EventBridge be configured?
Answer options:
Use Amazon SQS as the primary event bus instead of EventBridge.
Configure a Dead-Letter Queue (DLQ) for the targets and enable EventBridge Event Archives.
Enable AWS CloudTrail to record the events and use AWS Lambda to replay them.
Use AWS Step Functions to orchestrate the event delivery with exponential backoff.
