AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

Configuring an SQS dead-letter queue (DLQ) on the EventBridge rule causes every event that cannot be delivered to the target to be pushed to the queue together with metadata that explains the failure. The team can review the exact payloads, remediate the issue, and replay the messages from the queue to the event bus or directly to the Lambda function. Enabling an archive captures all events on the bus, not just the failed ones, and costs more storage and replay time. CloudTrail data events log the API calls, not the event bodies, so they do not help with payload inspection or replay. Disabling retries sends errors back to the caller but still provides no mechanism to store or replay failed events.
