A workload that needs to process bursty incoming events with retries and dead-letter handling is best paired with which AWS combination?
AAmazon RDS for MySQL queried by EC2 web servers
BAmazon Route 53 records updated by CloudFormation only
CAmazon SQS (with a dead-letter queue) consumed by AWS Lambda functions
DAmazon S3 Standard buckets accessed by EBS volumes
Answer & Solution
Correct answer: C. Amazon SQS (with a dead-letter queue) consumed by AWS Lambda functions
SQS + Lambda is the textbook event-driven decoupled pattern: SQS holds the surge, Lambda scales out consumers, the DLQ traps un-processable messages. The other combinations don't address event surges.
