A company is building a serverless application that processes large volumes of data from a mobile app. A Lambda function processes the data and stores it in DynamoDB. The company must ensure the application can recover from failures and continue processing without losing records.

Which solution will meet these requirements?

A.

Configure the Lambda function with a dead-letter queue (DLQ) using SQS. Retry failed records from the DLQ with exponential backoff.

B.

Configure the Lambda function to read records from Amazon Data Firehose. Replay Firehose records in case of failures.

C.

Use Amazon OpenSearch Service to store failed records. Configure Lambda to retry failed records from OpenSearch. Use EventBridge for orchestration.

D.

Use Amazon SNS to store failed records. Configure Lambda to retry records from SNS. Use API Gateway to orchestrate retries.
