AWS Certified Developer – Associate (DVA-C02) — Question 461
A company has an ecommerce application. The application's API sends order data to an Amazon Simple Queue Service (Amazon SOS) queue. A developer needs to modify the application to enrich the order data before the application sends the order data to a fulfillment system.
Which solution will meet this requirement with the LEAST development effort?
Answer options
- A. Create an AWS Lambda function to poll the SOS queue. enrich the message data, and send the enriched data to the fulfilment system, Create an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe the Lambda function to the SNS topic.
- B. Create an AWS Step Functions state machine. Configure an Amazon EventBridge rule to run the state machine when an order is published to the SQS queue. Map the orders to an AWS Lambda function. Program the Lambda function to perform the data enrichment and to invoke the state machine. Configure the last step of the state machine to send the enriched data to the fulfilment system,
- C. Create an Amazon EMR cluster to read messages from the SQS queue. Configure an EMR job to enrich the order data. Create and configure an Amazon S3 bucket as the output location. Adjust the order fulfilment system to retrieve the enriched files from the S3 bucket.
- D. Create an Amazon EventBridge pipe that uses event enrichment. Configure the SQS queue as a source for the pipe. Set the fulfillment system as the target of the pipe.
Correct answer: D
Explanation
Amazon EventBridge Pipes provides a direct, low-code integration to connect supported sources (like Amazon SQS) to targets while supporting intermediate enrichment steps, resulting in the least development effort. Other options, such as orchestrating Step Functions, setting up EMR clusters, or manually managing Lambda/SNS combinations, introduce unnecessary architectural complexity and higher operational overhead for a simple data enrichment pipeline.
