AWS Certified Data Engineer - Associate DEA-C01 — Topic 1 Question 281

Question

A data engineer needs a fully automated solution to check for new data in multiple databases and process data that the solution finds. The solution must run every hour. The solution must be compatible with Amazon RDS, Amazon DynamoDB, and Amazon OpenSearch Service. The solution must be able to process up to 10 MB of data at one time. The solution must be optimized for costs and operational overhead. The solution must have robust error handling capabilities. Which solution will meet these requirements?

Accepted Answer

Correct answer: B. The correct answer is B. Option B: Use Amazon EventBridge to invoke an AWS Lambda function every hour to check for data. Configure the function to send a message to an Amazon Simple Queue Service (Amazon SQS) queue when the function finds new data. Use... AWS Lambda runs code without provisioning servers and scales automatically, which minimizes operational overhead. Amazon SQS is a fully managed message queue that decouples components and absorbs traffic spikes. Amazon EventBridge routes events between services with rules, enabling event-driven, decoupled architectures.
