Question 45 of 1,711
DEA-C01 Data Ingestion and Transformation Practice Question
A data engineer needs to ingest data from a SaaS application that sends webhooks in JSON format. The data must be stored in S3 for batch analysis. Which AWS services can receive the webhooks and store the data in S3 with minimal custom code? (Choose TWO.)
⚠ Common exam trap
Many candidates assume Lambda is the only serverless option for webhook ingestion, overlooking API Gateway's direct S3 integration, or they mistakenly think Kinesis Data Streams can directly receive HTTP requests without a custom producer.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon API Gateway with S3 integration
Amazon API Gateway with S3 integration (Option D) allows you to create a REST API that directly writes incoming webhook payloads to an S3 bucket without any custom code, using a proxy integration with an AWS service. This minimizes custom code because the integration handles the mapping and storage automatically.
