Quick Answer
The correct answers are Amazon API Gateway with Kinesis Data Firehose integration, because this combination directly receives webhook payloads and streams them into S3 with zero custom code—API Gateway acts as the HTTP endpoint for the SaaS webhook, while Firehose handles buffering, transformation, and delivery to S3 automatically. On the AWS Certified Data Engineer Associate DEA-C01 exam, this scenario tests your understanding of serverless ingestion patterns for batch analytics, specifically how to minimize custom code when bridging external webhooks to S3. A common trap is choosing Lambda alone, which requires you to write code to parse and upload to S3, or Kinesis Data Streams, which needs a custom producer to read from the stream. Remember the memory tip: “Firehose fires straight to S3, no code needed—API Gateway catches the webhook, Firehose delivers the hook.”
This DEA-C01 practice question tests your understanding of data ingestion and transformation. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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.)
AWS Lambda with S3 SDK
Why wrong: Requires custom code.
AWS Glue with a Python shell job
Why wrong: Glue is not designed for webhook ingestion.
Amazon Kinesis Data Streams
Why wrong: Requires a custom producer to put records.
Amazon API Gateway with S3 integration
API Gateway can directly write to S3.
Amazon API Gateway with Kinesis Data Firehose integration
API Gateway can receive webhooks and integrate with Firehose.
Answer choices
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
Option A and Option D are correct because API Gateway can receive webhooks and route to Firehose or S3. Option B is wrong because Glue cannot directly receive webhooks. Option C is wrong because Kinesis Data Streams requires custom producers. Option E is wrong because Lambda can receive but not directly store to S3 without code.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
