DEA-C01 Data Ingestion and Transformation Practice Question
A data engineer is designing a data lake on Amazon S3. The data ingestion pipeline must handle both batch and streaming data. The engineer wants to use a single service to ingest both types of data. Which service should the engineer choose?
⚠ Common exam trap
A common mix-up: candidates confuse Amazon Kinesis Data Firehose with Amazon Kinesis Data Streams, but the question specifically asks for a single service that handles both batch and streaming data and delivers to S3, which Firehose does directly without requiring a separate consumer.
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 Kinesis Data Firehose
Amazon Kinesis Data Firehose is the correct choice because it is a fully managed service that can ingest both batch and streaming data and deliver it directly to Amazon S3 without requiring custom code. It can receive streaming data from sources like Kinesis Data Streams or Amazon CloudWatch Logs, and also handle batch data via API calls, making it a single ingestion point for both patterns. While AWS Glue does support both batch and streaming ETL, it is primarily an ETL service that requires writing and managing jobs, and is not designed as a direct data ingestion service to S3 without additional configuration. Therefore, Kinesis Data Firehose is the most appropriate service for this requirement.

- ✗
Amazon Athena
Why it's wrong here
Athena is a query service.
- ✓
Amazon Kinesis Data Firehose
Why this is correct
Firehose can ingest streaming data and deliver to S3 in near real-time; batch data can be sent via Firehose API.
- ✗
S3 Transfer Acceleration
Why it's wrong here
Transfer Acceleration only speeds up uploads.
- ✗
AWS Glue
Why it's wrong here
Glue is batch-only.
