DEA-C01 Data Ingestion and Transformation Practice Question
A company wants to ingest streaming data from thousands of IoT devices into AWS for real-time analytics. Which AWS service is best suited for this purpose?
⚠ Common exam trap
A common mix-up: candidates confuse batch-oriented services like S3 or compute services like Lambda with the dedicated streaming ingestion layer required for real-time data, overlooking that Kinesis Data Streams provides the necessary buffering, ordering, and replay capabilities.

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 Streams
Amazon Kinesis Data Streams is purpose-built for ingesting and processing streaming data at scale from thousands of sources. It can capture and store terabytes of data per hour from IoT devices, enabling real-time analytics with millisecond latencies. The service provides durable, ordered data streams that can be consumed by multiple applications simultaneously.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Amazon S3
Why it's wrong here
Amazon S3 is an object storage service, not a real-time ingestion engine; it lacks the low-latency, continuous data capture and stream processing capabilities required for thousands of IoT devices. It is tempting because S3 is often used as a durable landing zone for batch data or as a destination for processed streaming data, and would be correct if the scenario required storing the ingested data after a streaming service like Amazon Kinesis had handled the real-time ingestion and analytics.
- ✗
AWS Lambda
Why it's wrong here
Lambda processes data but is not a primary ingestion service.
- ✗
Amazon RDS
Why it's wrong here
RDS is a relational database, not for streaming ingestion.
- ✓
Amazon Kinesis Data Streams
Why this is correct
It is designed for real-time streaming data ingestion.
