DEA-C01 Data Ingestion and Transformation Practice Question
A data engineer is designing a data ingestion pipeline for real-time clickstream data. The data must be available for both real-time analytics and batch processing. The engineer wants to use Amazon Kinesis Data Streams. Which THREE components should be included in the architecture?
⚠ Common exam trap
Many exam-takers assume Kinesis Data Analytics is a required component for real-time analytics, but the question only requires the data to be available for real-time analytics—not that analytics must be performed within the pipeline—so Kinesis Data Analytics is optional, not mandatory.

Correct answer & explanation
✓
Amazon Kinesis Data Streams
Amazon Kinesis Data Streams is the core ingestion service for real-time clickstream data, providing low-latency, durable storage of data records that can be consumed by multiple applications simultaneously. It enables both real-time analytics (via Kinesis Data Analytics or KCL applications) and batch processing (by integrating with Kinesis Data Firehose to deliver data to Amazon S3).
