SAA-C03 Design High-Performing Architectures Practice Question
A high-volume telemetry pipeline writes streaming click events that must be processed by multiple independent consumers. Which service is most appropriate?
⚠ Common exam trap
Candidates often confuse Kinesis Data Streams with simpler messaging services like SQS or SNS, but the key differentiator is that Kinesis supports multiple independent consumers processing the same stream in real-time with replay capability, whereas SQS is designed for point-to-point message delivery and SNS for pub/sub with push-based fan-out.

Correct answer & explanation
✓
Amazon Kinesis Data Streams
Amazon Kinesis Data Streams is the most appropriate service because it is designed for real-time streaming data ingestion and processing. It can capture and store terabytes of data per hour from hundreds of thousands of sources, such as click events, and allows multiple independent consumers to read and process the same stream concurrently using the Kinesis Client Library (KCL) or enhanced fan-out with dedicated throughput.
