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? The design must avoid adding custom operational scripts.
⚠ Common exam trap
A common mix-up: candidates confuse AWS DataSync or EBS as viable for streaming data, but DataSync is for batch file transfers and EBS is for block storage, neither supporting real-time, multi-consumer event processing.

Correct answer & explanation
✓
Amazon Kinesis Data Streams
Amazon Kinesis Data Streams is designed for real-time streaming of high-volume data, such as click events, and allows multiple independent consumers to process the same stream concurrently via enhanced fan-out or shared throughput. It provides durable, ordered data retention and integrates with AWS Lambda, Kinesis Data Analytics, and Kinesis Data Firehose without requiring custom operational scripts.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Amazon Kinesis Data Streams
Why this is correct
Amazon Kinesis Data Streams is a massively scalable, real-time data streaming service designed for high-throughput ingestion of click events and telemetry. Data is written to shards as durable records, allowing multiple consumer applications (e.g., via the Kinesis Client Library, Lambda, or enhanced fan-out) to read and process the same stream independently. It also supports replay and configurable retention up to 365 days, making it ideal for pipeline architectures with multiple downstream consumers.
- ✗
AWS DataSync
Why it's wrong here
AWS DataSync is a data transfer service meant for moving large volumes of files or object data between on-premises storage and AWS, or between AWS storage services, using agents and scheduled tasks. It is batch-oriented and requires a persistent source/destination endpoint, not a live event API that producers can write to in real time. Therefore it cannot ingest streaming click events or provide low-latency multi-consumer access to individual records.
- ✗
Amazon EBS
Why it's wrong here
Amazon EBS provides raw block-level storage volumes attached to EC2 instances, typically for use as file systems or databases. While EBS Multi-Attach allows a volume to be attached to multiple EC2 instances, it does not offer a streaming ingestion interface, record ordering, or retention controls for event data. It is a storage primitive, not a managed event-streaming service with producer/consumer semantics or via APIs for telemetry pipelines.
- ✗
Amazon Route 53
Why it's wrong here
Amazon Route 53 is a scalable DNS (Domain Name System) web service that resolves domain names to IP addresses, routes traffic across AWS resources, and supports health checks and traffic flow policies. It has no capability to ingest, store, or process event payloads like clickstream telemetry; its role is limited to query resolution and routing in the network path, not publish/subscribe or stream processing. Thus it cannot serve as a target for streaming events or as a medium for consumer applications to read records.
