SAP-C02 Design for New Solutions Practice Question
A company is designing a new application that will process streaming data from IoT devices. The data must be ingested in real-time and stored in Amazon S3 for long-term analytics. Which AWS service should be used to ingest the streaming data?
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 Streams
Amazon Kinesis Data Streams is designed for real-time data ingestion and can stream data directly to Amazon S3. Option A is wrong because SNS is a pub/sub messaging service, not intended for real-time data ingestion. Option B is wrong because SQS is a message queue service, not optimized for streaming ingestion. Option C is wrong because AWS DMS is used for database migration, not for ingesting streaming data.
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 Simple Notification Service (SNS)
Why it's wrong here
Amazon SNS is a pub/sub messaging service, not designed for real-time data ingestion from IoT devices.
- ✗
Amazon Simple Queue Service (SQS)
Why it's wrong here
SQS is a message queuing service for decoupling application components, not a real-time ingestion engine. It lacks the ability to directly stream data into Amazon S3 without a separate consumer process polling the queue and writing objects. This fails the stem’s requirement for immediate, continuous ingestion. SQS would be tempting if the need were to buffer messages between microservices or to smooth out variable processing loads, where asynchronous, pull-based delivery is acceptable.
- ✗
AWS Database Migration Service (DMS)
Why it's wrong here
AWS Database Migration Service (DMS) is used for migrating databases, not for ingesting streaming data.
- ✓
Amazon Kinesis Data Streams
Why this is correct
Amazon Kinesis Data Streams is purpose-built for real-time data streaming and can directly integrate with Amazon S3 for storage.
Quick reference
AWS S3 Storage Class Comparison
| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
