DEA-C01 Data Ingestion and Transformation Practice Question
A data engineer is designing a streaming ingestion pipeline using Amazon Kinesis Data Streams with multiple consumers. The data must be processed by a Lambda function for real-time alerts and also stored in Amazon S3 for historical analysis. Which THREE components are needed to implement this architecture? (Choose THREE.)
⚠ Common exam trap
Many candidates confuse Amazon Kinesis Data Analytics as a necessary component for any streaming pipeline, but it is only required when you need to perform real-time analytics on the stream, not for simple data movement to S3.
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 Firehose
Amazon Kinesis Data Firehose is the correct component because it is the fully managed service designed to load streaming data into Amazon S3 without requiring custom code. It can directly subscribe to a Kinesis Data Stream as its source and automatically buffer, batch, compress, and deliver records to S3 for historical analysis, making it the ideal choice for the storage leg of this architecture.
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 Kinesis Data Firehose
Why this is correct
Reads from the stream and delivers to S3.
- ✓
Amazon Kinesis Data Streams
Why this is correct
Serves as the primary ingestion endpoint.
- ✓
AWS Lambda function
Why this is correct
Consumes from the stream for real-time processing.
- ✗
Amazon Kinesis Data Analytics
Why it's wrong here
Not required for simple fire-and-forget to S3.
- ✗
Amazon SQS queue
Why it's wrong here
Unnecessary; Lambda can directly read from Kinesis.
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 |
