DEA-C01 Data Ingestion and Transformation Practice Question
This DEA-C01 practice question tests your understanding of data ingestion and transformation. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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?
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 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).
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often 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.
Detailed technical explanation
How to think about this question
Kinesis Data Streams uses shards to scale ingestion, with each shard supporting up to 1 MB/s or 1,000 records/s for writes. The KCL application uses DynamoDB for checkpointing and load balancing across shards, enabling exactly-once processing semantics. Kinesis Data Firehose can batch records from the stream and deliver them to S3 with configurable buffer sizes (e.g., 1 MB or 60 seconds), ensuring cost-effective batch storage without additional code.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
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 |
