SAP-C02 Design for New Solutions Practice Question
A company is designing a data lake solution on Amazon S3. Data is ingested from multiple sources and stored in a raw bucket. The data must be processed and transformed before being moved to a curated bucket. The processing logic is complex and includes conditional transformations. Which service should be used to orchestrate the transformation pipeline?
⚠ Common exam trap
Candidates often confuse AWS Glue ETL jobs as an orchestration tool because it can transform data, but Glue is a processing engine, not a workflow orchestrator; Step Functions is the correct service for coordinating complex, conditional pipelines.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Step Functions
AWS Step Functions is the correct choice because it is designed to orchestrate complex, multi-step workflows with conditional branching, retries, and error handling. It can coordinate AWS Lambda functions, AWS Glue jobs, and other services to process and transform data from a raw S3 bucket to a curated bucket, making it ideal for a transformation pipeline with complex logic.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS Data Pipeline
Why it's wrong here
Data Pipeline is legacy and less flexible than Step Functions.
- ✓
AWS Step Functions
Why this is correct
Step Functions can orchestrate complex workflows with conditional branching.
- ✗
AWS Lambda functions
Why it's wrong here
Lambda is for individual functions; orchestration would require custom code.
- ✗
AWS Glue ETL jobs
Why it's wrong here
Glue ETL is for data transformation, not orchestration of multi-step pipelines.

| 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 |
