DEA-C01 Data Ingestion and Transformation Practice Question
This DEA-C01 practice question tests your understanding of data ingestion and transformation. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 company needs to ingest data from multiple SaaS sources (e.g., Salesforce, Marketo) into Amazon S3 for analytics. Which AWS service is designed for this purpose?
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 AppFlow
Amazon AppFlow is a fully managed integration service specifically designed to securely transfer data between SaaS applications (like Salesforce, Marketo, Slack, and Zendesk) and AWS services such as Amazon S3 and Amazon Redshift. It supports scheduled, event-driven, or on-demand data ingestion with built-in transformations, filtering, and validation, making it the ideal choice for this use case.
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 confuse AWS Glue's ETL capabilities with native SaaS connectivity, but Glue requires custom connectors or AWS Glue Studio's visual ETL jobs to connect to SaaS sources, whereas AppFlow is purpose-built for this task.
Detailed technical explanation
How to think about this question
Under the hood, Amazon AppFlow uses OAuth 2.0 for authentication with SaaS providers and supports incremental data transfers via change data capture (CDC) mechanisms like Salesforce's GetUpdated/GetDeleted APIs. It can also handle data deduplication and partitioning, and it integrates with AWS PrivateLink for private connectivity, ensuring data never traverses the public internet. A real-world scenario is syncing Salesforce opportunities to S3 daily for a Tableau dashboard, where AppFlow automatically handles schema evolution and retries on failures.
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 |
