DEA-C01 Data Ingestion and Transformation Practice Question
This DEA-C01 practice question tests your understanding of data ingestion and transformation. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 needs to ingest data from an Amazon S3 bucket into Amazon Redshift for analytics. The data is in CSV format and the Redshift table already exists. Which service can be used to perform this ingestion with minimal configuration?
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 Redshift COPY command
The Amazon Redshift COPY command is the most direct and minimal-configuration method to load data from an S3 bucket into an existing Redshift table. It is purpose-built for bulk data ingestion from S3, supports CSV format natively, and requires only the table name, S3 path, IAM role, and format options — no additional services or pipelines needed.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

AWS Database Migration Service (DMS)
Why it's wrong here
DMS is for migrating databases, not loading files into Redshift.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often overthink and choose AWS Glue or Kinesis Firehose because they assume a managed service is always required, but the COPY command is the simplest and most efficient native tool for batch loading from S3 into an existing Redshift table.
Trap categories for this question
Command / output trap
Glue is a full ETL service, but the COPY command is simpler for this task.
Detailed technical explanation
How to think about this question
The COPY command leverages Redshift’s massively parallel processing (MPP) architecture by automatically distributing the load across all compute nodes, reading from S3 in parallel using multiple slices. It supports advanced options like MANIFEST files for multi-file loads, REGION to avoid cross-region data transfer costs, and the ability to transform data on the fly using JSONPaths or CSV quoting rules. A real-world scenario is loading daily sales logs from S3 into a fact table, where COPY can handle millions of rows in minutes with minimal overhead.
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 |
