- A
Use the Amazon Redshift COPY command to load data directly from the on-premises storage.
Why wrong: COPY command requires data in a supported format in S3.
- B
Use AWS Glue to convert the proprietary format to Apache Parquet and load into Amazon Redshift.
AWS Glue can transform data into columnar formats optimized for Redshift.
- C
Use AWS Database Migration Service (DMS) to migrate the data directly to Redshift.
Why wrong: DMS is for database migrations, not for proprietary storage formats.
- D
Use Amazon Kinesis Data Firehose to stream the data to Redshift.
Why wrong: Kinesis is for streaming data, not batch migration.

SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
This SAP-C02 practice question tests your understanding of accelerate workload migration and modernization. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 is migrating a large-scale data warehouse from on-premises to Amazon Redshift. The current on-premises solution uses a proprietary columnar storage format. The company needs to minimize data transformation effort. Which approach should the company take?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"minimum / minimize"Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
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
✓
Use AWS Glue to convert the proprietary format to Apache Parquet and load into Amazon Redshift.
Option B is correct because AWS Glue can crawl the proprietary columnar storage format and convert it to Apache Parquet, a columnar format efficiently loaded into Amazon Redshift via COPY from S3, minimizing data transformation effort. Option A is incorrect because the COPY command cannot directly load from on-premises storage; data must first be staged in Amazon S3 in a supported format. Option C is incorrect because AWS DMS is designed for migrating relational databases, not proprietary file formats. Option D is incorrect because Amazon Kinesis Data Firehose is for streaming real-time data, not batch migration of existing large-scale data.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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 |
