- A
Increase the Glue job timeout setting to 24 hours.
Why wrong: Longer timeout does not speed up processing.
- B
Enable S3 Transfer Acceleration on the source bucket.
Why wrong: Transfer Acceleration improves upload speed, not Glue job processing.
- C
Increase the number of DPUs allocated to the Glue job.
More DPUs provide more parallelism and reduce runtime.
- D
Convert the input data from CSV to Parquet format.
Why wrong: Parquet improves read performance but may not significantly reduce processing time if the bottleneck is compute.

SAP-C02 Continuous Improvement for Existing Solutions Practice Question
This SAP-C02 practice question tests your understanding of continuous improvement for existing solutions. 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 has a data pipeline that uses AWS Glue to process large datasets in Amazon S3. The pipeline runs daily and takes over 12 hours to complete. The company wants to reduce the processing time. Which approach would be MOST effective?
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
✓
Increase the number of DPUs allocated to the Glue job.
Option C is correct because increasing the number of DPUs (data processing units) allocated to the Glue job allows for greater parallelism, which directly reduces processing time for CPU-bound or memory-bound workloads. Option A is incorrect because increasing the timeout does not improve performance; it only prevents the job from failing due to time limits. Option B is incorrect because S3 Transfer Acceleration speeds up data transfer to S3, not the processing within Glue. Option D is incorrect because while converting to Parquet can improve read performance and reduce data volume, it does not address the core processing bottleneck if the job is compute-intensive; the most effective immediate step is to increase DPUs.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

- ✗
Enable S3 Transfer Acceleration on the source bucket.
Why it's wrong here
Transfer Acceleration improves upload speed, not Glue job processing.
- ✓
Increase the number of DPUs allocated to the Glue job.
Why this is correct

Why it's wrong here
Parquet improves read performance but may not significantly reduce processing time if the bottleneck is compute.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
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 |
