This DEA-C01 practice question tests your understanding of data ingestion and transformation. 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 data pipeline uses AWS Glue to process large CSV files. The team notices that some jobs fail with out-of-memory errors. Which TWO configuration changes can help mitigate this issue?
Reduce the number of DPUs to limit concurrency.
Why wrong: Would reduce memory, worsening issue.
Increase the number of DPUs for the Glue job.
More DPUs provide more memory.
Enable Glue job autoscaling.
Dynamically adjusts resources to meet demand.
Convert input files from CSV to Parquet.
Why wrong: May help but is an external change, not a configuration fix.
Enable job bookmarks.
Why wrong: Does not affect memory.
Answer choices
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 for the Glue job.
Options A and D are correct: increasing DPUs and enabling autoscaling provide more memory. Option B (reducing DPUs) would worsen the problem. Option C (conversion to Parquet) may reduce memory but is not a direct configuration change for the Glue job. Option E (job bookmarks) does not affect memory.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Reduce the number of DPUs to limit concurrency.
Why it's wrong here
Would reduce memory, worsening issue.
Increase the number of DPUs for the Glue job.
Why this is correct
More DPUs provide more memory.

Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
