The answer is to change the worker type from Standard to G.2X. This directly addresses out-of-memory errors in executors because G.2X workers provide four times the memory (16 GB) of a Standard worker (4 GB), allowing larger datasets to be processed without spilling to disk or failing. On the AWS Certified Data Engineer Associate DEA-C01 exam, this scenario tests your understanding of AWS Glue worker types and their memory allocations—a common trap is to increase the number of workers instead of upgrading the worker type, which adds parallelism but not per-executor memory. Remember that for memory-bound jobs, G.1X (8 GB) or G.2X (16 GB) are the correct levers, while Standard workers are best for lightweight ETL. Memory tip: think "G" for "Gigabytes"—G.2X gives you double the memory of G.1X and quadruple that of Standard.
DEA-C01 Data Ingestion and Transformation Practice Question
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.
Network Topology
A data engineer reviews the Glue job configuration. The job fails when processing large datasets. The error message indicates out-of-memory in the executors. Which change to the job configuration will most directly address this issue?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Change the worker type from Standard to G.2X.
The job uses 5 workers of Standard type. To increase memory, the engineer should use G.1X or G.2X worker types which provide more memory per worker, or increase the number of workers. Among options, changing worker type to G.2X directly increases memory.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Change the worker type from Standard to G.2X.
Why this is correct
G.2X workers have more memory (8 GB vs 4 GB), directly addressing OOM.
Related concept
Read the scenario before looking for a memorised answer.
✗
Increase the timeout from 30 to 60 minutes.
Why it's wrong here
Timeout does not affect memory.
✗
Increase the number of workers from 5 to 10.
Why it's wrong here
More workers may help parallelism but each worker still has the same memory; the root issue is per-worker memory.
✗
Set MaxRetries to 3.
Why it's wrong here
Retries don't fix the memory issue.
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 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.
