The correct answer is to request a service quota increase for concurrent executions. This resolves the Step Function execution throttled error because AWS Step Functions enforces a default limit on how many state machine executions can run simultaneously in an AWS account per Region; when this concurrency ceiling is hit, new executions are throttled with that specific error. On the AWS Certified Data Engineer Associate DEA-C01 exam, this scenario tests your understanding of service quotas versus API rate limits—a common trap is confusing execution throttling with API throttling, which would require adjusting API rate limits instead. Remember that Step Functions execution throttling is a concurrency issue, not a request-per-second issue, so the fix is always a quota increase, not reducing steps or adding CloudWatch alarms. Memory tip: think “concurrent executions = quota increase,” as throttling here is about how many runs happen at once, not how fast they start.
DEA-C01 Data Operations and Support Practice Question
This DEA-C01 practice question tests your understanding of data operations and support. 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 engineer is troubleshooting a step function that orchestrates ETL jobs. The state machine fails with 'State Machine Execution Throttled' error. What should the engineer do to resolve this?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Request a service quota increase for concurrent executions.
Option C is correct because the throttling is likely due to exceeding the default concurrent execution limit. Requesting a limit increase from AWS Support is the proper solution. Option A is wrong because reducing the number of steps does not affect concurrent execution limits. Option B is wrong because CloudWatch alarms only monitor, not resolve throttling. Option D is wrong because the error is about execution throttling, not API throttling, so adjusting API rate limits is not relevant.
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.
✗
Reduce the number of steps in the state machine.
Why it's wrong here
This does not address concurrent execution limits.
✗
Set up a CloudWatch alarm to detect throttling and retry.
Why it's wrong here
Alarms monitor but do not prevent throttling.
✗
Adjust the API rate limits in the state machine definition.
Why it's wrong here
API rate limits are for API calls, not execution throttling.
✓
Request a service quota increase for concurrent executions.
Why this is correct
Increasing the limit resolves the throttling.

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.

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

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.
