DEA-C01 Data Operations and Support Practice Question
This DEA-C01 practice question tests your understanding of data operations and support. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 has this IAM policy attached to their user. They are trying to create an Amazon EMR cluster with a custom service role 'EMR_CustomRole'. What will happen?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The cluster creation will fail with an 'Access Denied' error for iam:PassRole.
Option B is correct because the policy only allows iam:PassRole for the specific role 'EMR_DefaultRole', not for 'EMR_CustomRole'. The elasticmapreduce:* action allows creating clusters, but the PassRole will fail. Option A (full success) is incorrect. Option C (EMR not allowed) is false. Option D (PassRole not needed) is false.
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.
✗
The cluster creation will fail because elasticmapreduce:* is too broad.
Why it's wrong here
Broad permissions are allowed; the issue is with PassRole.
✗
The cluster creation will succeed because elasticmapreduce:* is allowed.
Why it's wrong here
PassRole permission is required for EMR to assume the service role; the policy does not allow passing the custom role.
✓
The cluster creation will fail with an 'Access Denied' error for iam:PassRole.
Why this is correct
The policy restricts PassRole to only the default role, so passing a custom role is denied.

Read the scenario before looking for a memorised answer.
✗
The cluster creation will succeed because PassRole is not required for EMR.
Why it's wrong here
PassRole is required for EMR to assume the service role.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
