SCS-C02 Management and Security Governance Practice Question
This SCS-C02 practice question tests your understanding of management and security governance. 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 security engineer is troubleshooting a situation where an IAM user is unable to assume a role in a different account. The trust policy of the role allows the user's account to assume the role, and the user has permissions to call AssumeRole. However, the user receives an 'AccessDenied' error. What is the most likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The user's IAM policy does not grant sts:AssumeRole for the target role.
Option B is correct because the user's IAM permissions must explicitly allow the sts:AssumeRole action for the specific role ARN. Option A is wrong because the error would be different if the role did not exist. Option C is wrong because SCPs apply to all principals in the account, but the user already has a policy allowing AssumeRole. Option D is wrong because MFA would result in a different error message.
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 role ARN is incorrect.
Why it's wrong here
If the role ARN were incorrect, the error would indicate that the role does not exist.
✓
The user's IAM policy does not grant sts:AssumeRole for the target role.
Why this is correct
Even if the trust policy allows the account, the user must have explicit permissions to assume the role.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
An SCP in the user's account denies sts:AssumeRole.
Why it's wrong here
SCPs would affect all principals; the user already has an allow policy, so an SCP deny would be unusual.
✗
The role requires MFA and the user has not authenticated with MFA.
Why it's wrong here
If MFA were required, the error message would indicate that condition.
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.
