SCS-C02 Identity and Access Management Practice Question
This SCS-C02 practice question tests your understanding of identity and access management. 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.
Refer to the exhibit. An EC2 instance is launched with an instance profile that references this role. The application on the instance tries to list objects in 'my-bucket' but 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 S3 bucket has a bucket policy that denies access.
Option C is correct because the policy only allows s3:ListBucket on the bucket, but to list objects, the action s3:ListBucket is correct, but the resource arn:aws:s3:::my-bucket does not include the objects. To list objects, you also need s3:ListBucket on the bucket ARN and s3:GetObject on the objects? Actually, s3:ListBucket is for listing bucket contents, and it requires the bucket ARN. The error might be because the policy does not allow s3:GetObject for the objects, but the question says 'list objects' - that's s3:ListBucket. However, the policy allows s3:ListBucket on the bucket, so that should work. Option A is wrong because the trust policy allows EC2. Option B is wrong because the role has a policy. Option D is wrong because bucket policy is not mentioned. Actually, the most likely cause is that the bucket policy denies the access. So option D is correct.
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 trust policy does not allow the EC2 service to assume the role.
Why it's wrong here
The trust policy does allow EC2.
✗
The policy does not grant s3:GetObject permission.
Why it's wrong here
The action needed is s3:ListBucket, which is granted.
✓
The S3 bucket has a bucket policy that denies access.
Why this is correct
An explicit deny in the bucket policy would override the role's allow.

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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
