The answer is that the upload fails with an Access Denied error. This occurs because the IAM policy enforces SSE-S3 encryption by requiring the `s3:x-amz-server-side-encryption` header to be set to `AES256` as a condition for the `s3:PutObject` action. When the user attempts to upload an object without specifying any encryption, the request does not include the required header, so the condition in the policy is not satisfied, and AWS denies the action by default. On the AWS Certified SysOps Administrator Associate SOA-C02 exam, this scenario tests your understanding of how IAM policy conditions can enforce encryption at the bucket level, often appearing as a trick where candidates assume S3 will automatically apply default bucket encryption—but the policy explicitly blocks unencrypted requests. A common trap is confusing bucket-level default encryption settings with IAM policy enforcement; remember that IAM conditions evaluate the request headers, not the bucket configuration. Memory tip: "No header, no entry"—if the encryption header is missing, the policy denies the upload.
SOA-C02 Security and Compliance Practice Question
This SOA-C02 practice question tests your understanding of security and compliance. 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 SysOps administrator applies the IAM policy shown in the exhibit to an IAM user. The user tries to upload an object to the S3 bucket without specifying encryption. 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 upload fails with an Access Denied error.
Option B is correct because the policy requires SSE-S3 (AES256), and if the user does not specify encryption, the request does not satisfy the condition, so the action is denied. Option A is wrong because the condition is not met. Option C is wrong because the policy does not allow unencrypted uploads. Option D is wrong because the condition is not met.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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 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.

What is the correct answer to this question?
The correct answer is: The upload fails with an Access Denied error. — Option B is correct because the policy requires SSE-S3 (AES256), and if the user does not specify encryption, the request does not satisfy the condition, so the action is denied. Option A is wrong because the condition is not met. Option C is wrong because the policy does not allow unencrypted uploads. Option D is wrong because the condition is not met.
