SAP-C02 Design for New Solutions Practice Question
This SAP-C02 practice question tests your understanding of design for new solutions. 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 company has an S3 bucket with server-side encryption using S3-Managed Keys (SSE-S3). The IAM policy shown in the exhibit is attached to a user. When the user attempts to download an object using the AWS CLI with no encryption headers, the request fails. What is the MOST likely reason?
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 policy condition requires the encryption header in the request.
The policy requires that the request include the encryption header 'x-amz-server-side-encryption: AES256'. SSE-S3 uses AES256, but the condition requires the header to be present in the request. Without the header, the request does not satisfy the condition. Option B is correct. Option A is wrong because the user has GetObject permission. Option C is wrong because the bucket policy does not need to match. Option D is wrong because SSE-S3 is enabled by default.
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 object is encrypted with SSE-KMS, not SSE-S3.
Why it's wrong here
The bucket uses SSE-S3.
✗
The user does not have the s3:GetObject permission.
Why it's wrong here
The policy grants s3:GetObject.
✗
The bucket has a bucket policy that denies all requests.
Why it's wrong here
No information about bucket policy.
✓
The policy condition requires the encryption header in the request.
Why this is correct
The condition 's3:x-amz-server-side-encryption': 'AES256' requires the request to include that header.

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.
