SAP-C02 Continuous Improvement for Existing Solutions Practice Question
This SAP-C02 practice question tests your understanding of continuous improvement for existing solutions. 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 company is using Amazon S3 to store sensitive data. The security team requires that all data be encrypted at rest using server-side encryption with AWS KMS. The company also needs to ensure that any attempt to upload an unencrypted object is blocked. How can the company enforce this requirement?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a bucket policy that denies s3:PutObject if the request does not include the x-amz-server-side-encryption header with value aws:kms
Option B is correct because a bucket policy that denies PutObject without x-amz-server-side-encryption header set to aws:kms will enforce encryption at upload time. Option A is not possible at the bucket level. Option C (default encryption) does not enforce on existing uploads if the header is omitted. Option D (CloudTrail) is detective, not preventive.
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.
✓
Use a bucket policy that denies s3:PutObject if the request does not include the x-amz-server-side-encryption header with value aws:kms
Why this is correct
This policy condition ensures encryption is used.
Related concept
Read the scenario before looking for a memorised answer.
✗
Enable default encryption on the bucket with AWS KMS
Why it's wrong here
Default encryption applies only if the request does not specify encryption; it does not block unencrypted uploads.
✗
Use AWS CloudTrail to monitor PutObject calls and alert on unencrypted uploads
Why it's wrong here
This is detective, not preventive.
✗
Enable S3 Object Lock on the bucket
Why it's wrong here
Object Lock prevents deletion, not encryption enforcement.
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.
