The answer is that the condition key 's3:x-amz-server-side-encryption' applies only to PUT requests, not GET requests. This is because the s3:x-amz-server-side-encryption condition key is designed to enforce encryption settings during object uploads by checking the corresponding request header, but it has no effect on download operations where the encryption header is different. On the AWS Certified Security Specialty SCS-C02 exam, this tests your understanding of how IAM policy conditions map to specific S3 API actions—a common trap is assuming a single encryption condition works for both uploads and downloads. For downloads requiring server-side encryption with customer-provided keys, you must use the 's3:x-amz-server-side-encryption-customer-algorithm' condition key instead. A helpful memory tip: think "PUT in the condition, GET in the permission"—the encryption condition only enforces what goes into the bucket, not what comes out.
SCS-C02 Management and Security Governance Practice Question
This SCS-C02 practice question tests your understanding of management and security governance. 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.
An IAM policy is used to grant access to an S3 bucket. The policy condition requires that objects be retrieved using AES256 encryption. However, users can still download objects without specifying encryption. 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 condition key 's3:x-amz-server-side-encryption' applies only to PUT requests, not GET requests.
Option C is correct because the condition 's3:x-amz-server-side-encryption' is a request header for uploads, not downloads. For downloads, the condition should be 's3:x-amz-server-side-encryption-customer-algorithm' or similar. Option A is incorrect because the resource ARN is correct. Option B is incorrect because S3 supports multiple encryption types. Option D is incorrect because the condition is not null.
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 condition key 's3:x-amz-server-side-encryption' applies only to PUT requests, not GET requests.
Why this is correct
For GET requests, the condition key for server-side encryption is different.
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.
✗
The resource ARN should include the bucket name without the '/*' suffix.
Why it's wrong here
The ARN is correctly formatted.
✗
The condition should use 'Null' instead of 'StringEquals'.
Why it's wrong here
Using 'Null' would allow any encryption value.
✗
The condition should use 'aws:SecureTransport' instead.
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.
