DEA-C01 Data Security and Governance Practice Question
This DEA-C01 practice question tests your understanding of data security and 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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
PutObject requests are denied unless they include the x-amz-server-side-encryption header set to AES256
The policy denies s3:PutObject if the encryption header is not set to AES256 (SSE-S3). It does not enforce a specific KMS key. It allows uploads with SSE-S3. It denies uploads without encryption or with other encryption types.
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.
✓
PutObject requests are denied unless they include the x-amz-server-side-encryption header set to AES256
Why this is correct
The condition StringNotEquals denies if the header is not AES256, so only requests with AES256 are allowed.
Related concept
Read the scenario before looking for a memorised answer.
✗
All PutObject requests are denied regardless of encryption
Why it's wrong here
The condition only denies when encryption is not AES256, so requests with AES256 are allowed.
✗
All PutObject requests are allowed only if they use SSE-KMS
Why it's wrong here
The condition requires AES256, which is SSE-S3, not SSE-KMS.
✗
The policy has no effect because it does not allow any action
Why it's wrong here
Deny statements are effective; the policy explicitly denies non-compliant requests.
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.
