The answer is that the download will fail with an access denied error. This occurs because the bucket policy includes a condition that denies all s3:GetObject actions when aws:SecureTransport is false, meaning any HTTP request is explicitly blocked regardless of the requesting account. Enforcing HTTPS for S3 access using bucket policy is a core security control tested on the AWS Certified Data Engineer Associate DEA-C01 exam, often appearing in scenarios that distinguish between encryption in transit and encryption at rest. A common trap is confusing this with server-side encryption (SSE) requirements—this policy does not check for encryption at rest, only the transport protocol. Remember the mnemonic: “SecureTransport denies the insecure sort,” so if the request comes over HTTP, it gets blocked.
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.
Network Topology
A data engineer runs the command shown in the exhibit to check the bucket policy. A user from another AWS account is trying to download an object using HTTP (not HTTPS). 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 download will fail with an access denied error
Option B is correct because the bucket policy denies all actions when aws:SecureTransport is false (i.e., HTTP). Therefore, HTTP requests are denied. Option A is wrong because the policy denies HTTP requests. Option C is wrong because the policy does not require encryption at rest. Option D is wrong because the policy explicitly denies HTTP.
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 download will succeed because the principal is not specified
Why it's wrong here
Principal: * applies to all users.
✓
The download will fail with an access denied error
Read the scenario before looking for a memorised answer.
✗
The download will succeed if the object is encrypted at rest
Why it's wrong here
Encryption at rest does not affect in-transit requirements.
✗
The download will succeed because the policy only denies write operations
Why it's wrong here
The policy denies s3:* for all actions.
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 to study next
Got this wrong? Here's your next step.
Identify which DEA-C01 exam domain this question belongs to, then review the specific concept being tested. Practise related questions in that domain and focus on understanding why each wrong answer is tempting — not just why the correct answer is right.

What is the correct answer to this question?
The correct answer is: The download will fail with an access denied error — Option B is correct because the bucket policy denies all actions when aws:SecureTransport is false (i.e., HTTP). Therefore, HTTP requests are denied. Option A is wrong because the policy denies HTTP requests. Option C is wrong because the policy does not require encryption at rest. Option D is wrong because the policy explicitly denies HTTP.
