This DEA-C01 practice question tests your understanding of data store management. 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
✓
It allows the DataLakeRole to read and write objects, but only over HTTPS.
Option B is correct because the bucket policy uses a condition key `aws:SecureTransport` set to `true`, which restricts access to HTTPS (TLS) connections only. The `Principal` is `DataLakeRole`, and the `Action` includes `s3:GetObject` and `s3:PutObject`, so the policy allows that role to read and write objects exclusively over HTTPS, enforcing encrypted data in transit.
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.
✗
It enforces server-side encryption for all objects written to the bucket.
Why it's wrong here
The policy does not mention SSE; it only requires HTTPS.
✓
It allows the DataLakeRole to read and write objects, but only over HTTPS.
Why this is correct
The allow statement grants GetObject and PutObject to the role; the deny statement blocks non-HTTPS requests for everyone.
Related concept
Read the scenario before looking for a memorised answer.
✗
It allows anonymous access to the bucket for HTTPS requests.
Why it's wrong here
The policy does not grant any permissions to anonymous principals.
✗
It denies all access to the bucket except for requests from the DataLakeRole.
Why it's wrong here
The policy allows the DataLakeRole, but the deny statement only applies to non-HTTPS requests, not all requests.
Common exam traps
Common exam trap: answer the scenario, not the keyword
AWS often tests the distinction between encryption in transit (HTTPS/TLS) and encryption at rest (SSE), leading candidates to confuse the `aws:SecureTransport` condition with server-side encryption requirements.
Detailed technical explanation
How to think about this question
The `aws:SecureTransport` condition key evaluates the `TLSVersion` of the request; if set to `true`, only requests using TLS 1.0 or higher are allowed. This policy does not affect encryption at rest (SSE-S3, SSE-KMS, or SSE-C), which is a separate requirement often enforced via `s3:x-amz-server-side-encryption` or a bucket default encryption setting. In real-world scenarios, combining this with a bucket default encryption policy ensures both in-transit and at-rest encryption compliance.

TExam Day Tips
→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 is the correct answer to this question?
The correct answer is: It allows the DataLakeRole to read and write objects, but only over HTTPS. — Option B is correct because the bucket policy uses a condition key `aws:SecureTransport` set to `true`, which restricts access to HTTPS (TLS) connections only. The `Principal` is `DataLakeRole`, and the `Action` includes `s3:GetObject` and `s3:PutObject`, so the policy allows that role to read and write objects exclusively over HTTPS, enforcing encrypted data in transit.
