This DVA-C02 practice question tests your understanding of security. 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
✓
All requests to the bucket must use HTTPS; otherwise, they are denied.
The bucket policy includes a `Deny` effect with a `StringNotEquals` condition on `aws:SecureTransport`, which denies any request that does not use HTTPS. Since the `Principal` is set to `*`, this applies to all users, including anonymous users. Therefore, any request made over HTTP is denied, effectively requiring HTTPS for all access.
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.
✗
Anonymous users are allowed to read objects.
Why it's wrong here
The policy does not grant any allow, only denies non-HTTPS.
✗
Only write requests are denied if not using HTTPS.
Why it's wrong here
The action is s3:* (all actions).
✓
All requests to the bucket must use HTTPS; otherwise, they are denied.
Why this is correct
The condition denies access when SecureTransport is false.

✗
The policy has no effect because it uses Deny.
Why it's wrong here
Deny is effective.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often think a `Deny` statement with a condition is ineffective or only applies to specific actions, but in reality, the `Deny` with `StringNotEquals` on `aws:SecureTransport` explicitly blocks all non-HTTPS requests, making it a powerful enforcement mechanism.
Detailed technical explanation
How to think about this question
The `aws:SecureTransport` condition key evaluates the `True` or `False` value of the `SecureTransport` property of the request, which indicates whether the request was sent over TLS. When combined with `StringNotEquals`, the policy denies requests where `SecureTransport` is not `true`, effectively blocking HTTP. This is a common pattern for enforcing encryption in transit, and it overrides any `Allow` statements that might otherwise grant access over HTTP.

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: All requests to the bucket must use HTTPS; otherwise, they are denied. — The bucket policy includes a `Deny` effect with a `StringNotEquals` condition on `aws:SecureTransport`, which denies any request that does not use HTTPS. Since the `Principal` is set to `*`, this applies to all users, including anonymous users. Therefore, any request made over HTTP is denied, effectively requiring HTTPS for all access.

Variation 1. A developer attaches the above S3 bucket policy to my-bucket. A user tries to upload an object using HTTP (not HTTPS). What will happen?
hard
A.The upload succeeds because the Deny effect only applies if the condition is true
B.The upload succeeds if the user also has an Allow in another policy
✓ C.The upload is denied
D.The upload succeeds because there is no Allow statement
Why C: The correct answer is C. The bucket policy includes a Deny statement that denies s3:PutObject when the condition aws:SecureTransport equals false. Since the user is using HTTP (not HTTPS), SecureTransport is false, so the Deny applies and the upload is denied. Option A is wrong because the Deny effect does apply when the condition is true. Option B is wrong because even if the user has an Allow from another policy, an explicit Deny always overrides any Allow. Option D is wrong because the Deny statement explicitly denies the action; an explicit Deny does not require a matching Allow statement to be effective.
