This DVA-C02 practice question tests your understanding of development with aws services. 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 attached to a user. What is the effect when the user tries to download an object from the 'confidential' folder in 'my-bucket' from an IP address within the 192.0.2.0/24 range?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The request is allowed.
The IAM policy includes both an Allow statement and a Deny statement. The Allow statement grants `s3:GetObject` for the `confidential` folder in `my-bucket` when the request originates from the IP range 192.0.2.0/24. The Deny statement denies the same action for requests from outside that range. Since the user's IP is within the allowed range, the Allow condition is satisfied, and the Deny does not apply. Thus, the request is allowed, making Option C correct.
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 request is denied.
Why it's wrong here
The Deny condition excludes this IP range.
✗
The request results in an error due to conflicting statements.
Why it's wrong here
There is no conflict; the policy is evaluated correctly.
✓
The request is allowed.
Why this is correct
The Deny condition is not satisfied, so the Allow applies.

Read the scenario before looking for a memorised answer.
✗
The request is denied because the Deny statement overrides the Allow.
Why it's wrong here
The Deny condition is not met, so it does not apply.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume any request to a 'confidential' folder is automatically denied, or they forget that an explicit Allow with a matching condition overrides the implicit deny, leading them to incorrectly choose Option A or D.
Detailed technical explanation
How to think about this question
IAM policy evaluation logic follows a default implicit deny, where any request not explicitly allowed is denied. However, when an explicit Allow matches the request (including all conditions), it overrides the implicit deny. In this scenario, the `aws:SourceIp` condition key is evaluated against the requester's IP; if the IP falls within 192.0.2.0/24, the Allow is granted. Note that if an explicit Deny existed for the same action, it would take precedence regardless of conditions, but here no Deny is present.

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: The request is allowed. — The IAM policy includes both an Allow statement and a Deny statement. The Allow statement grants `s3:GetObject` for the `confidential` folder in `my-bucket` when the request originates from the IP range 192.0.2.0/24. The Deny statement denies the same action for requests from outside that range. Since the user's IP is within the allowed range, the Allow condition is satisfied, and the Deny does not apply. Thus, the request is allowed, making Option C correct.
