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
✓
Full access to the bucket except delete.
The IAM policy grants the user s3:GetObject and s3:ListBucket permissions, which allow reading objects and listing the bucket, but explicitly denies s3:DeleteObject. Since an explicit deny overrides any allow, the effective permission is full access except delete. Option D is correct because the user can perform all actions except deleting objects.
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.

No access to the bucket.
Why it's wrong here
Other actions are allowed.
✗
Full access to the bucket including delete.
Why it's wrong here
Delete is denied.
✗
Read-only access to the bucket.
Why it's wrong here
Write actions are allowed.
✓
Full access to the bucket except delete.
Why this is correct
Explicit Deny overrides Allow.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often overlook the explicit deny statement and assume that because the policy grants read and list permissions, the user has full read access, missing that the deny on delete restricts the effective permissions to full access except delete.
Detailed technical explanation
How to think about this question
IAM policy evaluation logic follows an explicit deny override: if a policy statement explicitly denies an action, that deny takes precedence over any allows, even from other policies. This is governed by the AWS IAM policy evaluation engine, which processes all applicable policies (identity-based, resource-based, etc.) and uses a default deny, then allows, then explicit deny logic. In practice, this means a single explicit deny for s3:DeleteObject in any policy attached to the user will block delete operations, regardless of other permissions.

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: Full access to the bucket except delete. — The IAM policy grants the user s3:GetObject and s3:ListBucket permissions, which allow reading objects and listing the bucket, but explicitly denies s3:DeleteObject. Since an explicit deny overrides any allow, the effective permission is full access except delete. Option D is correct because the user can perform all actions except deleting objects.
