The answer is that the developer’s request matches the condition in the Deny statement, which overrides the Allow. This happens because AWS IAM policy deny condition override logic dictates that any explicit Deny always takes precedence over any Allow, even when the request includes a matching tag. In this scenario, the Deny statement specifically targets requests where the tag ‘project’ equals ‘alpha’, and since the developer’s request meets that condition, access is blocked regardless of the broader Allow. On the Certified Associate in Project Management CAPM exam, this tests your understanding of IAM policy evaluation logic, particularly how explicit Denies can override Allows when conditions are met. A common trap is assuming that a matching Allow tag will grant access, but the key is that Deny statements are absolute. Remember the mnemonic: “Deny always denies, no matter the tag’s size.”
CAPM Agile Frameworks and Methodologies Practice Question
This CAPM practice question tests your understanding of agile frameworks and methodologies. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
Refer to the exhibit. An Agile team used this IAM policy to control access to an S3 bucket. A developer reports that they cannot access an object in the 'confidential' folder. Their request includes the tag 'project' with value 'alpha'. What is the most likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The developer's request matches the condition in the Deny statement.
The deny statement applies when the request tag 'project' equals 'alpha', which overrides the allow. Option B correctly identifies this condition. Option A is incorrect because the policy syntax is valid. Option C is incorrect because the allow statement grants general access. Option D is irrelevant.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
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 developer is not authorized for any s3:GetObject action.
Why it's wrong here
The Allow statement covers all objects, so the developer is authorized for non-confidential objects.
✓
The developer's request matches the condition in the Deny statement.
Why this is correct
The Deny statement explicitly blocks access when the tag condition is met.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Standard ACLs match source addresses.
✗
The object is located in a different AWS region.
Why it's wrong here
Region does not affect policy evaluation.
Common exam traps
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
Standard ACLs match source addresses.
Extended ACLs can match source, destination, protocol and ports.
The first matching ACL entry is used.
There is usually an implicit deny at the end.
TExam Day Tips
→Check inbound versus outbound direction.
→Read the ACL from top to bottom.
→Look for a broader permit or deny above the intended line.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Real-world example
How this comes up in practice
A security administrator must allow nursing staff to reach a patient records server while blocking access from the guest Wi-Fi VLAN. After applying an extended ACL, traffic is still blocked from nursing workstations. The ACL was applied outbound instead of inbound on the wrong interface. Questions like this test ACL direction and placement rules.
What to study next
Got this wrong? Here's your next step.
Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related CAPM ACL questions on filtering logic and placement.

What is the correct answer to this question?
The correct answer is: The developer's request matches the condition in the Deny statement. — The deny statement applies when the request tag 'project' equals 'alpha', which overrides the allow. Option B correctly identifies this condition. Option A is incorrect because the policy syntax is valid. Option C is incorrect because the allow statement grants general access.
