- A
The user can create instances because the allow policy at the folder level takes precedence over the deny policy at the project level.
Why wrong: Deny policies override allow policies regardless of hierarchy level.
- B
The user can create instances because the project-level deny policy only applies to resources within the project, not to permissions inherited from the folder.
Why wrong: Deny policies apply to all resources in the project and override inherited allows.
- C
The user can create instances because deny policies only block explicit allows, not inherited ones.
Why wrong: Deny policies block all allows, inherited or explicit.
- D
The user cannot create instances because deny policies override allow policies.
Deny policies take precedence over allow policies, so the deny at the project level blocks the inherited allow.
PCSE Practice Question: Configuring Access Within a Cloud Solution Environment
This PCSE practice question tests your understanding of configuring access within a cloud solution environment. 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.
Your organization has an IAM policy at the folder level that grants a user the Compute Admin role. A deny policy at the project level denies the same user the compute.instances.create permission. What is the effective access for this user on the project?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
The user cannot create instances because deny policies override allow policies.
Deny policies always override allow policies. The deny at the project level explicitly denies compute.instances.create, so the user cannot create instances despite the folder-level allow.
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 user can create instances because the allow policy at the folder level takes precedence over the deny policy at the project level.
Why it's wrong here
Deny policies override allow policies regardless of hierarchy level.
- ✗
The user can create instances because the project-level deny policy only applies to resources within the project, not to permissions inherited from the folder.
Why it's wrong here
Deny policies apply to all resources in the project and override inherited allows.
- ✗
The user can create instances because deny policies only block explicit allows, not inherited ones.
Why it's wrong here
Deny policies block all allows, inherited or explicit.
- ✓
The user cannot create instances because deny policies override allow policies.
Why this is correct
Deny policies take precedence over allow policies, so the deny at the project level blocks the inherited allow.
Related concept
Standard ACLs match source addresses.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
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 PCSE ACL questions on filtering logic and placement.
