- A

Cloud Digital Leader How Google Cloud Resources Are Managed Practice Question
This GCDL practice question tests your understanding of how google cloud resources are managed. 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 organization has a folder-level IAM policy that grants the 'roles/compute.instanceAdmin' role to a group. A project under that folder has a policy that denies this role to the same group. What is the effective access for the group on Compute Engine instances in 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 group has no access because the deny overrides the allow
Deny policies override allow policies. Even though the group has an allowed role at the folder level, the explicit deny at the project level takes precedence, so the group will not have the role's permissions on instances in that project.
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 group has no access because the deny overrides the allow
Why this is correct
Deny always overrides allow.
Related concept
Standard ACLs match source addresses.
- ✗
The group has full admin access because the folder policy allows it
Why it's wrong here
Deny policies override allows.
- ✗
The group has view access only
Why it's wrong here
The deny removes all permissions associated with the role.
- ✗
The group retains permissions but cannot modify instances
Why it's wrong here
Deny revokes all permissions in the role.
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 GCDL ACL questions on filtering logic and placement.
