- A
Grant roles/owner at the folder level
Why wrong: Too broad; owner grants full control over all resources.
- B
Grant roles/compute.admin at the project level for each project
Why wrong: Too broad (includes all compute permissions) and requires multiple grants.
- C
Grant roles/compute.networkAdmin at the folder level
Why wrong: This role does not include permissions to create firewall rules.
- D
Grant roles/compute.securityAdmin at the folder level
Correct: folder-level grant covers all descendant projects with minimal permissions for firewall rules.
Google ACE Configuring Access and Security Practice Question
This ACE practice question tests your understanding of configuring access and 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.
An organization has multiple projects under a folder. They want to grant a network admin the ability to create firewall rules in all projects in the folder. Which IAM policy binding achieves this with least privilege?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.

"least"Why it matters: You want the option with minimum overhead, fewest steps, or lowest impact — not the most feature-rich or comprehensive answer.
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
Grant roles/compute.securityAdmin at the folder level
Grant the roles/compute.securityAdmin role at the folder level. This allows managing firewall rules across all projects under that folder. Granting at project level would require adding the role to each project individually. The compute.networkAdmin role does not include firewall rule management.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.

- ✗
Grant roles/compute.networkAdmin at the folder level
Why it's wrong here
This role does not include permissions to create firewall rules.
- ✓
Grant roles/compute.securityAdmin at the folder level
Why this is correct
Correct: folder-level grant covers all descendant projects with minimal permissions for firewall rules.
Clue confirmation
The clue word "least" in the question point toward this answer.

Common exam traps
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
- Authentication checks who the user is.
- Authorization controls what the user is allowed to do after login.
- Privilege levels affect access to EXEC and configuration commands.
- AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
- Do not assume successful login means full administrative access.
- Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
- Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
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 Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related ACE questions on access control and AAA configuration.
