The answer is that a lower-level policy at the project or folder hierarchy overrode the organization-level deny. This happens because Google Cloud’s organization policy hierarchy allows child nodes to explicitly set a policy that contradicts the parent, effectively bypassing the inherited restriction. In your scenario, even though `compute.vmExternalIpAccess` is denied at the organization level, the `devops-dev` project likely had a policy set to `Allow` or used a custom deny list that excluded certain service accounts, giving the developer permission to create an instance with an external IP. On the Google Professional Cloud DevOps Engineer exam, this tests your understanding of policy inheritance and override behavior—a common trap is assuming organization-level policies are absolute. Remember that policies are inherited by default but can be overridden at any lower level (folder or project) unless the parent policy uses a `Deny` with a specific condition like `enforce: true`. Memory tip: “Parent says no, child says go—check the project-level policy to know.”
PCDOE Practice Question: Bootstrapping a Google Cloud organization for DevOps
This PCDOE practice question tests your understanding of bootstrapping a google cloud organization for devops. 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.
Your organization is bootstrapping a new Google Cloud environment for a DevOps team. The team consists of 15 engineers who will be working on multiple microservices deployed across several projects. You have created a folder called 'devops' under the organization node. Within this folder, you plan to create three projects: 'devops-dev', 'devops-staging', and 'devops-prod'. You want to enforce that all resources in these projects are created in a specific region (us-central1) and that no external IP addresses can be assigned to Compute Engine instances. Additionally, you want to ensure that all service accounts used by the applications have minimal permissions. After setting up the organization policies, you notice that a developer was able to create a Compute Engine instance with an external IP in the 'devops-dev' project. You check the organization policy constraints and find that the constraint 'compute.vmExternalIpAccess' is set to 'Deny' at the organization level, but the developer bypassed it. What is the most likely reason?

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The project 'devops-dev' has a policy that overrides the organization-level deny.
Option A is correct because organization policies can be overridden at a lower level in the resource hierarchy. Even though the constraint 'compute.vmExternalIpAccess' is set to 'Deny' at the organization level, a policy at the project level (or folder level) with a higher priority or a different binding can allow external IPs. In Google Cloud, organization policies are inherited by default, but a child policy can override the parent if it is explicitly set to 'Allow' or if the deny list is not enforced. The developer likely had a project-level policy that allowed external IPs, bypassing the organization-level deny.
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.
✓
The project 'devops-dev' has a policy that overrides the organization-level deny.
Why this is correct
Project-level policies override organization-level policies if they are less restrictive.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
The organization policy has not propagated to all projects yet.
Why it's wrong here
Organization policies propagate quickly; delay is unlikely.
✗
The developer used the wrong constraint name; the correct constraint is 'compute.restrictExternalIp'.
Why it's wrong here
The correct constraint is 'compute.vmExternalIpAccess'.
✗
The developer tagged the instance with a tag that exempts it from the organization policy.
Why it's wrong here
Tags can be used in conditions, but if the policy is set to deny all, tags won't bypass unless there is a condition allowing it.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the misconception that organization policies are absolute and cannot be overridden, but in reality, policies can be overridden at lower hierarchy levels unless explicitly configured to be enforced with a 'denyAll' or by using a boolean constraint that cannot be overridden.
Detailed technical explanation
How to think about this question
Google Cloud organization policies use a hierarchical inheritance model where policies at a higher level (e.g., organization) are inherited by lower levels (folders, projects) unless explicitly overridden. The 'compute.vmExternalIpAccess' constraint is a list constraint that can be set to 'Deny' with a list of allowed values (e.g., specific VMs or projects). If a project-level policy sets the same constraint to 'Allow' or modifies the deny list, it overrides the organization-level deny. This is a common misconfiguration when teams do not enforce policy at the organization level with a 'Deny' that cannot be overridden, such as using a boolean constraint or setting the constraint with a 'denyAll' value.

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 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.
