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. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.

Exhibit

resource "google_organization_policy" "restrict_vm_external_ip" {
  org_id     = "123456789"
  constraint = "constraints/compute.vmExternalIpAccess"
  boolean_policy {
    enforced = true
  }
}

Refer to the exhibit. A DevOps engineer is bootstrapping a Google Cloud organization and wants to ensure that no Compute Engine VM instances can have external IP addresses. The engineer applies this Terraform configuration. What is the effect of this configuration on the organization?

Exhibit

resource "google_organization_policy" "restrict_vm_external_ip" {
  org_id     = "123456789"
  constraint = "constraints/compute.vmExternalIpAccess"
  boolean_policy {
    enforced = true
  }
}

A
It blocks external IP access for all VMs in all projects under the organization.
The boolean policy with enforced=true applies at the organization level, affecting all projects and folders.
B
It requires a separate script to enforce the policy on existing VMs.
Why wrong: The policy is enforced automatically for all VMs, both new and existing.
C
It blocks external IP access only for the first project created in the organization.
Why wrong: The organization policy applies to the entire organization, not just the first project.
D
It blocks both internal and external IP access for all VMs.
Why wrong: The constraint specifically targets external IP access; internal IPs are unaffected.

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

✓

It blocks external IP access for all VMs in all projects under the organization.

The Terraform configuration uses a Google Cloud Organization Policy constraint (`compute.vmExternalIpAccess`) set to `true` in a list policy with `deny` as the enforcement action. This blocks external IP access for all Compute Engine VM instances across all projects within the organization, as organization policies are inherited by all child projects unless overridden. The policy applies to both new and existing VMs, as it is enforced at the resource creation and modification level.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often confuse organization policy inheritance with project-level overrides, thinking the policy only applies to the first project or requires manual reapplication, when in fact it is automatically inherited by all projects and enforced on existing VMs via lifecycle hooks.

Detailed technical explanation

How to think about this question

The `compute.vmExternalIpAccess` constraint is a list policy that, when set to `deny` with all values allowed (or a specific list), prevents VMs from having external IP addresses. Under the hood, Google Cloud's Organization Policy service evaluates this constraint during the `instances.insert` and `instances.start` API calls, rejecting the operation if the VM would be assigned an external IP. A real-world scenario where this matters is in a security-critical environment where data exfiltration via public IPs must be prevented, and the policy ensures that even if a developer tries to create a VM with an external IP, the request fails at the API level.

KKey Concepts to Remember

Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.

TExam Day Tips

Watch for words such as best, first, most likely and least administrative effort.
Review why wrong options are wrong, not only why the correct option is correct.

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.
