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. 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.
During bootstrapping, a DevOps engineer wants to ensure that all new projects automatically have a set of APIs enabled, such as Cloud Resource Manager API and Cloud Billing API. They also want to enforce that certain APIs cannot be disabled accidentally. What is the most efficient way to achieve this?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use organization policies to define the constraints 'compute.requireOsLogin' and 'serviceuser.services' to restrict/enable APIs.
Option C is correct because organization policies in Google Cloud allow you to enforce constraints at the organization, folder, or project level. The `serviceuser.services` constraint can be used to specify a list of APIs that must be enabled (or cannot be disabled) on all projects under the policy scope, ensuring compliance without manual intervention or additional infrastructure.
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.
✗
Use a custom Cloud Function that runs every time a project is created and enables the APIs.
Why it's wrong here
While possible, it's not as reliable as organization policies which are enforced natively.
✗
Grant the roles/serviceusage.serviceUsageAdmin role to the DevOps team and have them manually enable APIs when creating projects.
Why it's wrong here
Manual processes are error-prone and not enforced.
✓
Use organization policies to define the constraints 'compute.requireOsLogin' and 'serviceuser.services' to restrict/enable APIs.
Why this is correct
Organization policies can enforce required services across the hierarchy.

✗
Create a folder with a 'Required APIs' setting that applies to all child projects.
Why it's wrong here
No such folder setting exists; organization policies are used for this.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse folder-level settings with organization policies, assuming folders have a built-in 'Required APIs' feature, when in reality only organization policies can enforce API enablement and disablement restrictions across projects.
Detailed technical explanation
How to think about this question
The `serviceuser.services` constraint is a list constraint that can be set to `deny` all services except those explicitly allowed, or to `allow` only specified services. When used in conjunction with the `constraints/serviceuser.services` policy, you can define a list of required APIs (e.g., `cloudresourcemanager.googleapis.com`, `cloudbilling.googleapis.com`) that must be enabled and cannot be disabled by any project-level role, as the policy overrides project-level permissions. This is enforced by the Resource Manager hierarchy, ensuring inheritance to all child projects.

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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
