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. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
A company wants to enforce that all service accounts are created with a specific naming convention (e.g., prefix 'sa-'). What is the most efficient way to enforce this?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a Cloud Function that monitors and remediates non-compliant service accounts.
Option B is correct because a Cloud Function can be triggered by a Pub/Sub notification on the `google.cloud.audit.log.v1.activityLog` topic for `google.iam.admin.v1.CreateServiceAccount` events. The function can immediately delete or disable non-compliant service accounts that do not match the 'sa-' prefix, providing automated enforcement without blocking legitimate creation attempts. This approach is event-driven and avoids the latency or complexity of periodic scanning.
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 role that restricts service account creation to users who follow the naming convention.
Why it's wrong here
Roles cannot enforce naming conventions.
✓
Use a Cloud Function that monitors and remediates non-compliant service accounts.
Why this is correct
A Cloud Function can detect violations and automatically delete or rename.
Related concept
Read the scenario before looking for a memorised answer.
✗
Use an organization policy constraint with a condition on the service account name.
Why it's wrong here
No built-in organization policy constraint exists for naming.
✗
Use a folder-level attribute with a policy on service account names.
Why it's wrong here
Folder attributes cannot enforce naming.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume organization policy constraints can enforce naming conventions because they are familiar with resource location or domain restrictions, but Google Cloud's organization policies do not support regex or prefix matching on IAM resource names.
Detailed technical explanation
How to think about this question
Under the hood, the Cloud Function receives an AuditLog entry with the `resourceName` field containing the full service account email (e.g., `projects/my-project/serviceAccounts/sa-myaccount@...`). The function can parse the prefix using a regex and call the `iam.serviceAccounts.delete` method with the `name` field set to the same `resourceName`. A subtle behavior is that the Cloud Function must have the `iam.serviceAccounts.delete` permission and the service account being deleted must not be the function's own identity, otherwise a self-deletion loop could occur.

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.
