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.
When bootstrapping a Google Cloud organization for DevOps, which THREE steps are essential to set up a secure CI/CD foundation using Cloud Build?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a Cloud Source Repository for each application's code.
Creating a Cloud Source Repository for each application's code is essential because it provides a dedicated, version-controlled repository that integrates natively with Cloud Build triggers. This ensures that each application has its own isolated codebase, enabling precise CI/CD pipelines without cross-application interference.
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.
✓
Create a Cloud Source Repository for each application's code.
Why this is correct
Repositories are needed to host source code and trigger builds.
Related concept
Read the scenario before looking for a memorised answer.
✓
Set up a trigger that automatically builds on each commit to the main branch.
Why this is correct
Automation is core to CI/CD.
Related concept
Read the scenario before looking for a memorised answer.
✗
Disable default service accounts in all projects.
Why it's wrong here
Good practice, but not essential for initial CI/CD foundation.
✓
Enable the Cloud Build API and grant the Cloud Build service account the necessary roles (e.g., Cloud Run Admin, Artifact Registry Writer).
Why this is correct
Necessary for Cloud Build to operate and deploy.
Related concept
Read the scenario before looking for a memorised answer.
✗
Configure VPC Service Controls for all projects.
Why it's wrong here
Important for security, but not a prerequisite for basic CI/CD setup.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the distinction between 'essential' steps for a specific service (Cloud Build) versus general security best practices, leading candidates to select VPC Service Controls or disabling default service accounts as mandatory when they are actually optional or later-stage configurations.
Detailed technical explanation
How to think about this question
Cloud Source Repositories are Git repositories hosted in Google Cloud that automatically mirror to Cloud Build triggers, enabling event-driven builds on push. Under the hood, Cloud Build uses a Pub/Sub topic to listen for repository changes, and the trigger configuration specifies branch patterns (e.g., ^main$) to filter commits. In a real-world scenario, a monorepo might use multiple triggers per repository, but for a secure foundation, per-application repos enforce least privilege and simplify IAM bindings.
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.
