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.
A DevOps team is setting up a CI/CD pipeline using Cloud Build. They want the Cloud Build service account to have permission to deploy to Cloud Run within a specific project. Which IAM role should be granted to the Cloud Build service account?
roles/run.admin
This allows deploying and managing Cloud Run services.
roles/run.invoker
Why wrong: This only allows invoking services.
roles/cloudbuild.builds.editor
Why wrong: This is for Cloud Build, not Cloud Run.
roles/iam.serviceAccountUser
Why wrong: This is for using service accounts, not deploying.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
roles/run.admin
The Cloud Build service account needs the `roles/run.admin` role to deploy services to Cloud Run. This role grants full control over Cloud Run resources, including creating, updating, and deleting services, which is required for a CI/CD pipeline to perform deployments. Without this role, the service account would lack the necessary permissions to modify Cloud Run configurations.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
Google Cloud often tests the distinction between roles that grant management permissions (like `roles/run.admin`) versus roles that only grant invocation or build management, leading candidates to mistakenly choose `roles/run.invoker` or `roles/cloudbuild.builds.editor` when deployment is required.
Detailed technical explanation
Under the hood, Cloud Run deployments require the `run.services.create` and `run.services.update` permissions, which are included in `roles/run.admin` but not in `roles/run.invoker` (which only has `run.routes.invoke`). The Cloud Build service account is typically the default compute engine service account (PROJECT_NUMBER-compute@developer.gserviceaccount.com) or a user-managed service account; granting `roles/run.admin` ensures it can call the Cloud Run Admin API (e.g., `POST /v1/{parent}/services`) to deploy new revisions. In a real-world scenario, if the pipeline also needs to manage IAM policies on the Cloud Run service, `roles/run.admin` includes `run.services.setIamPolicy`, which is critical for controlling public access.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
