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.
Refer to the exhibit. A DevOps engineer assigned this custom role to a service account used in Cloud Build. The pipeline fails when trying to access a secret stored in Secret Manager. Which permission is missing?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
secretmanager.versions.access
The custom role assigned to the Cloud Build service account lacks the `secretmanager.versions.access` permission, which is required to access the payload of a secret version in Secret Manager. Without this permission, any attempt to read the secret value during a build step will fail with a permission denied error, even if the service account has other roles on the project.
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.
✗
cloudbuild.builds.update
Why it's wrong here
Not needed to access secrets; the pipeline already runs builds.
✗
run.services.get
Why it's wrong here
Not required for secret access; already has run.services.update.
✓
secretmanager.versions.access
Why this is correct
Required to access the latest version of a secret.

✗
iam.serviceAccounts.actAs
Why it's wrong here
Needed for deploying to Cloud Run, but not for secret access.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the distinction between permissions that manage resources (e.g., `get`, `update`) and permissions that access data (e.g., `access`), leading candidates to pick a generic read permission like `get` instead of the specific `access` permission required for secret payloads.
Detailed technical explanation
How to think about this question
Secret Manager uses a two-level resource hierarchy: secrets (containers) and secret versions (the actual data). The `secretmanager.versions.access` permission is checked at the secret version level, and IAM conditions can further restrict access based on attributes like resource name or timestamp. In Cloud Build, the default compute engine service account or a user-specified service account must have this permission on the secret or the project to read secret values via the `gcloud secrets versions access` command or the Secret Manager API.
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.
