Google PCA Practice Question: Managing and Provisioning a Solution Infrastructure
An engineer is troubleshooting a Cloud Build trigger that fails with the error 'PERMISSION_DENIED: Cloud Build service account does not have permission to access Artifact Registry'. The build needs to push a Docker image to Artifact Registry. What is the correct IAM role to assign to the Cloud Build service account?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
roles/artifactregistry.writer
The Cloud Build service account (usually project-number@cloudbuild.gserviceaccount.com) needs the Artifact Registry Writer role to push images. Editor role is too broad; Viewer is read-only; Storage Object Admin is for Cloud Storage, not Artifact Registry.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
roles/artifactregistry.writer
Why this is correct
This role allows uploading artifacts to Artifact Registry, which includes pushing Docker images.
- ✗
roles/artifactregistry.viewer
Why it's wrong here
Viewer only allows reading, not writing.
- ✗
roles/editor
Why it's wrong here
Editor includes many permissions but is too broad and not required; specific roles are preferred.

roles/storage.objectAdmin
Why it's wrong here
Artifact Registry is not Cloud Storage; this role does not grant Artifact Registry permissions.
