Limitations of this diagnostic: 30 questions cannot cover every exam objective with equal depth. Domains with fewer than three questions are labelled "Limited evidence" in your results and can never cause a readiness downgrade on their own. This is not an official exam, an accredited course, or a pass-rate prediction.
Technically validated: Completed September 7, 2026, against the current official Professional Cloud Developer exam guide (PDF) and current Google Cloud product documentation for Cloud Run, GKE/Kubernetes, Cloud Build, Artifact Registry, Binary Authorization, Spanner, Bigtable, Cloud SQL, Cloud Storage, Pub/Sub, Eventarc, Apigee, Cloud Service Mesh, Workload Identity Federation, Cloud Workstations, Cloud Code, Gemini Code Assist, Cloud Trace, and Error Reporting.
