How hard is the Professional Cloud Developer exam? +
Developers expecting a coding test are usually surprised. The largest section, designing scalable, secure and reliable cloud-native applications, is about 32% of the exam and is mostly architecture and trade-offs. Runtime choice between Cloud Run, GKE and Compute Engine comes up constantly. Security tooling well beyond basic IAM - Secret Manager, Cloud KMS, Workload Identity Federation, Binary Authorization - is also in scope.
What is the Professional Cloud Developer exam format? +
The exam is 2 hours with 50-60 multiple-choice questions, in English or Japanese. You can take it online with remote proctoring or at a Pearson VUE testing center. There are no formal prerequisites. The registration fee is $200, plus tax where applicable. Expect long scenario questions where several answers are technically possible and only one matches every stated requirement.
What changed in the current Professional Cloud Developer exam guide? +
The current guide names AI tooling explicitly, including Gemini Cloud Assist, AI coding assistants and MCP servers. Prep built on the older outline will not cover how Google now expects developers to use these tools. Download the current exam guide and check every section against your course before relying on older practice questions.
How long is it valid and how do I renew? +
The certification is valid for two years. Google offers renewal through designated courses or skill badges on Google Skills, completed within the last year of the active period, or you can retake the standard exam. Check the certification page for any renewal exam option, since renewal formats differ by certification.
What experience does the Professional Cloud Developer exam assume? +
Google recommends 3+ years of industry experience, including at least 1 year designing and managing solutions on Google Cloud. If you know one runtime well, plan time on the others - most candidates need 6-10 weeks. Build and deploy a small app on Cloud Run and GKE, wire up Secret Manager and Cloud Build, and practice observability with Cloud Logging and Trace.
What is the retake policy? +
If you fail, you wait 14 days before the next attempt. A second failure means a 60-day wait, and a third means waiting a year. Each attempt costs the full registration fee. Use your result to decide where to focus, and lean on scenario practice rather than re-reading documentation.
