What is the passing score?

Google does not publish it. The official FAQ states that Google Cloud exams are designed only to determine whether a candidate meets the minimum passing standard, and that only a pass or fail result is provided. Figures such as '70% to pass' are not official.

Which case studies will appear?

The official exam guide publishes four: Altostrat Media, Cymbal Retail, EHR Healthcare and KnightMotives Automotive. Two of them are used on the actual exam, and case study questions account for 20 to 30 percent of the total. You can read all four in advance.

If I fail, can I retake it right away?

You can retake it after 14 days. A second failure means waiting 60 days and a third means 365 days, and Associate and Professional level exams are limited to four attempts in two years. Attempts count regardless of the exam language or the delivery method (online or test center).

Does renewal mean sitting this exam again?

No. Renewal is a separate one-hour, 25-question exam costing USD 100. It centers on a single case study built around generative AI solutions, which accounts for 90 to 100 percent of the questions. You need a valid certification and to be inside the renewal window, which opens 60 days before expiry for Professional level certifications.

Can I take it in Japanese?

Yes. The two languages officially offered are English and Japanese.

Professional Cloud Architect (Google Cloud certification)

Professional Cloud Architect is a Professional-level certification from Google Cloud. It asks you to design an architecture from business and technical requirements, and then covers building and provisioning the infrastructure, security and compliance, optimizing technical and business processes, managing the implementation, and operational excellence. The exam runs two hours and consists of 50 to 60 multiple choice and multiple select questions. It costs USD 200 and can be taken in English or Japanese. Its defining feature is the case studies: four fictional companies are published in advance, two of them appear on any given exam, and case study questions make up 20 to 30 percent of the paper. Google does not publish a passing score, and results are returned as pass or fail only. The certification is valid for two years. Renewal is handled through a separate, shorter exam rather than sitting the full test again. Because the questions start from requirements rather than from individual services, preparing for it is closer to practicing architectural decisions than to memorizing product features.

Who takes it

Cloud architects who decide how systems are structured on Google Cloud
Infrastructure engineers designing migrations to Google Cloud from on-premises or another cloud
Solution architects at systems integrators who handle everything from requirements to a proposed architecture
Lead engineers responsible for technical decisions on multi-cloud or hybrid setups
SREs and IT staff responsible for operational design and cost optimization on Google Cloud

What it lets you do

Because the questions center on case studies, preparation trains you to decide on an architecture from requirements rather than to recall individual services
You learn to articulate design decisions against the Google Cloud Well-Architected Framework (operational excellence, security, reliability, performance optimization, cost optimization and sustainability)
The exam is available in Japanese, so the same content as the English version can be read in your own language
If you do not pass, a score report with a breakdown by section is available under Exam History in the Candidate Portal, which helps pinpoint weak areas
The two-year validity and the renewal exam build in a cycle for keeping up with changes on the Google Cloud side
