Free Professional Cloud Database Engineer Exam Questions and Answers
Professional Cloud Database Engineer is one of the Google tests covered here. Three separate Google programmes are gathered here and they share little beyond the company name. Google Cloud certifications are proctored exams through Pearson OnVUE — 50 to 60 questions in about two hours, $99 at foundational level, $125 at associate and $200 at professional, valid two or three years by tier, with no pass mark published. The Skillshop credentials, meaning the Google Ads and Google Analytics ones, are the opposite: free, unproctored and self-administered, a 75-minute assessment needing 80% to pass and lapsing after a year. And the developer certification has been retired outright. Note too that AdWords became Google Ads on 24 July 2018, so any credential still carrying the older name has since been renamed.
The first 10 questions on this page are free to read, answers included — no account and no card. A plan opens the rest of the bank, the full timed practice test and your weak-topic reporting.
