GCP Database Engineer study guide
GCP Database Engineer · Work through your exam, one topic at a time.
The Professional Cloud Database Engineer is a Google Cloud certification aimed at database professionals who design, build, manage, and troubleshoot the cloud databases that applications rely on for storing and retrieving data. Google describes the target candidate as someone with roughly two years of Google Cloud experience and five years of overall database and IT experience, comfortable turning business and technical requirements into scalable, cost-effective database solutions. The exam is delivered in English and Japanese as 50–60 multiple-choice questions over two hours, costs $200 plus tax where applicable, has no prerequisites, and stays valid for two years. It is scored against four equally weighted domains: designing scalable and highly available cloud database solutions; managing a solution spanning multiple database solutions; migrating data solutions; and deploying scalable and highly available databases in Google Cloud. The GCP Database Engineer study guide has 4 sections and about 1,639 words.
01Design scalable and highly available cloud database solutions
This domain tests whether you can select the right Google Cloud database for a workload and design it to survive zone or region failure while scaling reads and writes. The exam favors concrete trade-offs: consistency model, write throughput, latency, SLA, and operational burden.
432 words, about 2 min02Manage a solution that can span multiple database solutions
This domain tests operating a heterogeneous data estate: moving data between databases, keeping schemas and identity consistent, monitoring across engines, and governing backups and access. The exam expects you to know which service owns which job rather than forcing one database to do everything.
420 words, about 2 min03Migrate data solutions
This domain tests planning and executing migrations with minimal downtime and verified correctness. The exam distinguishes homogeneous migrations, heterogeneous conversions, online versus offline transfer, and the tools Google Cloud provides for each.
395 words, about 2 min04Deploy scalable and highly available databases in Google Cloud
This domain tests turning an architecture into a working deployment: network placement, HA settings, backups, maintenance, observability, and repeatable infrastructure. The exam expects concrete configuration choices, not just service selection.
