What makes the Professional Cloud Database Engineer exam hard
Professional Cloud Database Engineer is the exam for people who choose and run the databases behind Google Cloud applications, and the current guide added vector data and databases that support generative AI and LLM use cases to the design section, so AlloyDB and its AI features now appear alongside Cloud SQL, Spanner, Bigtable, Firestore and Memorystore. The questions are requirement driven: a workload, a consistency or availability need, a budget, and four databases that could all technically work.
Design is about 32% of the exam: capacity and usage planning, multi-regional versus regional versus zonal deployments, connectivity, key management and encryption, and evaluating managed versus self-managed and SQL versus NoSQL including vector databases. Managing a multi-database solution at about 25% covers IAM, backup and recovery with RTO and RPO, scaling, and cost and query optimisation.
Migration at about 23% covers zero and near-zero downtime strategies and choosing between Database Migration Service, Datastream and other tools. Deployment at about 20% covers provisioning highly available databases, testing HA and DR, and automated provisioning and monitoring.
