Preparing for the Google Cloud Professional Cloud Database Engineer Certification?
This course provides 2025-aligned practice exams that accurately reflect the complexity, depth, and domain coverage of the official Google exam.

These practice tests help you master the full Google Cloud database ecosystem:

• Deploying, scaling & managing Cloud SQL, AlloyDB, Spanner, Bigtable
• Designing high-availability topologies across zones, regions, and multi-regions
• Migration strategies with near-zero downtime, replication & rollback
• SQL vs NoSQL use cases for structured, semi-structured, vector, and unstructured data
• Designing secure database connectivity, IAM policies, encryption, VPC setup
• Performance tuning, slow query debugging, index strategies, and cost optimization
• Monitoring workloads via Cloud Monitoring, Logging, and query insights
• Backup, recovery, PITR, retention, HA & DR testing
• Automating database tasks, scheduling jobs, managing upgrades
• Multi-database architecture, federation, and hybrid deployments
• Database strategies for LLMs and generative AI workloads

Each question comes with a clear explanation that teaches both the correct answer and the logic behind rejecting other options.

This course prepares you for real-world Google Cloud database responsibilities and helps you pass on your first attempt.
