What this test covers
One concept per question, across the topics Professional Cloud Database Engineer draws on.
- Connection pooling decouples application concurrency from database connection count
- Continuous replication minimises the cutover window
- Sequential row keys create hotspots because Bigtable distributes contiguous key ranges
- RPO is data loss tolerance; RTO is downtime tolerance
- High availability provides automatic failover; read replicas do not
- Spanner is the option combining horizontal scale with strong global consistency
These questions are written by GCP Prep to test understanding of publicly documented concepts. They are not real exam questions and are not a prediction of what any exam contains.
