Actual exam question for Google's Professional-Cloud-Database-Engineer exam
Question #: 2
Topic #: 8
You are planning connectivity for a global retail analytics service that runs in multiple Google Cloud regions and must reach a Cloud Spanner database with very low latency, strong security, and high reliability. Which connection approach should the application adopt to satisfy these requirements?

Suggested Answer: B Vote an answer

A multi-region Cloud Spanner instance provides globally distributed replicas with strong consistency and very high availability, which aligns with the needs of a global application. The client libraries use efficient gRPC connections and integrate with IAM for strong authentication and authorization. Connection pooling minimizes session and channel creation overhead, which improves throughput and tail latency while increasing reliability through automatic retries and health checks.
