Domain 5: Managing Implementation and Ensuring Solution and Operations Reliability — GCP PCA Practice Question 35

How to approach this question

An RPO of 0 requires synchronous replication across regions. Only Spanner does this natively.

Full Answer

B.Active-Active multi-region deployment with Cloud Spanner.✓ Correct

Active-Active multi-region deployment with Cloud Spanner.

An RPO of 0 means absolutely no data loss is acceptable in the event of a regional failure. This requires synchronous cross-region replication. Cloud Spanner is the only GCP database that provides this natively. Combined with an Active-Active compute architecture (using Global Load Balancing), the RTO will be near-zero, easily meeting the 5-minute requirement.

Common mistakes

Choosing Cloud SQL (A). Cross-region replicas in Cloud SQL are asynchronous, meaning a sudden regional failure will result in the loss of in-flight transactions.

You are designing a disaster recovery strategy for a mission-critical application. The business requires an RTO (Recovery Time Objective) of 5 minutes and an RPO (Recovery Point Objective) of 0 (zero data loss). Which architecture meets these requirements?
