GCP Associate Cloud Engineer Practice Question

A SaaS provider runs a transactional application on a single-region Cloud Spanner instance in us-central1. Rapid growth in EMEA and APAC now requires the database to survive a regional outage and continue to accept strongly consistent writes with no manual failover. Availability must increase from four nines (99.99 %) to five nines (99.999 %) while keeping day-to-day operations simple. What should you do?

  • Export the data to BigQuery and place it in a multi-region US dataset to handle global traffic.

  • Create a new Cloud Spanner instance that uses the nam-eur-asia1 multi-region configuration and migrate the database to it.

  • Change the instance to use a dual-region configuration with us-central1 as the write region and us-east1 as the witness region.

  • Add cross-region read-only replicas in europe-west1 and asia-southeast1 to the existing single-region instance.
