A
Implement BigQuery with no region selected for storage or processing.
B
Implement Cloud Spanner with the leader in North America and read-only replicas in Asia and Europe.
C
Implement Cloud SQL for PostgreSQL with the master in North America and read replicas in Asia and Europe.
D
Implement Cloud Bigtable with the primary cluster in North America and secondary clusters in Asia and Europe.
Explanation:
Explanation
Option B (Cloud Spanner) is the correct answer because:
- Global Consistency: Cloud Spanner provides strong global consistency across regions, which is essential for financial data where consistency is critical
- Multi-Region Deployment: Cloud Spanner supports leader configuration in one region (North America) with read-only replicas in other regions (Asia and Europe), providing low-latency access globally
- ACID Compliance: As a relational database, Cloud Spanner ensures ACID transactions across regions
- High Availability: Automatic failover and global replication ensure high availability
Why other options are incorrect:
- Option A (BigQuery): BigQuery is primarily an analytical data warehouse, not designed for transactional workloads with global consistency requirements
- Option C (Cloud SQL): While Cloud SQL supports read replicas, it doesn't provide the same level of global consistency and automatic failover as Cloud Spanner for multi-region deployments
- Option D (Cloud Bigtable): Cloud Bigtable is a NoSQL database optimized for high-throughput workloads but doesn't provide the same transactional consistency guarantees as Cloud Spanner
For financial data requiring global consistency with low-latency access across North America, Asia, and Europe, Cloud Spanner is the most appropriate choice.
