Correct : D
To ensure resilience and minimize the recovery point objective (RPO) with no impact on applications, using a dual-region bucket with turbo replication is the best approach. Here's why option D is the best choice:
Dual-Region Buckets:
Dual-region buckets store data redundantly across two distinct geographic regions, providing high availability and durability.
This setup ensures that data remains available even if one region experiences a failure.
Turbo Replication:
Turbo replication ensures that data is replicated between the two regions within 15 minutes, aligning with the requirement to minimize the recovery point objective (RPO).
This feature provides near real-time replication, significantly reducing the risk of data loss.
No Impact on Applications:
Applications continue to access the dual-region bucket without any changes, ensuring seamless operation even during a regional failure.
The dual-region setup transparently handles failover, providing uninterrupted access to data.
Steps to Implement:
Create a Dual-Region Bucket:
Create a dual-region Cloud Storage bucket in the Google Cloud Console, selecting appropriate regions (e.g., us-central1 and us-east1).
Enable Turbo Replication:
Enable turbo replication to ensure rapid data replication between the selected regions.
Configure Applications:
Ensure that applications read and write to the dual-region bucket, benefiting from its high availability and durability.
Test Failover:
Simulate a regional failure to verify that the dual-region bucket and turbo replication meet the required RPO and ensure data resilience.
