Answer: Opt for a dual-region Cloud Storage bucket with turbo replication enabled.
The correct answer is **C. Opt for a dual-region Cloud Storage bucket with turbo replication enabled.** This approach ensures high availability and durability by redundantly storing data across two locations within a region. Turbo replication facilitates rapid data replication between these regions, significantly reducing the recovery point objective (RPO) in the event of a regional failure. This setup not only enhances resilience against regional outages but also guarantees data consistency and availability for applications relying on the stored data. **Why the other options are not ideal:** - **A. Implementing multi-regional Cloud Storage buckets** offers redundancy across multiple regions but may not achieve the same low RPO and high availability as a dual-region bucket with turbo replication. - **B. Using two regional Cloud Storage buckets and writing to both** lacks real-time replication, potentially leading to a higher RPO during failures. - **D. Scheduling daily data copies between two regional buckets** introduces replication delays, increasing the RPO and thus not effectively minimizing the impact of a regional failure.

You're designing an application that uses Cloud Storage for data storage and processing. The application's pipelines fetch raw data from one Cloud Storage bucket and save processed data in another. Your goal is to build a resilient architecture against Google Cloud regional failures, aiming for the lowest possible recovery point objective (RPO) without disrupting applications that access the stored data. What strategy should you implement to achieve this resilience and minimize RPO in Cloud Storage?
A
Implement multi-regional Cloud Storage buckets in your setup.
B
Use two regional Cloud Storage buckets and modify your application to write outputs to both.
C
Opt for a dual-region Cloud Storage bucket with turbo replication enabled.
D
Deploy two regional Cloud Storage buckets and schedule daily data copies from one to the other.
