Google Sample Question 10 of 27

You are designing the architecture of your application to store data in Cloud Storage. Your application consists of pipelines that read data from a Cloud Storage bucket that contains raw data, and write the data to a second bucket after processing. You want to design an architecture with Cloud Storage resources that are capable of being resilient if a Google Cloud regional failure occurs. You want to minimize the recovery point objective (RPO) if a failure occurs, with no impact on applications that use the stored data. What should you do?

A Adopt multi-regional Cloud Storage buckets in your architecture.
B Adopt two regional Cloud Storage buckets, and update your application to write the output on both buckets.
C Adopt a dual-region Cloud Storage bucket, and enable turbo replication in your architecture. ✓ Correct
D Adopt two regional Cloud Storage buckets, and create a daily task to copy from one bucket to the other.
🦉 Explanation by WiseOwl Tutor™ — not endorsed by Google

A. Is not correct because a multi regional bucket does not guarantee the minimum RPO for Cloud Storage. B. Is not correct because having two regional buckets would have an impact on the applications. C. Is correct because a bucket with Turbo replication guarantees a 15 min RPO. D. Is not correct because it has a RPO of up to 24 hours, and this would have an impact on the applications.
