Google Cloud Professional Cloud Architect — Question 224

Your company uses a custom-built application running on a Compute Engine virtual machine (VM). This application processes real-time sales data and writes it to a zonal Persistent Disk. A recent internal audit requires that you implement a backup and recovery plan to protect against zonal failures. Your company has a strict policy that all backup data must be retained for at least 90 days and stored in a separate project with limited access. You need to implement a fully automated backup solution that meets these requirements with minimal operational overhead. What should you do?

Answer options

• A. Write a script to create daily backups of the Persistent Disk. Copy the backups to a different zone and apply a label to each snapshot to indicate the deletion date.
• B. Use gcloud commands to create snapshots of the Persistent Disk. Store the snapshots in a regional Cloud Storage bucket and configure a lifecycle rule to delete objects older than 90 days.
• C. Create a snapshot schedule to automatically create Persistent Disk snapshots and use a script to move and store them in a multi-regional Cloud Storage bucket.
• D. Use the Backup and Disaster Recovery (DR) service to create a backup plan. Configure the backup plan to take daily snapshots and store them in a backup vault with a 90-day retention policy.

Correct answer: D

Explanation

The correct answer is D because the Backup and Disaster Recovery service is designed specifically for automated backup solutions that meet retention and access requirements. Options A, B, and C involve more manual processes or do not adequately meet the strict project separation and access control needed for compliance.
