Google Cloud Professional Cloud Architect — Question 38

During a high traffic portion of the day, one of your relational databases crashes, but the replica is never promoted to a master. You want to avoid this in the future.
What should you do?

Answer options

• A. Use a different database
• B. Choose larger instances for your database
• C. Create snapshots of your database more regularly
• D. Implement routinely scheduled failovers of your databases

Correct answer: D

Explanation

The correct answer is D because implementing routinely scheduled failovers ensures that in the event of a database crash, the replica can be quickly promoted to master, minimizing downtime. Options A and B do not address failover mechanisms, and while C is beneficial for backups, it does not prevent the issue of crashes impacting availability.
