Topic 1 Question 70
You work for a global financial services company that trades stocks 24/7. You have a Cloud SGL for PostgreSQL user database. You need to identify a solution that ensures that the database is continuously operational, minimizes downtime, and will not lose any data in the event of a zonal outage. What should you do?
Continuously back up the Cloud SGL instance to Cloud Storage. Create a Compute Engine instance with PostgreSCL in a different region. Restore the backup in the Compute Engine instance if a failure occurs.
Create a read replica in another region. Promote the replica to primary if a failure occurs.
Configure and create a high-availability Cloud SQL instance with the primary instance in zone A and a secondary instance in any zone other than zone A.
Create a read replica in the same region but in a different zone.

- 正解だと思う選択肢: C
The best option is C. HA Cloud SQL. Option C is best: HA is built for continuous ops and zonal failure protection. Option A is incorrect: Backup/restore = downtime. Option B is incorrect: Replica less direct for zonal failover. Option D is incorrect: Read replica no auto-failover for primary. Option C = HA for best uptime.
