Google PCA Practice Question: Managing Implementation and Ensuring Solution and Operations Reliability
A company is designing a disaster recovery (DR) plan for their Cloud SQL for PostgreSQL instance. They need to recover the database to a specific point in time within the last 7 days, with a Recovery Point Objective (RPO) of less than 1 hour. Which feature should they use?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Point-in-time recovery (PITR)
Cloud SQL automated backups combined with point-in-time recovery (PITR) allow recovery to any point in time within the backup retention period (default 7 days) by using transaction logs. PITR enables RPO of less than 1 hour because it uses write-ahead logs.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Exporting the database daily to Cloud Storage
Why it's wrong here
Daily exports provide an RPO of 24 hours, not <1 hour.
- ✓
Point-in-time recovery (PITR)
Why this is correct
PITR uses transaction logs to restore to any second within the retention period, meeting the <1 hour RPO.
- ✗
Failover replica
Why it's wrong here
A failover replica provides high availability, not DR. It does not allow point-in-time recovery.
- ✗
Automated backups only
Why it's wrong here
Automated backups alone only allow recovery to the backup time (typically daily), not to any point in time, so RPO is >1 hour.
