PCDE Practice Question: Deploy scalable and highly available databases in Google Cloud

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
✓
Enable automated backups with retention set to 30 days and create on-demand backups daily to cover the 365-day retention
Cloud SQL supports automated backups and point-in-time recovery (PITR) using binary logs. The maximum automated backup count is 365, and you can set the transaction log retention for PITR up to 35 days. For 365-day retention, you need to use on-demand backups (snapshots) which can be retained indefinitely. For PITR within 30 days, enable automated backups and binary logging with a log retention of 30 days.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use export to Cloud Storage daily and store exports for 365 days
Why it's wrong here
Exports are not backups for PITR and would not allow point-in-time recovery within 30 days.
- ✗
Enable automated backups with retention set to 365 days and enable binary logging for PITR
Why it's wrong here
Automated backups can be retained up to 365 days, but PITR transaction log retention max is 35 days. 30 days is fine, but 365-day backup retention is possible with automated backups.
- ✗
Enable automated backups with retention set to 365 days and set transaction log retention to 365 days
Why it's wrong here
Transaction log retention maximum is 35 days, not 365.
- ✓
Enable automated backups with retention set to 30 days and create on-demand backups daily to cover the 365-day retention
Why this is correct
On-demand backups (snapshots) can be retained indefinitely. Automated backups for PITR can be set to 30 days to meet PITR requirement, while on-demand backups meet long-term retention.
