Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Enable automated backups and configure a retention of 1-7 days; PITR uses WAL archiving automatically.
Why this is correct
In Cloud SQL for PostgreSQL, PITR is enabled by automated backups with a retention of 1-7 days; WAL archiving is handled automatically.
- ✗
Enable binary logging and set a backup retention of 1-7 days.
Why it's wrong here
Binary logging is for MySQL, not PostgreSQL.
- ✗
Set up cross-region backup replicas and configure a retention of 1-7 days.
Why it's wrong here
Cross-region replicas are for disaster recovery, not PITR.
- ✗
Enable PITR by setting the 'pitr_enabled' flag to true in the database flags.
Why it's wrong here
There is no such flag; PITR is configured via backup retention.
