PCDE Practice Question: Manage a solution that can span multiple database technologies
A company is running a production Cloud SQL for PostgreSQL instance and wants to implement point-in-time recovery (PITR) with a 7-day retention window. They also need to ensure that automated backups are taken daily. Which two configurations must be enabled? (Choose TWO.)
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
✓
Set the database flag 'archive_mode' to 'on' for WAL archiving
PITR requires WAL archiving, which is enabled by setting the 'archive_mode' to 'on' (or 'always') in the database flags. Automated backups are scheduled via the backup configuration in Cloud SQL. The retention period for PITR is set separately under backup settings.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Set the database flag 'archive_mode' to 'on' for WAL archiving
Why this is correct
WAL archiving is required for PITR in PostgreSQL.
- ✗
Enable binary logging by setting 'log_bin' flag
Why it's wrong here
Binary logging is for MySQL PITR, not PostgreSQL.
- ✓
Configure automated backups via Cloud SQL backup settings
Why this is correct
Automated backups are needed for PITR, as they provide the base backup for recovery.
- ✗
Create a cross-region backup replica
Why it's wrong here
Cross-region replicas are for DR, not required for PITR.
- ✗
Set the backup retention to 7 days using gcloud sql instances patch --backup-start-time
Why it's wrong here
Backup retention is set in the backup configuration, not via --backup-start-time.
