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
✓
Automated backups must be enabled, and write-ahead logging (WAL) must be active
Cloud SQL PITR requires automated backups and binary logging (for MySQL) or write-ahead logging (for PostgreSQL) to be enabled. Automated backups must be configured, and the instance must be using the appropriate database flags. For PostgreSQL, 'cloudsql.logical_decoding' and 'cloudsql.enable_pitr' are needed.

Automated backups and binary logging must be enabled
Why it's wrong here
Binary logging is for MySQL; PostgreSQL uses WAL.
- ✗
Point-in-time recovery is not supported for Cloud SQL PostgreSQL
Why it's wrong here
