DBS-C01 Database Security Practice Question
A developer accidentally deleted an RDS database. Which action will allow the database to be restored with the least data loss?
⚠ Common exam trap
A common mix-up: candidates assume manual snapshots are the safest recovery method, but they lack the transaction log replay capability of PITR, leading to greater data loss than using automated backups with point-in-time recovery.

Correct answer & explanation
✓
Restore from the latest automated backup using point-in-time recovery.
Point-in-time recovery (PITR) allows you to restore an RDS DB instance to any second within the automated backup retention period, typically up to the last five minutes. This minimizes data loss because it replays transaction logs from the latest automated backup to the specified time, recovering changes made right up to the deletion moment. Automated backups are enabled by default with a 7-day retention, making PITR the most granular recovery option.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Restore from the latest automated backup using point-in-time recovery.
Why this is correct
Automated backups allow restoration to any point within the retention period, minimizing data loss.
- ✗
Use the 'Recycle Bin' feature to recover the RDS instance.
Why it's wrong here
RDS does not have a Recycle Bin.
- ✗
Restore from the latest manual snapshot.
Why it's wrong here
A manual snapshot may not exist or may be outdated.
