DBS-C01 Deployment and Migration Practice Question
A company is deploying a new MySQL database on Amazon RDS. They need to ensure that the database is automatically backed up daily and retained for 30 days. Which TWO configurations should be set? (Choose 2)
⚠ Common exam trap
Candidates often confuse the backup window (Option C) or Multi-AZ (Option D) as being required for backup retention, when in fact only enabling automated backups and setting the retention period are necessary; the backup window is optional and Multi-AZ is unrelated to backup retention.

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 backup retention period to 30 days.
Setting the backup retention period to 30 days ensures that automated backups are retained for the required duration. Option B is correct because automated backups must be enabled for the retention period to take effect; without enabling automated backups, no automatic daily backups occur. Together, these two settings satisfy the requirement for daily automated backups retained for 30 days.
