OCP CBT Question 694

Please solve the following question.

You are planning a backup strategy for a large database. You want to take a backup that includes all data blocks that have changed since the last full backup (Level 0) or the last cumulative incremental backup (Level 1 Cumulative). Which RMAN backup type would you choose for this purpose?

RMAN supports various backup types to optimize backup time and storage. Incremental backups only back up blocks that have changed, saving time and space compared to full backups.

Incremental Level 0 Backup

Incremental Level 1 Cumulative Backup

Incremental Level 1 Differential Backup

Full Backup
