Which two statements are true regarding the backups performed?

You are managing an Oracle Database 11g database with the following backup strategy:1.On Sunday, an incremental level 0 tape backup is performed2.Monday through Saturday, a cumulative incremental level 1 tape backup is performedWhich two statements are true regarding the backups performed? (Choose two.)backup-level DescriptionThe backup-level placeholder specifies the level of a backup created with the backup command.Syntax backup-level::= full | incr_level | incr | offsite incr_level::=1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9Semantics fullSpecifies that Oracle Secure Backup should back up all files defined in a dataset regardless of when they were last backed up. This option is equivalent to level 0.This is the default value. incr_levelSpecifies an incremental level from 1 to 9 and backs up only those files that have changed since the last backup at a lower level. incrSpecifies that Oracle Secure Backup should back up any file that has been modified since the last incremental backup at the same level or lower. The incr option is equivalent to level 10. This level is platform dependent and is incompatible with some client operating systems such as the Netapp filer’s Data ONTAP. offsiteEquivalent to a full (level 0) backup except that Oracle Secure Backup keeps a record of this backup in such a way that it does not affect the full or incremental backup schedule. This option is useful when you want to create a backup image for offsite storage without disturbing your schedule of incremental backups.
