1z0-060: Upgrade to Oracle Database 12c Rman Practice Questions

You performed an incremental level 0 backup of a database: RMAN > BACKUP INCREMENTAL LEVEL 0 DATABASE; To enable block change tracking after the incremental level 0 backup, you issued this command: SQL > ALTER DATABASE ENABLE BLOCK CHANGE TRACKING USING FILE ‘ /mydir/rman_change_track.f’; To perform an incremental level 1 cumulative backup, you issued this command: RMAN> BACKUP INCREMENTAL LEVEL 1 CUMULATIVE DATABASE; Which three statements are true?

Select 3 answers.

• AA. Backup change tracking will sometimes reduce I/O performed during cumulative incremental backups.
• BB. The change tracking file must always be backed up when you perform a full database backup.
• CC. Block change tracking will always reduce I/O performed during cumulative incremental backups.
• DD. More than one database block may be read by an incremental backup for a change made to a single block.
• EE. The incremental level 1 backup that immediately follows the enabling of block change tracking will not read the change tracking file to discover changed blocks.

Your multitenant container database (CDB) is running in ARCHIVELOG mode. You connect to the CDB RMAN. Examine the following command and its output: You execute the following command: RMAN > BACKUP DATABASE PLUS ARCHIVELOG; Which data files will be backed up?

• AA. Data files that belong to only the root container
• BB. Data files that belong to the root container and all the pluggable databases (PDBs)
• CC. Data files that belong to only the root container and PDB$SEED
• DD. Data files that belong to the root container and all the PDBs excluding PDB$SEED
