Correct Answer: E
Explanation/Reference: Explanation: Backing Up a Database in NOARCHIVELOG Mode If a database runs in NOARCHIVELOG mode, then the only valid database backup is a consistent backup. For the backup to be consistent, the database must be mounted after a consistent shutdown. No recovery is required after restoring the backup. To make a consistent database backup: 1. Start RMAN and connect to a target database. 2. Shut down the database consistently and then mount it. For example, enter the following commands to guarantee that the database is in a consistent state for a backup: RMAN> SHUTDOWN IMMEDIATE; RMAN> STARTUP FORCE DBA; RMAN> SHUTDOWN IMMEDIATE; RMAN> STARTUP MOUNT; 3. Run the BACKUP DATABASE command. For example, enter the following command at the RMAN prompt to back up the database to the default backup device: RMAN> BACKUP DATABASE; The following variation of the command creates image copy backups of all data files in the database: RMAN> BACKUP AS COPY DATABASE; 4. Open the database and resume normal operations. The following command opens the database: RMAN> ALTER DATABASE OPEN;
