Multiple RMAN sessions are connected to the database instance.Examine the following output when backup commands are running in server sessions:What could have helped you to correlate server sessions with channels?()A. Implement RMAN multiplexingB. Set the DEBUG ON in the RMAN scriptC. Specify the command ID in the RMAN scriptD. Use a tag with the RMAN BACKUP command

View the Exhibit to examine the error during the database startup.You open an RMAN session for the database instance. To repair the failure, you executed the following as the first command in the RMAN session:RMAN REPAIR FAILURE;Which statement describes the consequence of the command?()A. The command performs the recovery and closes the failures.B. The command only displays the advice and the RMAN script required for repair.C. The command produces an error because the ADVISE FAILURE command has not been executed before the REPAIR FAILURE command.D. The command executes the RMAN script to repair the failure and removes the entry from the Automatic Diagnostic Repository (ADR).

You are administering a database stored in Automatic Storage Management (ASM). You use RMAN to back up the database and the MD_BACKUP command to back up the ASM metadata regularly. You lost an ASM disk group DG1 due to hardware failure.In which three ways can you re-create the lost disk group and restore the data?()A. Use the MD_RESTORE command to restore metadata for an existing disk group by passing the existing disk group name as an input parameter and use RMAN to restore the data.B. Use the MKDG command to restore the disk group with the same configuration as the backed-up disk group and data on the disk group.C. Use the MD_RESTORE command to restore the disk group with the changed disk group specification, failure group specification, name, and other attributes and use RMAN to restore the data.D. Use the MKDG command to restore the disk group with the same configuration as the backed-up disk group name and same set of disks and failure group configuration, and use RMAN to restore the data.E. Use the MD_RESTORE command to restore both the metadata and data for the failed disk group.F. Use the MKDG command to add a new disk group DG1 with the same or different specifications for failure group and other attributes and use RMAN to restore the data.
