(Choose two.)

Prerequisites
Execute LIST only at the RMAN prompt. Either of the following conditions must be met:
– RMAN must be connected to a target database. If RMAN is not connected to a recovery catalog, and if
you are not executing the LIST FAILURE command, then the target database must be mounted or
open. If RMAN is connected to a recovery catalog, then the target database instance must be started.
– RMAN must be connected to a recovery catalog and SET DBID must have been run.
Usage Notes
With the exception of LIST FAILURE, the LIST command displays the backups and copies against which you can run CROSSCHECK and DELETE commands. The LIST FAILURE command displays failures against which you can run the ADVISE FAILURE and REPAIR FAILURE commands.
"RMAN Backups in a Data Guard Environment" explains how RMAN handles backups in a Data Guard environment. In general, RMAN considers tape backups created on one database in the environment as accessible to all databases in the environment, whereas disk backups are accessible only to the database that created them. In a Data Guard environment, LIST displays those files that are accessible to the connected target database.
RMAN prints the LIST output to either standard output or the message log, but not to both at the same time.

The LIST command displays information about backupsets and image copies in the repository and can also store the contents of scripts stored in the repository catalog.
Another variation on the LIST command is LIST FAILURE, which displays database failures; LIST FAILURE, ADVISE FAILURE, and REPAIR FAILURE
