Explanation:
This sequence provides correct steps to do for recovery. Incorrect Answer:
1: You need to use SET NEW NAME command to rename files to be restored on a new disk.
3: The SET NEW NAME, not RESTORE NEW NAME, command should be issued before restoring data files.
4: The SWITCH command should be used after RESTORE, before RECOVER command. It specifies that a data file copy is now the current data file, that is, the data file pointed to by the control file. A switch is equivalent to using the ALTER DATABASE RENAME FILE statement: Oracle renames the files in the control file but does not actually rename them on the operating system. Note that this command deletes the records for the data file copy from the recovery catalog and updates the control file records to status DELETED.
