You are using Recovery Manager (RMAN) with a recovery catalog to back up your production database. Thebackups and the archived redo log files are copied to a tape drive on a daily basis.Because of media failure,you lost your production database completely along with the recovery catalog database.You want to recover the target database and make it functional. You consider performing the following steps to accomplish the task:1) Restore an autobackup of the server parameter file.2) Restore the control file3) Start the target database instance4) Mount the database5) Restore the data files6) Open the database with RESETLOGS option7) Recover the data files8) Set DBID for the target databaseWhich option illustrates the correct sequence that you must use？（） A.8，1，3，2，4，5，7，6 B.1，8，3，4，2，5，7，6 C.1，3，4，2，8，5，6，7 D.1，3，2，4，6，5，7，8

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.
