    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.
