    D

     A new disk group called tdgroupA will be added with two failover groups and the /devices/A1 disk will be ignored for the new disk group because it is a member of an existing disk group tdgroup1.

    A

    The command drops the file +tdgroupA·231.45678.

    B

    The command physically relocates the file to +tdgroupA/data and renames the file to datafile.dbf.

    C

    The command creates a copy of the +tdgroupA·231.45678 file and places it in +tdgroupA/data after renaming the file to datafile.dbf.

    D

    The command creates an alias， datafile.dbf， and places it in +tdgroupA/data and does not remove the +tdgroupA·231.45678 file.

    E

    The command creates a file， datafile.dbf， in +tdgroupA/data and removes the references for +tdgroupA·231.45678 from the data dictionary views.
