（E）DBFS must be used to bulk load data into a production database on the Database Machine.

（A）The DATA02 ASM diskgroup has better perfiormance because the DATA02 diskgroups was created first.

（B）The DATA01 diskgroup has better perfiormance because the DATA01 griddisks are created on interleaved cell disks.

（C）The DATA01 diskgroups has better perfiormance because the DATA01 griddisks were created first.

（D）The perfiormance ofi both diskgroups is balanced because they are created on interleaved griddisks.
