Which two commands will create a 500 MB volume called TESTVOL in the ACFSDG ACFS diskgroup by storing only one copy of the volume file extents in the diskgroup

From a command line, you can create an ASM volume with the same properties by using either
SQL or ASMCMD. Which two commands will create a 500 MB volume called TESTVOL in the
ACFSDG ACFS diskgroup by storing only one copy of the volume file extents in the diskgroup

A.
SQL> alter diskgroup ACFSDG add volume TESTVOL size 500M unprotected;

B.
ASMCMD> volcreate -G ASMFS -s 500M

C.
SQL> alter diskgroup ACFS add volume TESTVOL size 500M;

D.
ASMCMD> volcreate -G ACFSDG -s 500M –redundancy unprotected TESTVOL

E.
SQL> create volume TESTVOL diskgroup ACFSDG size 500M unprotected;

Explanation:
The ALTER DISKGROUP VOLUMESQL statements enable you to manage Oracle
ADVM volumes, including the functionality to add, modify, resize, disable, enable, and drop
volumes.
You can create an Oracle ASM Dynamic Volume Manager (Oracle ADVM) volume in a disk group.
The volume device associated with the dynamic volume can then be used to host an Oracle ACFS
file system.
If the volume is hosting an Oracle ACFS file system, then you cannot resize that volume with the
SQL ALTER DISKGROUP statement. Instead you must use the acfsutil size command.
volcreate
Creates an Oracle ADVM volume in the specified disk group.
Syntax and Description
volcreate -G diskgroup -s size [ –column number ] [ –width stripe_width ]
[–redundancy {high|mirror|unprotected} ]
Redundancy of the Oracle ADVM volume which can be specified for normal redundancy disk
groups. The range of values is as follows: unprotected for non-mirrored redundancy, mirror for
double-mirrored redundancy, or high for triple-mirrored redundancy. If redundancy is not specified,
the setting defaults to the redundancy level of the disk group.
