Which statements are true regarding extent management and allocation units in the ASM disk group？（）

A.  The au_size disk group attribute determines the size of allocation units in the disk group.

B.  The allocation unit size may vary but the extent size is fixed.

C.  The allocation unit size and extent size are fixed for all the disks in a disk group and cannot be changed.

D.  Extent management is completely automated.

A database is stored in an Automatic Storage Management (ASM) disk group, disk group, DGROUP1 with SQL:There is enough free space in the disk group for mirroring to be done.What happens if the CONTROLLER1 failure group becomes unavailable due to error of for maintenance？（）

A. Transactions and queries accessing database objects contained in any tablespace stored in DGROUP1 will fall.

B. Mirroring of allocation units will be done to ASM disks in the CONTROLLER2 failure group until the CONTROLLER1 for failure group is brought back online.

C. The data in the CONTROLLER1 failure group is copied to the controller2 failure group and rebalancing is initiated.

D. ASM does not mirror any data until the controller failure group is brought back online, and newly allocated primary allocation units (AU) are stored in the controller2 failure group, without mirroring.

E. Transactions accessing database objects contained in any tablespace stored in DGROUP1 will fail but queries will succeed.

A. when ASM disk goes offline

B. when one or more ASM files are dropped

C. when some disks in a disk group are offline

D. when some disks in a failure group for a disk group are rebalancing

A. Failed disks are taken offline immediately but are not dropped.

B. Disk data is never lost.

C. By default, the failed disk is not dropped from the disk group ever, protecting you from loss of that disk.

D. The failed disk is automatically reformatted and then resynchronized to speed up the recovery process.

E. Hot spare disks are automatically configured and added to the disk group.

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.

erver.All databases of all versions use Automatic Storage Management (ASM).Which three statements are true about the ASM disk group compatibility attributes that are set for a disk group？（）

A. The ASM compatibility attribute controls the format of the disk group metadata.

B. RDBMS compatibility together with the database version determines whether a database Instance can mount the ASM disk group.

C. The RDBMS compatibility setting allows only databases set to the same version as the compatibility value, to mount the ASM disk group.

D. The ASM compatibility attribute determines some of the ASM features that may be used by the Oracle disk group.

E. The ADVM compatibility attribute determines the ACFS features that may be used by the Oracle 10g database.

ization parameter is set to 11.1.0. In the ASM instance, the COMPATIBLE.RDBMS attribute for the disk group is set to 10.2 and the COMPATIBLE.ASM attribute is set to 11.1.Which two statements are true in this scenario for the features enabled for ASM？ （）

A. The ASM-preferred mirror read feature is enabled.

B. The ASM supports variable sizes for extents of 1, 8, and 64 allocation units.

C. The ASM disk is dropped immediately from a disk group when it becomes unavailable.

D. The RDBMS always reads the primary copy of a mirrored extent of the ASM disk group.
