NO.1 Which two statements are true about initialization parameters for Clustered ASM instances?
A. A change to ASM_DISKSTRING requires a restart of all ASM instances for the change to take effect.
B. The default value of INSTANT_TYPE is ASM.
C. ASM_POWER_LIMIT controls the number of RDBMS instances that can access a disk group while it
is being rebalanced.
D. The ASM_DISKGROUP parameter is optional.
E. The maximum value of ASM_POWER_LIMIT is 1024.
Answer: D,E

1z1-068 科目   1z1-068 受験期   
C: The default value of theASM_DISKGROUPS parameter is a NULL string. If the parameter value is
NULL or is not specified, then ASM does not mount any disk groups.
E: The ASM_POWER_LIMIT initialization parameter specifies the default power for disk rebalancing in
a disk group.
The range of values is 0 to 1024.

NO.2 Examine this output:
ASMCMD> volinfo - G ACFS -a
Diskgroup Name: ACFS
Volume Name: VOL1
Volume Device: /dev/asm/vol1-280
Size (MB): 2048
Resize Unit (MB): 32
Redundancy: MIRROR
Stripe Columns: 4
Stripe Width (K): 128
Usage: ACFS
Mountpath: /u01/app/grid/acfsmount
The ACFS disk group has 10 GB free space and the file system is currently mounted.
You execute this command to increase the volume size:
ASMCMD >volresize -G ACFS -s 3G VOL1
Which statement is true regarding the outcome?
A. It succeeds
B. It fails because the -f option is not specified.
C. It succeeds but the file system is automatically unmounted.
D. It fails because the file system must be unmounted before resizing.
E. Itfails because resizing a volume containing an ACFS file system must be performed using
Answer: E

If there is an Oracle ACFS file system on the volume, then you cannot resize the volume with the
volresize command.
You must use the acfsutil size command, which also resizes the volume and file system.

NO.3 Which three statements are true regarding ACFS snapshots in Oracle 12c ASM?
A. All ACFS snapshot operations for all filesystem are serialized clusterwide.
B. They can only be accessed whenthe file system is mounted.
C. You can create a snapshot from an existing snapshot.
D. They are contained in a directory on thesame volume as their parent file system.
E. They can be administered using ASMCM
F. They are always point-in-time copies of the parent file system.
Answer: A,B,C

1z1-068 開発   
All Oracle ACFS snapshot operations are serialized clusterwide in the kernel.
You chose to create a snapshot image on an existing snapshot group, select a snapshot group from
the existing snapshot group table (make sure you select a snapshot group that has not reached its
maximum limit of snapshot images).
Before you can access the files on a file system, you need to mount the file system.

NO.4 Which statement is true concerning the installation of an Oracle Grid Infrastructure 12c
patchset and its status during the installation?
A. When performing rolling patches, crsctl query crs softwareversion always displays the lowest
version of the software running anywhere in the cluster
B. They can be applied in-place.
C. Some grid infrastructure patchsets may not be installed in a rolling fashion.
D. When performing rolling patches, the VIPs for the node being patched are relocated to another
Answer: A

1z1-068 変更   
To check the software versions on a single node. Software version is the lastest version installed in on
an cluster.
You would use this option when you do the rolling upgrade.
$ crsctl query crs softwareversion [hostname]
