Examine the output of this command:
ASMCMD> volinfo -G ACFS -a
Diskgroup Name: ACFS
Volume Name: VOL1
Volume Device: /dev/asm/vol1-280
State: ENABLED
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 is a normal redundancy disk group with 5 GB of free space.
To increase the size of the ACFS file system, you execute this command as the root user:
$ /sbin/acfsutil size +200M /u01/app/grid/acfsmount
Which two statements are true regarding the outcome of this command?

• A.It fails to resize the filesystem because it must be unmounted before resizing.
• B.It succeeds but leaves the filesystem unmounted.
• C.It fails to resize VOL1 because it must be executed as a user belonging to the SYSASM group.
• D.It resizes VOL1.
• E.It resizes the filesystem mounted on /u01/app/grid/acfsmount.

Which two statements are true about the Global Enqueue Service, Instance Locks, and global enqueues in Oracle 12c RAC?

• A.In a RAC database, there is no LMD0 process if only one instance is running.
• B.Global Enqueues may have converters and waiters in the same instance.
• C.Global Enqueues and Instance Locks replace mutexes completely in RAC database instances.
• D.Global Enqueues may have owners and waiters in the same instance.
• E.Global Enqueues and Instance Locks replace latches completely in RAC database instances.
• F.In a RAC One Node database, there is no LMD0 process if only one instance is running.

You plan to create a three-instance RAC database stored in ASM, with its data files in the DATA disk group.
Identify three supported storage solutions for the Fast Recovery Area (FRA).

• A.a cluster file system
• B.a local file system with the same path name on each cluster node
• C.a shared NFS file system
• D.a shared nothing file system accessed directly by the database instances
• E.the DATA disk group

Examine the output of the asmcmd and srvct1 commands:

You execute this command:
$ srvctl modify asm -count 2
All databases on the cluster are running from Oracle 12c homes.
Which statement is true about the outcome of this command?

• A.One ASM instance is shut down and the instance count is reduced by one.
• B.The command fails because one ASM instance must be shut down manually before executing the command.
• C.The command fails because the instance count cannot be reduced to less than the minimum value of 3.
• D.ASM instances continue running on all three nodes until all database instances connected to one of the ASM instances shut down.

Which two utilities support the "what-if" command evaluation?

• A.oifcfg
• B.srvctl
• C.asmcmd
• D.crsctl
• E.ocrconfig
