The rctladm command reports the following:
# rctladm |grep task.max.lwps task.max-lwps syslog=notice [ count 1
Which of the following correctly describes the system configuration?
A. The global resource control monitoring for the task.max-lwps resource control has been enabled, syslog messaging for that resource control has been set to notice.
B. A message will be logged with syslogd when the number of notice messages generated by the resource control threshold meets or exceeds the value specified with [count]
C. The global resource control monitoring for the task.max-lwps resource control has been enabled and syslog messaging for that resource control has been set to notice. However, because the [count] value has not been specified, there is no threshold set for the resource to monitor. The configuration to monitor the task.max-lwps resource control is incomplete.
D. A message will be logged with sysloqd when the number of violations generated by the resource control threshold meets or exceeds the value specified with [count].

質問 6：
You need to migrate a UFS file system named /production_ufs to a ZFS file system named /production_ufs. The /production_ufs file system cannot be taken down or be out of production during the migration, and the current /production_ufs file system must remain active until the /ptoduction_zfs file system is copied and ready.
Which method allows you to meet both requirements?
1.Copy live data from /production_ufs to /production_zfs while /production_ufs is in use.
2.When the copy is complete, /production_zfs will contain an up-to date copy of
/production_ufs
A. Create a new Boot Environment.
Create the ZFS file system.
Use lucreate -m to copy data from the Current UFS file system to the new ZFS file system.
B. Create the new ZFS file system by using zfs create import to import data from the
existing UFS file system into the new ZFS file system
C. Mirror the existing UFS file system by using SVM.
After both submissions are in sync, migrate one of the submissions to a ZFS file System by
using Live Upgrade.
D. Create a snapshot of the UFS file system.
Create the new ZFS file system.
Use cpio to copy data from the snapshot to the new ZFS file system.
E. Create the new zfs file system by using the zfs create -o shadow.
