View the Exhibit and review the zpool and ZFS configuration information from your system.
Identify the correct procedure for breaking the /prod_data mirror,removing c4t0d0 and c4t2d0,and making the data on c4t0d0and c4t2d0 accessible under the dev_data mount point.
A. zpool split pool1 pool2 c4t0d0 c4t2d0zpool import pool2zfs set mountpoint = /dev_data pool2/prod_data
B. zpool detach pool1 pool2zpool attach pool2zfs set mountpoint=/dev_data pool2/prod_data
C. zpool split pool1/prod_data -n pool2/dev_datazfs set mountpoint = /dev_data pool2/prod_data
D. zpool split pool1 pool2 c4t0d0 c4t2d0zpool import pool2
In this Solaris release,you can use the.zpool split.command to split a mirrored storage pool,which detaches a disk or disks in the original mirrored pool to create another identical pool. After the split operation,import the new pool.

What determines which bits in an IP address represent the subnet,and which represent the host?
A subnetwork,or subnet,is a logically visible subdivision of an IP network. The practice of
dividing a network into two or more networks is called subnetting.
The routing prefix of an address is written in a form identical to that of the address itself.
This is called the network mask,or netmask,of the address. For example,a specification of
the most-significant 18 bits of an IPv4 address,11111111.11111111.11000000.00000000,is
written as 255.255.192.0.

What are the two problems with your plan?
A. Group names may not contain a numeric character
B. Group names may be no longer than 7 characters.
C. Group numbers should not be larger than 60000.
D. Group names should be all lowercase.
C: The Group ID (GID) field contains the group's numerical ID. GIDs can be assigned whole numbers between 100 and 60000.
D: Group names contain only lowercase characters and numbers.

You are having an issue with the shutdown command. You wish to determine if the file is a script or an executable program. Which command would you use to determine this?
A. od shutdown
B. file shutdown
C. test shutdown
D. cksum shutdown
E. attrib shutdown
The file command determines the file type file tests each argument in an attempt to classify it. There are three sets of tests,performed in this order: filesystem tests,magic tests,and language tests. The first test that succeeds causes the file type to be printed.

To assist in examining and debugging running processes,Solaris 11 has a utility that returns pro arguments and the names and values of environment variables.

You start to execute a program by using the following command:
You then determine that the process is not behaving as expected,and decide that you need
to terminate the process.
Based on the information shown below,what is the process number you should terminate?
From the output exhibit we can deduce that the shell has id 15156.
It has spawned three subprocesses:
grep: id 15166
ps –aef 15165
The remaining 15163 must be the subshell (see note below).
This is the id of the process which should be terminated.
