prompts you to create a root password and a user account.
Which four describe your options for completing this panel of the Installation?

• A. Creating a user account is optional.
• B. The root password must be set and cannot be blank.
• C. The root password can be left blank.
• D. If you provide a username, that user is assigned the root role.

Answer: ABDG

Explanation: A: You are not required to create a user account. B: You must create a root password.
D: If you create a user account in this panel, you need to provide both the user's password and a root password.
In this case, root will be a role assigned to the user.

NEW QUESTION 7
Review the storage pool information:

Choose the correct procedure to repair this storage pool.

• A. Shut the system down, replace disk c3t3d0, and boot the syste
• B. When the system is booted, execute the zpool clear pool1 command.
• C. Shut the system down, replace disk c3t3d0, and boot the syste
• D. When the system is booted execute the zpool online pool1 command.
• E. Shut the system down, replace disk c3t3d0, and boot the syste
• F. When the system is booted, execute the zpool replace pool1 c3t3d0 command.
• G. Shut the system down, replace disk c3t3d0, and boot the syste
• H. When the system is booted, execute the zpool replace pool1 c3t3d0 c3t3d0 command.

Answer: C

Explanation: You might need to replace a disk in the root pool for the following reasons: The root pool is too small and you want to replace it with a larger disk
The root pool disk is failing. In a non-redundant pool, if the disk is failing so that the system won't boot, you'll need to boot from an alternate media, such as a CD or the network, before you replace the root pool disk.
In a mirrored root pool configuration, you might be able to attempt a disk replacement without having to boot from alternate media. You can replace a failed disk by using the zpool replace command.
Some hardware requires that you offline and unconfigure a disk before attempting the zpool replace operation to replace a failed disk.
For example:
# zpool offline rpool c1t0d0s0
# cfgadm -c unconfigure c1::dsk/c1t0d0
<Physically remove failed disk c1t0d0>
<Physically insert replacement disk c1t0d0>
# cfgadm -c configure c1::dsk/c1t0d0
# zpool replace rpool c1t0d0s0
# zpool online rpool c1t0d0s0
# zpool status rpool
<Let disk resilver before installing the boot blocks>
SPARC# installboot -F zfs /usr/platform/`uname -i`/lib/fs/zfs/bootblk /dev/rdsk/c1t0d0s0 x86# installgrub /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c1t9d0s0

NEW QUESTION 8
You are attempting to edit your crontab file in the bash shell. Instead of getting your usual vi interface, you are presented with an unfamiliar interface. In order to have your editor of choice-vi- what command must you type after exiting the unfamiliar editor?

• A. EDITOR=vi
• B. crontab=vi
• C. crontab – e vi
• D. env

Answer: A

Explanation: Set the EDITOR variable to vi.
Commands like `crontab -e` will use ed per default. If you'd like to use some better editor (like vi) you can use the environment variable EDITOR:
# EDITOR=vi; crontab –e will open the users crontab in vi. Of course you can set this variable permanently.
Incorrect answers
C: -e Edits a copy of the current user's crontab file, or creates an empty file to edit if crontab does not exist. When editing is complete, the file is installed as the user's crontab file. If a username is given, the specified user's crontab file is edited, rather than the current user's crontab file; this can only be done by a user with the solaris.jobs.admin authorization. The environment variable EDITOR determines which editor is invoked with the -e option. The default editor is ed(1). All crontab jobs should be submitted using crontab. Do not add jobs by just editing the crontab file, because cron is not aware of changes made this way.

NEW QUESTION 9
You have been tasked with creating a dedicated virtual network between two local zones within a single system, in order to isolate the network traffic from other zones on that system.
To accomplish this, you will create .

• A. an ether stub
• B. virtual router
• C. a virtual bridge
• D. a virtual network interface
• E. nothing, because a virtual switch is automatically created when the virtual network interfaces are created

Answer: D

Explanation: First create a virtual switch, then create a virtual network interface.

NEW QUESTION 10
Which command would you use from the bash shell to determine the total amount of physical memory installed in your Solaris system (x86 and SPARC)?

• A. uname –a
• B. prtconf | grep –i memory
• C. sysdef | grep –i memory
• D. vmstat
• E. prtdiag | grep –i memory

Answer: B

Explanation: The prtconf command prints the system configuration information. The output includes the total amount of memory, and the configuration of system peripherals formatted as a device tree.
If a device path is specified on the command line for those command options that can take a device path, prtconf will only display information for that device node.

NEW QUESTION 11

NEW QUESTION 13
You enter dladm show-phys, which provides the following output:

You then enter: ipadm create-ip net3
What is the output?

• A. ipadm: cannot; create interface net3: Operation failed.
• B. ipadm: cannot create interface net3: Interface already exists.
• C. ipadm: cannot create interface net3: IP address object not specified.
• D. No_response, The command was successful.

Answer: B

Explanation: According to the exhibit the interface already exists.
The command ipadm create-ip net3 is supposed to create a new interface net3.

NEW QUESTION 14
You start to execute a program by using the following command:
~/bigscript &
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?

• A. 15163
• B. 15156
• C. 15166
• D. 15165

Answer: A

Explanation: 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.

You need to install the solaris-desktop group package. Which command would you use to list the set of packages included in that software group?

• A. pkg search
• B. pkg info
• C. pkginfo
• D. pkg contents

Answer: A

Like the pkg contents command, the pkg search command examines the contents of packages. While the pkg contents command returns the contents, the pkg search
command returns the names of packages that match the query.

NEW QUESTION 17
View the Exhibit to inspect the boot environment Information displayed within a non global zone on your system.

Which two options describe the solaris-1 boot environment?

• A. The solaris-1 boot environment is not bootable.
• B. The solaris-1 boot environment is incomplete.
• C. The solaris-1 boot environment was created automatically when the non global zone was created.
• D. The solaris-1 boot environment was created in the non-global zone using the beadm create command.
• E. The solaris-1 boot environment is associated with a non active global zone boot environment.

Answer: AE

Explanation: A: The – of the Active Column indicates that this boot environment is inactive, and hence not bootable.
Note: The values for the Active column are as follows: R – Active on reboot.
N – Active now.
NR – Active now and active on reboot. “-” – Inactive.
“!” – Unbootable boot environments in a non-global zone are represented by an exclamation point.
