NEW QUESTION 1
You have Solaris 11 system with a host name of sysA and it uses LDAP as a naming service.
You have created a flash archive of sysA and you want to migrate this system to an Oracle Solaris11 server, Solaris10 branded zone.
The zone Status on the Oracle Solaris 11 server is:
- zone10 incomplete/zone/zone1solaris10exc1
Select the option that will force the non-global zone to prompt you for a host name and name service the first time it is booted.

• A. Use zonecfg to change the zonename before booting the system for the first time
• B. Use the - u option with the zoneadm - z zone10 attach command.
• C. Use the -u option with the zoneadn -z zone10 install command.
• D. Remove the sysidcfg file from the <zonepath>/root directory before booting the non- global zone.

Answer: C

Explanation: Oracle Solaris 10 branded zones – Oracle Solaris 10 Zones provide an Oracle Solaris 10
environment on Oracle Solaris 11. You can migrate an Oracle Solaris 10 system or zone to a solaris10 zone on an Oracle Solaris 11 system in the following ways:
* Create a zone archive and use the archive to create an s10zone on the Oracle Solaris 11 system.
This option applies in the current scenario.
Example of command to Install the Oracle Solaris 10 non-global zone. s11sysB# zoneadm -z s10zone install -u -a /pond/s10archive/s10.flar
* Detach the zone from the Oracle Solaris 10 system and attach the zone on the Oracle Solaris 11 zone. The zone is halted and detached from its current host. The zonepath is moved to the target host, where it is attached.
Note:
install [-x nodataset] [brand-specific options] A subcommand of the zoneadm.
Install the specified zone on the system. This subcommand automatically attempts to verify first. It refuses to install if the verify step fails.
-u uuid-match
Unique identifier for a zone, as assigned by libuuid(3LIB). If this option is present and the argument is a non-empty string, then the zone matching the UUID is selected instead of the one named by the -z option, if such a zone is present.

NEW QUESTION 2
In a default standalone installation of Oracle Solaris 11, what is the default minimum length in characters of a user password, and where is the minimum password length defined?

• A. Default minimum length is 8, and is defined in /etc/default/password.
• B. Default minimum length is 6, and is defined in /etc/default/password.
• C. Default minimum length is 8, and is defined in /etc/shadow.
• D. Default minimum length is 6, and is defined in /etc/shadow.
• E. Default minimum length is 8, and is defined in /usr/sadm/defadduser.
• F. Default minimum length is 6, and is defined in /usr/sadm/defadduser.

Answer: B

Explanation: By default, the passwd command assumes a minimum length of six characters. You can use the PASSLENGTH default in the /etc/defaults/passwd files to change that by setting the minimum number of characters that a user's password must contain to some other number.

NEW QUESTION 3
You need to update an OS image on a client. The pkg publishers command displays the wrong publisher with the wrong update:
PUBLISHERTYPESTATUSURI
Solaris origin onlinehttp://pkg.oracle.com/solaris/release
The update is available on the updated publisher: PUBLISHERTYPESTATUSURI
Solaris originonlinehttp://sysA.example.com
Select the option that describes the procedure used to update the OS image on the system from the updated publisher.

• A. Copy the repository from the ISO image onto the local clien
• B. Configure the repository on the client by using the svccfg - s command so that the Solaris publisher is connected to the new repositor
• C. Refresh the application/pkg/server servic
• D. Issue the pkgrepo refresh command to refresh the repository catalog
• E. Configure the publisher on the client using the svcfg - s command so that the Solaris publisher is connected to the repository at http://sysA.example.comRefresh the application/pkg/server servic
• F. Issue the pkgrepo refresh command to repository catalog
• G. Use the pkg set-publisher command to change the URL of the publisher Solaris to http://sysA.example.co
• H. Issue the pkg update command to update the OS image.
• I. Add the new publisher http://sysA.example.com SolarisUse the pkg set-publisher command to set the publisher search order and place http://sysA.example.com of http://pkg.oracle.com/solaris/releaseIssue the pkg publisher command to view the publisher
• J. Set the new publisher to stick
• K. Issue the pkg update command to update the OS image.

Answer: C

Explanation: You can use the pkg set-publisher command to change a publisher URI. Changing a Publisher Origin URI
To change the origin URI for a publisher, add the new URI and remove the old URI. Use the -g option to add a new origin URI. Use the -G option to remove the old origin URI.
# pkg set-publisher -g http://pkg.example.com/support
-G http://pkg.example.com/release example.com
Note: You can use either the install or update subcommand to update a package.
The install subcommand installs the package if the package is not already installed in the image. If you want to be sure to update only packages that are already installed, and not install any new packages, then use the update subcommand.

NEW QUESTION 4
Review the boot environment information displayed on your system:

Which two options accurately describe the newBE boot environment?

• A. It cannot be destroyed.
• B. It cannot be activated.
• C. It cannot be renamed.
• D. You can create a snapshot of it.
• E. It is activated but unbootable.
• F. It has been deleted and will be removed at the next reboot.

Answer: BC

Explanation: If the boot environment is unbootable, it is marked with an exclamation point (!) in the
Active column in the beadm list output.
The beadm command restricts actions on unbootable boot environments as follows: You cannot activate an unbootable boot environment. (B)
You cannot destroy a boot environment that is both unbootable and marked as active on reboot.
You cannot create a snapshot of an unbootable boot environment.
You cannot use an unbootable boot environment or boot environment snapshot with the -e option of beadm create.
You cannot rename an unbootable boot environment. (C)

NEW QUESTION 5
Choose three options that describe the features associated with a Live Media installation.

• A. does not allow the root user to log in to the system directly from the console (or any terminal)
• B. provides a "hands free" installation
• C. installs the desktop based packages
• D. can be used to install only x86 platforms
• E. installs the server-based set of packages only
• F. allows both automatic and manual configuration of the network
• G. installs both the server-based and desktop-based package

Answer: BCD

Explanation: The graphical installer is officially known as the "Live Media." This means that Oracle Solaris can be booted into RAM, causing zero impact on your existing operating system. After it is loaded, you are free to experiment with Oracle Solaris to determine whether it is something you would like to install to your system.
You can download Oracle Solaris 11 Live Media for x86, which is an approximately 800 MB image file, and use a DVD burner to create the disk, or you can use the ISO image directly in a virtual machine or through the Oracle Integrated Lights Out Manager (ILOM) Remote Console.
The Live Media is not intended for long-term use. For example, any changes that you make
to the system are lost when the system is shut down. Therefore, the next logical step is to install Oracle Solaris on the system, which the Live Media makes easy by placing an Install Oracle Solaris icon right on the desktop. But before we head down that road, let's step back a bit and consider the installation options.
Note: The Live Media provides administrators with an opportunity to explore the Oracle Solaris 11 environment without installing it on a system. The system boots off the media directly allowing administrators to start the installer should they choose to install it to a system.

NEW QUESTION 6
The core dump configuration in your non global zone is

A user is running a process in a non-global zone (testzone) and the process crashes. The process information is:
user126632618017:46:42pts/20:00/usr/bin/bash
When the user's process crashes in testzone, a non-global zone, where will the core dump be saved?

• A. The file will be stored in the non-global zone's directory:/var/core/pprocess/core.hash.2663.
• B. The file will be saved in the global zone's directory: /var/core/core.bash.2663.
• C. A core file cannot be generated in a non-global zone because it shares the kernel with the global zone.
• D. The file will be stored in the global zone's directory: /var/core/pprocess/core.bash.2663.
• E. The file will be saved in non-global zone’s directory: /var/core/core.bash.2663

Answer: E

Explanation: The line
init core file pattern: /var/core/core.%f.%p
will be used for the non-global process to determine the destination of the dump file.
Note: When a process is dumping core, up to three core files can be produced: one in the per-process location, one in the system-wide global location, and, if the process was running in a local (non-global) zone, one in the global location for the zone in which that process was running.

NEW QUESTION 7
Which operation will fail if the DNS configuration is incorrect?

• A. domainname
• B. ping localhost.
• C. ping 192.168.1.1
• D. ping 23.45.82.174
• E. ping www.oracle.com.
• F. cat /etc/resolv.conf

Answer: E

Explanation: www.oracle.com would have to be resolved to an IP name by the domain name service.

NEW QUESTION 8
You are attempting to troubleshoot an event that should have made an entry into the messages log. This event happened about two weeks ago. Which file should you look at
first?

• A. /var/adm/messages
• B. /var/adm/messages.0
• C. /var /adm/messagas.1
• D. /var/adm/messages.2
• E. /var/adm/messages.3

Answer: A

Explanation: The /var/adm/messages is the file to which all the messages printed on the console are logged to by the Operating System. This helps to track back check the console messages to troubleshoot any issues on the system.
Syslog daemon also writes to this /var/adm/messages file.
The /var/adm/messages file monitored and managed by newsyslog and its configuration file is /usr/lib/newsyslog.
This script runs as the roots cron job everyday, checks the /var/adm/messages file and copies/moves it to /var/adm/messages.0, 1, 2, 3, 4, 5, 6, 7. In other words, it does the Log Rotation for the /var/adm/messages.
In an event the /var file system is running out of space, these files needs to checked and can be removed (not the actual /var/adm/messages itself) to free up space on the file system.
However, care has to be taken, if you decide to empty the /var/adm/messages itself for any reason. This process is called Truncation.
SOLARIS SYSTEM ADMIN TIPS, /var/adm/messages

NEW QUESTION 9
When setting up Automated Installer (AI) clients, an interactive tool can be used to generate a custom system configuration profile. The profile will specify the time zone, data and time, user and root accounts, and name services used for an AI client installation. This interactive tool will prompt you to enter the client information and an SC profile (XML) will be created.
Which interactive tool can be used to generate this question configuration?

• A. sys-unconfig
• B. installadm set-criteria
• C. sysconfig create-profile
• D. installadm create-profile

Answer: B

Explanation: Use the installadm set-criteria command to update the client criteria associated with an AI manifest that you already added to a service using installadm add-manifest.
Use the installadm add-manifest command to add a custom AI manifest to an install service.
The value of manifest is a full path and file name with .xml extension. The manifest file contains an AI manifest (installation instructions). The manifest file can also reference or embed an SC manifest (system configuration instructions).

NEW QUESTION 10
What is the result of executing the following command? svcs -d svc:/network/ssh:default

• A. disables the svc:/network/ssh:default service
• B. displays the services that svc: /network/ssh:default is dependent on
• C. displays the services that are dependent on the svc: /network/ssh:default service
• D. deletes the svc: /network/ssh:default service

Answer: B

Explanation: The svcs command displays information about service instances as recorded in the service configuration repository.
-d Lists the services or service instances upon which the given service instances depend.

NEW QUESTION 11
On which is the open boot prom available?

• A. x86 only
• B. x86 64-Bit only
• C. SPARC only
• D. both x86 and x86 64-Bit
• E. x86, x86 64-Bit and SPARC

Answer: C

Explanation: No OpenBoot Environment on the Intel Platform. The Intel environment has no OpenBoot PROM or NVRAM. On Intel systems, before the kernel is started, the system is controlled by the basic input/output system (BIOS), the firmware interface on a PC. Therefore, many features provided by OpenBoot are not available on Intel systems.
Note: The Open Boot PROM (OBP) bootloader only exists within SPARC. Before Solaris 10 01/06, the bootloader for Solaris x86 was a Sun customized bootstrap software. After Solaris 10 01/06, it uses GRUB, a well known bootloader that's commonly used in the
Linux world.
With GRUB, it's much easier to make the system dual-boot Linux and Solaris. GRUB extends the capabilities of the bootloader that was not available previously such as the ability to boot from a USB DVD drive. Those who have used Linux will be quite familiar with GRUB and its options.

NEW QUESTION 12
Solaris 11 includes a redesigned software packaging model: the Image Packaging system.
Which three describe advantages of the Image Packaging System over the previous Solaris 10 SVR4 packaging model?

• A. Eliminates patching of the software package
• B. Makes the patching process more efficient with less downtime
• C. Eliminates OS version upgrade
• D. Allows for the installation of the OS without a local DVD or installation server
• E. Allows the use of a repository mirror to speed up package operation
• F. Allows users to publish their own software package in a software repository

Answer: AEF

NEW QUESTION 13
You have been asked to terminate a process that appears to be hung and will not terminate. The process table is shown below:
root 15163 15156 0 12:51:15 pts/3 0:00 hungscript What command will terminate the process?

• A. kill -9 15163
• B. kill -1 15163
• C. kill -15 15163
• D. kill -2 15163

Answer: A

Explanation: Here we should use SIGTERM to terminate the process. Note:
When no signal is included in the kill command-line syntax, the default signal that is used is
–15 (SIGKILL). Using the –9 signal (SIGTERM) with the kill command ensures that the process terminates promptly. However, the –9 signal should not be used to kill certain processes, such as a database process, or an LDAP server process. The result is that data might be lost.
Tip - When using the kill command to stop a process, first try using the command by itself, without including a signal option. Wait a few minutes to see if the process terminates before
using the kill command with the -9 signal.

NEW QUESTION 14
Which two accurately identify features of a Solaris 10 branded zone?

• A. executes in a Solaris 10 global zone
• B. is created by importing a Solaris 10 flash archive
• C. enables Linux binary applications to run unmodified
• D. provides a complete runtime environment for Solaris 9 applications
• E. allows a Solaris 10 global zone to be migrated into a Solaris 10 non-global zone on a Solaris 11 system

Answer: BE

Explanation: B: It can be created by importing a Solaris 10 flash archive.
You can use the Oracle Solaris Flash archiving tools to create an image of an installed
system that can be migrated into a zone.
The system can be fully configured with all of the software that will be run in the zone before the image is created. This image is then used by the installer when the zone is installed.
Note: You can use alternate methods for creating the archive. The installer can accept the following archive formats:
* cpio archives
* gzip compressed cpio archives
* bzip2 compressed cpio archives
* pax archives created with the -x xustar (XUSTAR) format Ä ufsdump level zero (full) backups
Note:
Branded zones that run an environment different that the OS release on the system
* The lx branded zone introduced in the Solaris 10 8/07 release provides a Linux environment for your applications and runs on x86 and x64 machines on the Oracle Solaris 10 OS.
* The solaris8 and solaris9 branded zones enable you to migrate an Oracle Solaris 8 or Oracle Solaris 9 system to an Oracle Solaris 8 or Oracle Solaris 9 Container on a host running the Oracle Solaris 10 8/07 Operating System or later Oracle Solaris 10 release.
* The Oracle Solaris 10 Container brand is available in OpenSolaris build 127. These branded zones host Oracle Solaris 10 user environments.
Note: One of the powerful features of Solaris 11 is the ability to run a Solaris 10 environment in a zone. Solaris 10 allows you to run Solaris 8 and 9 environments in zones, but only on SPARC.

NEW QUESTION 15
Which five statements describe options available for installing the Oracle Solaris 11operating system using the installation media?

• A. You can perform a text or LiveCD installation locally or over the network.
• B. The text Installer does not install the GNOME deskto
• C. The GNOME desktop package must he added after you have installed the operating system.
• D. The LiveCD Installation cannot be used to install multiple instances of Oracle Solaris.
• E. The LiveCD installer cannot be used if you need to preserve a specific Solaris Volume Table of Contents (VTOC) slice in your current operating system.
• F. The LiveCD Installer is for x86 platforms only.
• G. The GUI installer cannot be used to upgrade your operating system from Solaris 10.
• H. If you are installing Oracle Solaris 11 on an x86-based system that will have more than one operating system installed in it, you cannot partition your disk during the installation process.
• I. The LiveCD installer can be used for SPARC or x86 platforms.

Answer: ABDFH

Explanation: A: If the network is setup to perform automated installations, you can perform a text installation over the network by setting up an install service on the network and selecting a text installation when the client system boots.
B: After a fresh install of Solaris 11 express, only the console mode is activated. To add Gnome, simply do :
$ sudo pkg install slim_install
This will install additional packages that are not installed by default. D: The text installer advantages over the GUI installer include:
* In addition to modifying partitions, the text installer enables you to create and modify VTOC slices within the Solaris partition.
F: How do I upgrade my Solaris 10 or lower systems to Solaris 11?
Unfortunately, you CAN'T. There is no direct upgrade installer or other tool that will allow you to upgrade from earlier releases of Solaris to Solaris 11. This is primarily due to the vast changes in the packaging mechanism in Solaris 10.

NEW QUESTION 16
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

Explanation: Use the pkg search command to search for packages whose data matches the specified pattern.
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
You upgraded your server to Oracle Solaris 11 and you imported zpool (pool1) that was created in Solaris 10. You need to create an encrypted ZFS file system in pool1, but first you need to make sure that your server supports ZFS encryption.
Which four statements are true for support of ZFS encryption?

• A. The encrypted file system must have been created in Oracle Solaris11. To encrypt a ZFS file system from a previous version of Solaris, upgrade the zpool and create a new encrypted ZFS file system into the encrypted ZFS file system.
• B. If you plan to create an encrypted file system in an existing zpool, the zpool must beupgraded to ZFS version 30.
• C. ZFS encryption is integrated with the ZFS command set and no additional packages need to be installed.
• D. ZFS encryption requires that the ZFS Dataset Encryption package be installed.
• E. If you plan to create an encrypted file system in an existing zpool, the pool must be upgraded to ZFS version 21, minimum.
• F. Encryption is supported at the pool or dataset (file system) level.
• G. Encryption is supported at the pool level only for every file system in the pool will be encrypted.
• H. You cannot create an encrypted file system in a zpool that was created prior to oracle Solaris11. Create a new zpool in Solaris11, create an encrypted ZFS file system in the new zpool, and move or copy the data from the existing file system into the new encrypted file system.

Answer: ABCF

Explanation: A (not H): You can use your existing storage pools as long as they are upgraded. You have the flexibility of encrypting specific file systems.
B (not E): Can I enable encryption on an existing pool?
Yes, the pool must be upgraded to pool version 30 to allow encrypted ZFS file systems and volumes.
C (not D): ZFS encryption is integrated with the ZFS command set. Like other ZFS operations, encryption operations such as key changes and rekey are performed online. F (not G): Encryption is the process in which data is encoded for privacy and a key is needed by the data owner to access the encoded data. You can set an encryption policy when a ZFS dataset is created, but the policy cannot be changed.
