A customer has multiple applications and you believe consolidation using Oracle Solaris Zones will
help them. The customer is concerned that consolidating them all on one physic server may cause
adverse interactions between them, causing problems with functionality, security, and performance.
What are the two benefits of Zones that would explain why Zones would be a good choice?
B, E
Explanation:
B (not C): A zone is a virtualized operating system environment that is created within a single
instance of the Oracle Solaris operating system. Oracle Solaris Zones are a partitioning technology
that provides an isolated, secure environment for applications.
Note:
* When you create a zone, you produce an application execution environment in which processes are
isolated from the rest of the system. This isolation prevents a process that is running in one zone
from monitoring or affecting processes that are running in other zones. Even a process running with
root credentials cannot view or affect activity in other zones. A zone also provides an abstract layer
that separates applications from the physical attributes of the machine on which the zone is
deployed. Examples of these attributes include physical device paths and network interface names.
The default non-global zone brand in the Oracle Solaris 11.1 release is the solariszone.
By default, all systems have a global zone. The global zone has a global view of the Oracle Solaris
environment that is similar to the superuser (root) model. All other zones are referred to as non-
global zones. A non-global zone is analogous to an unprivileged user in the superuser model.
Processes in non-global zones can control only the processes and files within that zone. Typically,
system administration work is mainly performed in the global zone. In rare cases where a system
administrator needs to be isolated, privileged applications can be used in a non-global zone. In
general, though, resource management activities take place in the global zone.

A zone won't boot. Identify the five causes.
A, B, C, D, E
Explanation:
A: dedicated-cpu Resource
The dedicated-cpu resource specifies that a subset of the system's processors should be dedicated to
a non-global zone while it is running. When the zone boots, the system will dynamically create a
temporary pool for use while the zone is running.
C: s the global administrator in the global zone, you can import raw and block devices into a non-
global zone. After the devices are imported, the zone administrator has access to the disk. The zone
administrator can then create a new file system on the disk and perform one of the following actions:
Mount the file system manually
Place the file system in /etc/vfstab so that it will be mounted on zone boot
D, E: Booting a zone places the zone in the running state. A zone can be booted from the ready state
or from the installed state. A zone in the installed state that is booted transparently transitions
through the ready state to the running state. Zone login is allowed for zones in the running state.
Incorrect:
Not F: Sys_time not related to booting a zone.
Which two statements are true of the GRUB menu?
A, C
Explanation:
A:
* If your system has more than one OS installed on the system or more than one root boot
environment in a ZFS root pool, you can boot from these boot environments for both SPARC and x86
platforms.
* GRUB, the open source boot loader, is the default boot loader in the Solaris OS.
C: With GRUB based booting, the kernel is loaded by specifying its file name, and the drive, and the
partition where the kernel resides. GRUB based booting replaces the Solaris Device Configuration
Assistant and simplifies the booting process with a GRUB menu.
Incorrect:
Not E:
* In this implementation of GRUB, the multiboot module is no longer used.
What two features identify Oracle Solaris 11 as being "built for clouds"?
B, D
Explanation:
B: Built-in Virtualization
Whatever the needs of your cloud infrastructure, Oracle has a comprehensive suite of built-in
virtualization technologies to compliment your business requirements.
Choose from Oracle Solaris Zones, OVM Server for SPARC, OVM Server for x86 and OVM VirtualBox.
With Oracle Solaris Zones, administrators can rapidly provision secure and isolated virtual
environments in which to deploy cloud applications and services.
D:
Oracle Solaris is the best platform for the cloud because it combines key computing elements -
operating system, virtualization, networking, storage management, and user environment - into a
stable, secure, mission-critical foundation that customers can depend on
Your installation has completed successfully and the system did not reboot automatically. Which
option would cause this?
C
Explanation:
auto_reboot Optional. Omitting the auto_reboot attribute is equivalent to setting the value of the
attribute to false. By default, AI does not automatically reboot the client after installation. To request
automatic reboot of the client after successful installation, specify auto_reboot="true".
Note:
* Example 1 Set the auto_reboot Attribute
$ aimanifest set /auto_install/ai_instance@auto_reboot false

Which is the preferred command to manage Layer 3 network properties in Oracle Solaris 11?
B
Explanation:
Interfaces that are on the IP layer (Layer 3) are configured by using the ipadm command.
When conducting an automated installation, the name of the resulting root pool is "rpool1." Which is
the direct cause of this?
A
What has become the default graphical user interface for Oracle Solaris 11 desktop operation?
B
Explanation:
The Solaris 11 release in November 2011 only contains GNOME as a full desktop.
Incorrect:
Not A: The Common Desktop Environment (CDE) is a desktop environment for Unix and OpenVMS,
based on the Motif widget toolkit. For a long period, it was the "classic" Unix desktop associated with
commercial Unix workstations. After a long history as proprietary software, it was released as free
software on 6 August 2012, under the GNU Lesser General Public License.
What answer includes three correct methods available to transition Oracle Solaris 10 environments
to Oracle Solaris 11?
D
Explanation:
There are no upgrade methods or tools available to transition from Oracle Solaris 10 to Oracle Solaris
11. You cannot use an installer to upgrade from Oracle Solaris 10 to Oracle Solaris 11.
Oracle Solaris 11 Transition Tools and Features
/ JumpStart Migration Utility (js2ai)
Used to convert Oracle Solaris 10 JumpStart rules and profiles to a format that is compatible with AI
manifest entries.
/ ZFS shadow migration feature
Used to migrate data from an existing file system to a new file system.
/ Oracle Solaris 11 support for Oracle Solaris 10 zones
Used to migrate your Oracle Solaris 10 application environments to an Oracle Solaris 11 system.
/ NFS file sharing and pool migration
Used to access shared files from an Oracle Solaris 10 system on an Oracle Solaris 11 system.
Used to import a ZFS storage pool from an Oracle Solaris 10 system into an Oracle Solaris 11 system.

Oracle Solaris 11
After installing and customizing an Oracle Solaris 11 non-global (solaris brand) zone, you execute
commands:
# zonecfg z myzone set file-mac-profile=fixed-configuration'
# zoneadm z myzone reboot
What is the impact of making this specific change?
E
Explanation:
Through the zonecfg utility, the file-mac-profile can be set to one of the following values (see note
below). All of the profiles except none will cause the /var/pkg directory and its contents to be read-
only from inside the zone.
* none
Standard, read-write, non-global zone, with no additional protection beyond the existing zones
boundaries. Setting the value to none is equivalent to not setting file-mac-profile property.
* strict
* fixed-configuration
Permits updates to /var/* directories, with the exception of directories that contain system
configuration components.
IPS packages, including new packages, cannot be installed.
Persistently enabled SMF services are fixed.
SMF manifests cannot be added from the default locations.
Logging and auditing configuration files can be local. syslog and audit configuration are fixed.
* flexible-configuration
Note:
zonecfg file-mac-profile Property
By default, the zonecfg file-mac-profile property is not set in a non-global zone. A zone is configured
to have a writable root dataset.
In a solaris read-only zone, the file-mac-profile property is used to configure a read-only zone root. A
readonly root restricts access to the runtime environment from inside the zone.
