This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the Oracle Solaris 11 Installation and Configuration Essentials exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by Oracle in their Oracle 1Z0-580 exam. These outdated questions lead to customers failing their Oracle Solaris 11 Installation and Configuration Essentials exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the Oracle 1Z0-580 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
What two features identify Oracle Solaris 11 as being "built for clouds"?
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
What is the expected behavior when running the following command on an x86 system?
# boot net:dhcp
The x86 systems cannot be told to network boot like sparc systems (ie. boot net - install).
Note:
* How to Boot a SPARC Based System From the Network
1. Become the root role.
2. If necessary, bring the system to the ok PROM prompt.
# init 0
3. Boot the system from the network without using the ''install ''flag.
ok boot net:dhcp
Note - If you have changed the PROM setting to boot with DHCP by default, you only have to specify boot net, as shown here:
ok boot net
What is the relevance of the "-c" argument in the output below?
pkgrecv
- Image Packaging System content retrieval utility
Options include:
-c cache_dir
The path to a directory that will be used to cache downloaded content. If this directory is not supplied, the client automatically selects a cache directory. In the case where a download is interrupted, and a cache directory was automatically chosen, use this option to resume the download. See the ''Environment Variables'' section below for details about how to set the location used for temporary data storage.
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?
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 read---only root restricts access to the runtime environment from inside the zone.
Which is the preferred command to manage Layer 3 network properties in Oracle Solaris 11?
Interfaces that are on the IP layer (Layer 3) are configured by using the ipadm command.
