Oracle 1Z0-580 Exam Questions

A snapshot is a read-only point-in-time copy of a file system. The copy-on-write design

of ZFS makes them essentially ''free'' - They are space efficient and instantaneous, providing an invaluable part of backup strategies and synchronizing data between systems.

Incorrect:

Incorrect:

Not A: A ZFS vdev (aka 'virtual device') is either:

a single disk, or

two or more disks that are mirrored, or

a group of disks that are organized using RAID-Z.

There are also special kinds of vdevs like hot-spares, ZIL or cache devices, etc.

Not D:

Clones are writeable snapshots, ideal for storing many private

copies of shared data for operations such as data migration, test

and development, or backup.

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.

Tasks such as installing and updating IPS packages, setting publishers, and modifying images require more privilege.

Incorrect answers:

Getting Information About Software Packages

No special privileges are needed to run any of the following commands.

Commands that give you the following kinds of information about packages:

(not A) Whether the package is installed or can be updated

The description, size, and version of the package

(not B) Which packages are part of a group package

(not C) Which packages are in a particular category

(not D) Which package delivers a specified file

No special privileges are needed to run any of these commands.

You can display information about snapshots, boot environments, and datasets that were created by the beadm command by using the beadm list subcommand. The beadm list command output also displays boot environments that are created by the pkg command.

Viewing Boot Environment Specifications

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.

The following example displays full information for the BE5 boot environment.

B:

* With Oracle Solaris 11, the configuration of the system is specified as a set of configuration parameters provided in a file called the System Configuration Profile, which is in the form of an SMF profile.

* Oracle Solaris 11 uses SMF for configuration. SMF uses a database to centralize the configuration information, it uses the SMF framework to carry out configuration tasks, and it uses SMF properties as an API. SMF is also well integrated with Oracle Solaris Zones technology.

* Oracle Solaris 11 uses the Service Management Facility (SMF) to centralize configuration information. The new sysconfig command replaces the older sys-unconfig command and provides a method based upon SMF for unconfiguring an Oracle Solaris 11 instance and reconfiguring it.

D: To use AI to install client systems over the network, you must set up DHCP and set up an AI service on an AI server.

An AI service is associated with a SPARC or x86 AI install image and one or more sets of installation instructions.

Note:

Using the Oracle Solaris Automated Installer (AI) you can create and manage services to install the Oracle Solaris 11 operating system over the network in a hands-off manner.

Three significant steps are performed by various services during the installation process:

Assigning a network identity for the system being installed

Contacting the automated installation service to download over the network a small boot image and a description of how to provision a system

Provisioning the system over the network, including software and system configuration

Each of the steps can be performed by various services residing on the same physical or virtual system, or the services can be on separate systems. In this article, the following services reside on the same system:

DHCP service

Automated Installer service

Image Packaging System (IPS) repository service
