Pre-flight checker
Live Media
Automated Install

Correct Answer: E
Explanation/Reference:
Storage
ZFS is the root file system on Oracle Solaris 11 offering a superior experience in terms of
manageability, scalability and data integrity. ZFS presents a pooled storage model that completely
eliminates the concept of volumes and the associated problems of partitions, provisioning, wasted
bandwidth and stranded storage. Thousands of file systems can draw from a common storage pool,
each one consuming only as much space as it actually needs. All operations are copy-on-write
transactions ensuring that the on-disk state is always valid.
Incorrect:
Not A: Network Auto-Magic (NWAM) is a project to simplify and automate network configuration on
Solaris. Network Auto-Magic generally refers to Network Profiles, which allow users to specify various
network configurations to be created depending on the current network conditions. The Service
Discovery project, which incorporates Multicast DNS into Solaris, also fell under the Network AutoMagic umbrella.
Not B: Pre-Flight Checker tool which can be used to check whether apps will work without modification
on Solaris 11
Not C: Network Auto-Magic is a project to simplify and automate network configuration on Solaris.

QUESTION 4
In planning a system's initial configuration, you realize that you may not have disk space to complete
an installation that contains all of Oracle Solaris 11 software. Which installation method would be your
safest bet to begin the interactive installation process?
A.
B.
C.
D.
E.
Automated installer
Text based installer
LiveMedia, or LiveDVD image
Distribution constructor
USB-based installer
Correct Answer: C
Explanation/Reference:
The Live Media provides administrators with an opportunity to explore the Oracle Solaris 11.1
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.
Note:
* You have several alternatives for where to install Oracle Solaris 11:
https://www.genuinedumps.com/1Z0-580-exam-questions.html
Inside a virtual machine on top of your existing operating system
On the bare metal as a standalone operating system
On the bare metal alongside your existing operating system(s) (multiboot scenario)
QUESTION 5
You have just completed a default Oracle Solaris 11 installation of a new server system. While testing
network connectivity from your desktop to the server, you find that you are not able to communicate
with the 'sendmail' service from your desktop. Why is this?
A.
B.
C.
D.
E.
By default, the 'sendmail' software is not installed.
By default, 'sendmail' is not enabled on the system.
By default, 'sendmail'' access is blocked by TCP Wrappers.
By default, 'sendmail' responds to local requests only.
By default, 'sendmail' is running on its encrypted port.
Correct Answer: D
Explanation/Reference:
Note:
* sendmail
* Enabling Access to Remote Clients
On an unmodified system, access to sendmail by remote clients is enabled and disabled through the
service management facility (see smf(5)). In particular, remote access is determined by the value of
the local_only SMF property:
svc:/network/smtp:sendmail/config/local_only = true
A setting of true, as above, disallows remote access; false allows remote access. The default value is
true.
The following example shows the sequence of SMF commands used to enable sendmail to allow
access to remote systems:
# svccfg -s svc:/network/smtp:sendmail setprop config/local_only = false
# svcadm refresh svc:/network/smtp:sendmail
# svcadm restart svc:/network/smtp:sendmail
QUESTION 6
Your system has two disk devices, c2t0d0 and c2t1d0, and two flash devices, c2t5d0 and c2t8d0.
Which command would you to create a storage pool named ''tank,'' which mirrors the disks and adds
the two flash devices as ''cache''?
A.
B.
C.
D.
E.
zpool create tank mirror c2t0d0 c2t1d0 mirror c2t5d0 c2t8d0
zpool create tank mirror c2t0d0 c2t1d0 log mirror c2t5d0 c2t8d0
zpool c2t0d0 c2t1d0 cache c2t5d0 c2t8d0 mirror
zpool create tank mirror c2t0d0 c2t1d0 cache c2t5d0 c2t8d0
zpool create tank raidz2 c2t0d0 c2t1d0 c2t5d0 c2t8d0
https://www.genuinedumps.com/1Z0-580-exam-questions.html
Correct Answer: D
Explanation/Reference:
Creating a ZFS Storage Pool with Cache Devices
You can create a storage pool with cache devices to cache storage pool data. For example:
# zpool create tank mirror c2t0d0 c2t1d0 c2t3d0 cache c2t5d0 c2t8d0
Note:
* Creating a Basic Storage Pool
The following command creates a new pool named tank that consists of the disks c1t0d0 and c1t1d0:
# zpool create tank c1t0d0 c1t1d0
These whole disks are found in the /dev/dsk directory and are labelled appropriately by ZFS to contain
a single, large slice. Data is dynamically striped across both disks.
* Creating a Mirrored Storage Pool
To create a mirrored pool, use the mirror keyword, followed by any number of storage devices that
will comprise the mirror. Multiple mirrors can be specified by repeating the mirror keyword on the
command line. The following command creates a pool with two, two-way mirrors:
# zpool create tank mirror c1d0 c2d0 mirror c3d0 c4d0
QUESTION 7
Your installation has completed successfully and the system did not reboot automatically. Which
option would cause this?
A. Automatic reboots are only allowed when invoked via SMF.
B. The client never reboots automatically after the successful installation, staying available for
manually verification of the install process.
C. The 'auto_reboot' parameter in the Automated Installer manifest has not been set to 'true.'
D. The 'installation' service needed to be refreshed for the 'auto_reboot' setting is to be applied, so
all clients being installed from it could reboot.
E. Post installation reboots are no longer necessary because the Oracle Solaris 11 Automated
Installation installs and actives the system's services in the desired state such that there is no
need for a reboot.
Correct Answer: C
Explanation/Reference:
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
