At ValidExamDumps, we consistently monitor updates to the Oracle 1Z0-580 exam questions by Oracle. Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. 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Other certification materials providers often include outdated or removed questions by Oracle in their Oracle 1Z0-580 exam. These outdated questions lead to customers failing their Oracle Solaris 11 Installation and Configuration Essentials exam.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.
Which three ZFS options may be combined to provide zones storage with data security and a minimal storage footprint?
A:
* Oracle Solaris 11 adds transparent data encryption functionality to ZFS. All data and file system metadata (such as ownership, access control lists, quota information, and so on) are encrypted when stored persistently in the ZFS pool.
* A very simple example of using ZFS encryption is as follows:
# zfs create -o encryption=on rpool/export/project
Enter passphrase for 'rpool/export/project':
Enter again:
# zfs create rpool/export/project/A
# zfs create rpool/export/project/A/design
# zfs create rpool/export/project/B
D: compression=on reduces storate footprint
E: If you want to allow the filesystem to be managed inside the zone, use the zfs zoned=on option when creating or modifying the filesystem.
What physical devices will be used in sequence to boot the system, given the following output?
Note:
* second line in exhibit (minor typo):
boot-device = disk net
*The line starting with net is:
/pci@780/pci@0/pci@1/network@0
Which two statements are true of the GRUB menu?
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.
Which service must be enabled in order to create an iSCSI LUN?
How to Enable the STMF Service
COMSTAR uses SMF to store its current, persistent configuration, such as logical unit mapping, host group definitions, and target group definitions. When the service is enabled during boot or when using the svcadm command, it clears any stale configuration data inside the kernel framework, and then reloads the configuration from the SMF repository into the driver.
The COMSTAR target mode framework runs as the stmf service. By default, the service is disabled. You must enable the service to use COMSTAR functionality. You can identify the service with the svcs command. If you have not rebooted the server since installing the group/feature/storage-server package, the service might not be enabled correctly.
Note:
* You can set up and configure a COMSTAR Internet SCSI (iSCSI) target and make it available over the network. The iSCSI features can work over a normal Internet connection (such as Ethernet) using the standard iSCSI protocol. The iSCSI protocol also provides naming and discovery services, authentication services using CHAP and RADIUS, and centralized management through iSNS.
