Oracle 1Z0-820 PDF Exam Questions:

The framework enables providers of cryptographic services to have their services used by many consumers in the Oracle Solaris operating system. Another name for providers is plugins. The framework allows three types of plugins:

* User-level plugins - Shared objects that provide services by using PKCS #11 libraries, such as pkcs11_softtoken.so.1.

* Kernel-level plugins - Kernel modules that provide implementations of cryptographic algorithms in software, such as AES.

Many of the algorithms in the framework are optimized for x86 with the SSE2 instruction set and for SPARC hardware.

* Hardware plugins - Device drivers and their associated hardware accelerators. The Niagara chips, the ncp and n2cp device drivers, are one example. A hardware accelerator offloads expensive cryptographic functions from the operating system. The Sun Crypto Accelerator 6000 board is one example.

A: + Indicates the file/directory was added in the later dataset

C: R Indicates the file/directory was renamed in the later dataset

E: - Indicates the file/directory was removed in the later dataset

G: M Indicates the file/directory was modified in the later dataset

Note: Identifying ZFS Snapshot Differences (zfs diff)

You can determine ZFS snapshot differences by using the zfs diff command.

The following table summarizes the file or directory changes that are identified by the zfs diff command.

File or Directory Change Identifier

* File or directory is modified or file or directory link changed

M

* File or directory is present in the older snapshot but not in the newer snapshot

---

* File or directory is present in the newer snapshot but not in the older snapshot

+

* File or directory is renamed

R

A: If the network is setup to perform automated installations, you can perform a text installation over the network by setting up an install service on the network and selecting a text installation when the client system boots.

B: After a fresh install of Solaris 11 express, only the console mode is activated.

To add Gnome, simply do :

$ sudo pkg install slim_install

This will install additional packages that are not installed by default.

D: The text installer advantages over the GUI installer include:

* In addition to modifying partitions, the text installer enables you to create and modify VTOC slices within the Solaris partition.

F: How do I upgrade my Solaris 10 or lower systems to Solaris 11?

Unfortunately, you CAN'T. There is no direct upgrade installer or other tool that will allow you to upgrade from earlier releases of Solaris to Solaris 11. This is primarily due to the vast changes in the packaging mechanism in Solaris 10.

Incorrect answers:

E: Both installers can be used to install Oracle Solaris on the x86 platform. The text installer can also be used to install Oracle Solaris on the SPARC platform.

G: Both installers enable you to select, create, or modify disk partitions during an installation.

H: Both installers can be used to install Oracle Solaris on the x86 platform. The text installer can also be used to install Oracle Solaris on the SPARC platform.

Use the installadm set-criteria command to update the client criteria associated with an AI manifest that you already added to a service using installadm add-manifest.

Use the installadm add-manifest command to add a custom AI manifest to an install service.

The value of manifest is a full path and file name with .xml extension. The manifest file contains an AI manifest (installation instructions). The manifest file can also reference or embed an SC manifest (system configuration instructions).

Incorrect answers:

A: The sys-unconfig command is used to restore a system's configuration to

an 'as-manufactured' state, ready to be reconfigured again.

C: You can use the sysconfig create-profile command to create a new system configuration profile. Thesysconfigcommand affects all functional groupings in the Solaris instance.

D: Use the installadm create-profile command to add a system configuration profile to an install service. The create-profile subcommand validates profiles before adding them to the install service.

Specify criteria so that appropriate clients select that configuration profile. If no criteria are specified, all clients use this profile.

* (Not A, B, C): interval (here 10 seconds): Specifies the length in seconds to pause between each interval report.

* duration (here 24 h)

* -R report[,report] (here high)

Print a summary report.

high Print a summary report detailing the highest usage of each resource and zone during any interval of thezonestatutility invocation.

Note: The zonestat utility reports on the cpu, memory, and resource control utilization of the currently running zones. Each zone's utilization is reported both as a percentage of system resources and the zone's configured limits.

The zonestat utility prints a series of interval reports at the specified interval. It optionally also prints one or more summary reports at a specified interval.

The default output is a summary of cpu, physical, and virtual memory utilization. The -r option can be used to choose detailed output for specific resources.
