Oracle Cloud Infrastructure

Overview

* Flexible cloud infrastructure supports dynamic resource pooling, elastic scalability, and rapid application deployment

* Includes Oracle Enterprise Manager, a complete cloud lifecycle management solution that allows you to quickly set up, manage, and support enterprise clouds and traditional Oracle IT environments from applications to disk

* Built-in security and high availability

* Application-aware virtualization and management capabilities

Answer : C

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.

Answer : A, C

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.

Answer : C, E

E:

* Many configuration tasks around name services have moved into the SMF in Solaris 11.

* The Service Management Facility (SMF), first introduced in Oracle Solaris 10, is a feature of the operating system for managing system and application services, and it replaces the legacy init scripting start-up mechanism common to prior releases of Oracle Solaris and other UNIX operating systems. SMF improves the availability of a system by ensuring that essential system and application services run continuously even in the event of any hardware or software failures. SMF is one of the components of the wider Oracle Solaris Predictive Self Healing capability.

Note:

* In Oracle Solaris 11, certain aspects of system configuration have changed, including the migration of several system, network, and naming services configuration to SMF.

Answer : B, E

B (not C): A zone is a virtualized operating system environment that is created within a single instance of the Oracle Solaris operating system. Oracle Solaris Zones are a partitioning technology that provides an isolated, secure environment for applications.

Note:

* When you create a zone, you produce an application execution environment in which processes are isolated from the rest of the system. This isolation prevents a process that is running in one zone from monitoring or affecting processes that are running in other zones. Even a process running with root credentials cannot view or affect activity in other zones. A zone also provides an abstract layer that separates applications from the physical attributes of the machine on which the zone is deployed. Examples of these attributes include physical device paths and network interface names. The default non-global zone brand in the Oracle Solaris 11.1 release is the solariszone.

By default, all systems have a global zone. The global zone has a global view of the Oracle Solaris environment that is similar to the superuser (root) model. All other zones are referred to as non-global zones. A non-global zone is analogous to an unprivileged user in the superuser model. Processes in non-global zones can control only the processes and files within that zone. Typically, system administration work is mainly performed in the global zone. In rare cases where a system administrator needs to be isolated, privileged applications can be used in a non-global zone. In general, though, resource management activities take place in the global zone.
