1z0-580 Oracle Solaris 11 Installation and Configuration Essentials - Practice Questions

Question 1

A customer has multiple applications and you believe consolidation using Oracle Solaris Zones will help them. The customer is concerned that consolidating them all on one physic server may cause adverse interactions between them, causing problems with functionality, security, and performance. What are the two benefits of Zones that would explain why Zones would be a good choice?

○
better single threaded performance
○
better software isolation
○
better hardware isolation
○
simpler VLAN management
○
simple, effective resource controls

Reference / correct answer:

better software isolation

simple, effective resource controls

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 nonglobal 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.

Question 2

Name three Items that illustrate the business value of an integrated stack approach.

Select all that apply, then click Submit answer.

○
The integrated stack method of product development optimizes performance.
○
Multiple products from multiple vendors add up to an easier support structure and less fingerpointing when issues arise.
○
Support and implementation issues are minimized with an integrated stack.
○
An integrated stack will help to deliver faster innovation.
○
To a smaller customer an integrated stack means that they need to purchase everything from one vendor.

Reference / correct answer:

The integrated stack method of product development optimizes performance.

Support and implementation issues are minimized with an integrated stack.

An integrated stack will help to deliver faster innovation.

Incorrect:

Not B: With a single vendor providing all the elements for an application platform, finger pointing is eliminated and problem resolution takes less time.

Note:

* Oracle’s product research and engineering expertise spans the entire stack — from storage, networks, compute and operating systems, to middleware, enterprise applications and databases — and isintegrated and validated to work together to take the guesswork out of deploying complex solutions.

* Oracle is the only high technology company with all the software and hardware components to deliver an infrastructure that can transform and streamline business operation. Indeed, Oracle’s application-to-disk stack is so well integrated and tuned that it provides less risk, better performance, and easier management for application environments.

* Oracle’s end-to-end solution stack includes Oracle’s innovative servers and storage systems, the industry’s only end-to-end virtualization portfolio, robust Oracle Solaris and Oracle Linux operatingenvironments, Oracle Database, middleware, premier enterprise applications, and industry-leading management tools. For years, Oracle has strived to integrate, test, and certify these technologies to work together to deliver the functionality, performance, security, and reliability companies can depend on to get the job done.

* The Oracle integrated stack.
