What are the two benefits of Zones that would explain why Zones would be a good choice?

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?

A.
better single threaded performance

B.
better software isolation

C.
better hardware isolation

D.
simpler VLAN management

E.
simple,effective resource controls

Explanation:
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 nonglobal 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.
