Which of the following provides a means of creating virtualized operating system environments within an instance of Solaris?
a) Zones
b) SMF
c) VLANs
d) Subnets
The correct answer is a.

Zones, also known as Solaris Containers, isolate software applications and services using flexible, software-defined boundaries. This approach to virtualization and software partitioning enables you to create many private execution environments within a single instance of the Solaris Operating System.

SMF or Service Management Facility SMF provides an infrastructure that augments the traditional UNIX start-up scripts, init run levels, and configuration files. SMF defines a set of actions that can be invoked on a service by an administrator. These actions include enable, disable, refresh, restart, and maintain.

A Virtual LAN is a collection of network nodes that are the same broadcast domain regardless of their physical location or connection point in the network. A VLAN serves a logical workgroup with no physical barriers and allows users to share information and resources as though located on the same LAN.

A subnet or subnetwork is a division of a network that allows that large network to be broken down into what appears to be several smaller ones that share a common address component. In a TCP/IP network, subnets contain the same IP address prefix.
