You have been tasked with creating a dedicated virtual network between two local zones within a single system. In order to isolate the network traffic from other zones on that system. To accomplish this, you will create__________.

An etherstub is a pseudo-ethernet Network Interface Card (NIC) configured at the data link layer (L2) in Oracle Solaris 11. It acts as a virtual switch that is completely isolated from the physical network interfaces of the system. By creating an etherstub and configuring Virtual Network Interfaces (VNICs) over it for specific local zones, administrators can establish a dedicated, isolated virtual network for inter-zone communication. This ensures that the network traffic between these zones is not exposed to the external network or to other zones on the system.

Incorrect B: Solaris does not use a "virtual router" construct for L2 isolation between zones; routing implies Layer 3 operations, not isolated Layer 2 switching. Incorrect C: While an etherstub functions conceptually like a virtual switch, the specific Solaris administrative object created via dladm create-etherstub is explicitly called an etherstub. Incorrect D: A virtual bridge connects multiple links together but does not inherently create an isolated internal-only network like an etherstub does. Incorrect E: A VNIC connects a zone to a network, but without an etherstub, it would connect to a physical link, lacking the required isolation. Incorrect F: Virtual switches are created implicitly over physical links, but for completely isolated traffic, an etherstub must be explicitly created by the administrator.
