You need to configure three zones.
Identify the correct requirement.
A. zone1 will need a VNIC to connect to a physical Ethernet link.
B. zone1 will need at least two VNICs.
C. zone2 and zone3 will need a dedicated etherstub.
D. One etherstub will be necessary.
E. A flow is needed to filter HTTP requests to zone1.
Correct Answer: C
Explanation/Reference:
Explanation:
Note:
* In Oracle Solaris 11, etherstubs and VNICs are the basic components of network virtualization.
* The VNIC connects the virtual network to the external network. The VNIC also enables the zones to communicate with one another through the virtual switch that is automatically created with the VNIC. For a virtual network to host traffic internally between zones and with the external LAN and the Internet, each zone must have its own interface. Therefore, you must repeat this procedure as many times as the number of zones that will belong to the virtual network.
* Create the etherstub.
# dladm create-etherstub etherstub
Perform this step only if you are creating a private virtual network which you want to restrict from being accessed by external systems.

I think this question should be:
You need to configure three zones
zone1 will run an HTTP server, zone2 an application server, and zone3 a database.
zone1 must be accessible to clients on other systems.
zone2 and zone3 must not be accessible to the outside world.
zone2 and zone3 must also communicate without going through zone1.
Identify the correct requirement.
For the above answer would be: C
Given the blunt requirements of the task, don’t see how the correct answer can be selected. A,B,C or D each have their use cases, but as a more general approach C or D would fit better.
