Explanation/Reference:
C: When you assign a network to a global zone, you must define the mode of the network, either Shared IP or Exclusive IP:
In Shared IP mode, the network interface is used by more than one zone. You define the network interface when you you assign the global zone to the network.
In Exclusive IP mode, the network interface is dedicated to the zone. An exclusive network must be declared for the global zone when you assign network to the global zone. Then you configure the IP configuration for the non-global zone.
Not B: There is no command dladm disable to disable a network interface.
Not D: There is no command netconfig disable to disable a network interface.
