問題文
A supplier delivers a function that is made of four virtual machines with links between them. The team asks how the reference model names that whole delivery. Which answer names it?
選択肢
- It is four virtual network functions because each machine is managed on its own by the function manager of the site.
- It is one virtual network function that exposes its behavior through the external connection points that it declares.
- It is one physical network function because the machines are pinned to the hosts that hold the right adapters.
- It is one network service because the links between the machines make it a composition rather than a single function of the site.
