問題文

A project needs its own isolated network with a subnet and a router to the outside. Which service provides that?

選択肢

1. The dashboard, because networks are created from the web pages, which means a project loses its router the moment it stops using a browser.
2. The compute service, because the network interface of an instance is part of that instance's definition, and the component that owns the definition of the instance is therefore the component that must also own the network to which the interface will eventually be attached.
3. The block storage service, since subnets are allocated from a pool, so an address range and a disk volume are carved out by one and the same component.
4. The networking service, which offers networks, subnets, ports and routers as resources that a project can create for itself.
