問題文

An operator must state the relationship between the declarative command line and the programmatic interface of the switch operating system. Which statement is correct?

選択肢

1. The programmatic interface covers only the monitoring operations, because exposing the configuration operations to an unattended caller would allow a change to be made without the pending and apply stages that the command line enforces and the vendor has therefore left them out of it deliberately.
2. The command line covers only a subset, because some objects can be configured only through the programmatic interface, and the rest are shared.
3. They use different object models, so the two views of the same switch can diverge until an operator reconciles them by hand from one side or the other.
4. They are equivalent in functionality, so every management operation can be run from either one.
