問題文
A team edits the wireless configuration of a controller over NETCONF from a remote site and wants the device to put the earlier configuration back by itself if the edit cuts the path that manages the device. Which statement describes the mechanism that the protocol offers for that?
選択肢
- A commit that is marked as confirmed is undone by the server unless a plain commit follows it before the timeout of that confirmed commit runs out.
- The earlier configuration is held as the startup configuration by the server so a reboot of the controller is what brings that configuration back.
- A lock taken on the running configuration is dropped by the server when the session ends and dropping that lock puts the earlier configuration back in place.
- A commit is undone by the server as soon as the session that sent it ends so the team has to keep the session open until it trusts the result.
