問題文

An engineer wants to run familiar command line tools directly on a Nexus switch. What do the shell environments on the switch provide?

選択肢

1. A restricted mode in which the switch accepts configuration only from a signed script, so the engineer has to sign every change before it is applied.
2. A place on the switch in which the ordinary tools and scripts can run, so that no host outside of it has to be involved.
3. A converter that turns the output of the switch commands into a structured document, so an external program can read it without any parsing of its own.
4. A remote session to a management host that holds the tools, so the engineer works on that host and the switch only forwards the keystrokes to it.
