Which two statements describe the result when you enter ?

The Junos Command Line Interface (CLI) is designed with an intuitive, context-sensitive help system that assists users in navigating the command hierarchy. When an administrator enters a question mark (?) at the prompt, the CLI provides immediate feedback based on the current location within the hierarchy. First, it lists all available commands and options that are valid at that specific point. This allows the user to see the breadth of possible next steps without needing to refer to external documentation.

Second, the ? character triggers the display of summary information for each of those commands and options. This brief descriptive text provides a clinical overview of what each command achieves, helping the user select the appropriate tool for their task. This " help-on-demand " feature is functional in both operational and configuration modes. It is important to distinguish this from the help command; while help (such as help topic or help reference) provides more exhaustive documentation and usage examples, the ? prompt is primarily a quick-reference tool for command completion and syntax discovery. This mechanism ensures that even complex configurations can be built accurately by exploring the available options and their summarized purposes directly within the terminal environment.
