Command for Transitioning from Shell Prompt to CLI Prompt

B

The correct answer to this question is "B. cli."

Juniper Networks Junos operating system provides two different modes to interact with the device: the shell prompt and the CLI prompt.

The shell prompt is a basic Unix shell that provides access to the underlying operating system. It allows the user to perform administrative tasks, such as managing files, running scripts, and configuring network interfaces.

The CLI prompt is a Junos-specific interface that provides access to the device's configuration and management features. It is the primary interface for configuring and managing Junos devices.

To switch from the shell prompt to the CLI prompt, you need to use the "cli" command. Once you enter the command, the Junos CLI prompt will appear, and you can start configuring and managing the device.

The other options given as answers are as follows:

A. run cli: This command starts a new instance of the Junos CLI prompt within the current session. This is useful when you need to run multiple CLI sessions simultaneously.

C. start cli: This command starts a new session and logs you into the CLI prompt directly. It is equivalent to using the "cli" command after logging in.

D. edit: This command allows you to enter configuration mode, where you can make changes to the device's configuration. However, it does not switch you to the CLI prompt from the shell prompt.
