Which command-line interface is used to configure Junos devices?

The Juniper Command Line Interface (CLI) is the primary interface used to configure Junos devices. This technology provides a powerful and flexible environment for network engineers to interact with device configurations, manage network operations, and troubleshoot issues. The Juniper CLI allows access to all of the command set needed for configuring or monitoring a Junos device, making it an essential tool for professionals who need to implement and maintain network infrastructures.

Other interfaces, such as the Web CLI and J-Web CLI, provide additional options for accessing and managing devices but may not support the full array of configuration capabilities that the Juniper CLI offers. The Command Line Screen, while it may refer to an aesthetic aspect of the interface, does not denote a separate configuration tool or method within Junos. Therefore, the use of the term "Juniper CLI" encapsulates the core method for device configuration effectively.
