Which command would you use to display the current configuration hierarchy on a Junos device?

The command to display the current configuration hierarchy on a Junos device is "show configuration". This command effectively provides a structured view of the device's configuration, allowing network administrators to understand the various settings and how they are organized hierarchically.

Using this command gives you not only the individual configuration settings but also an insight into the organization of those settings within the device's hierarchy. This hierarchical structure is essential for managing and troubleshooting configurations, as it allows users to see how different elements are nested and related to each other.

The other options don't align with the correct syntax or commands used in Junos. "Display configuration" and "view configuration" do not exist as recognized commands for achieving this task in Junos OS. "Show running-config" is a common command in other routing systems but is not applicable in Junos, as it utilizes different terminology and a different command set. Thus, "show configuration" is the appropriate and accurate command for displaying the current configuration hierarchy in Junos devices.
