The command used to display the interface status and statistics on a JUNOS device is “show interfaces.” This command provides detailed information about each interface on the device, including its current operational status, whether it is up or down, traffic statistics such as input and output bytes, error counts, and additional attributes relevant to each interface.

In contrast, the other options do not represent valid commands in JUNOS. “display interface” is not recognized in the JUNOS environment, as JUNOS does not utilize the term "display" for command functionalities. “show status” would not provide the detailed interface statistics a network administrator needs; instead, it typically pertains to the overall status of the device rather than specifics on interface details. Lastly, “view interfaces” is also not a recognized command in JUNOS syntax, as it does not follow the standard command structure used within the operating system.

Thus, “show interfaces” is the accurate command for retrieving comprehensive and specific information about interfaces on a JUNOS device.
