A. B. C. D.A
You can get the information from "show interface <interface_name> extensive"
The correct answer to the question is option A: "show interfaces fe-0/0/0 extensive." This is a valid command that allows you to view the status of a specific interface on a Juniper Networks router.
The "show interfaces" command is used to view information about the interfaces on a router, including their operational status and configuration settings. By specifying the interface name, you can view detailed information about that specific interface.
The "extensive" keyword provides additional detailed information about the interface, including error statistics, packet counts, and traffic statistics. This information can be useful for troubleshooting connectivity or performance issues.
Option B, "show interfaces fe-0/0/0 status," is not a valid command. The correct syntax for viewing the status of an interface would be "show interfaces fe-0/0/0 terse" or "show interfaces terse | match fe-0/0/0."
Option C, "show interfaces fe-0/0/0 health-info," is also not a valid command. The "health-info" keyword is not a valid option for the "show interfaces" command.
Option D, "show interfaces fe-0/0/0 verbose," is also not a valid command. The "verbose" keyword is not a valid option for the "show interfaces" command. However, the "detail" keyword can be used to provide additional information about the interface configuration and operational status.
