In which scenario would a network administrator most likely need to perform root password recovery on a Junos device?

The device is running out of disk space

The device needs to be moved to a different data center

The device has a hardware failure and needs to be replaced

The previous administrator left the company without providing the root password

After clearing the root password on a Juniper EX4300 switch, the administrator reboots the device. The switch comes up normally, but the administrator wants to verify that the password recovery was successful. What is the most direct way to verify this?

Check the system log for recovery messages.

Run 'request system reboot' again to ensure the configuration is saved.

Run 'show configuration | display set' and look for the root-authentication statement.

Log in as root with a blank password.

A network engineer is attempting to recover the root password on a Juniper vMX virtual router. The engineer has console access and is trying to interrupt the boot process by pressing the Space bar, but the device boots normally. What is the most likely reason for this failure?

The Space bar must be pressed before the device is powered on.

The Space bar is not supported on virtual platforms; only physical devices support password recovery.

The engineer must use the 'boot -s' command from the Junos CLI to enter single-user mode.

The vMX platform uses a different boot loader and requires a different key to interrupt the boot process.

After booting into single-user mode on a Junos device, what is the first step to mount the root file system?

Run the 'show system storage' command

What is the purpose of the 'recovery' boot option on some Junos platforms?

To load the previous configuration file

To perform a full system backup

To boot into a special recovery environment for password reset
