Why each option

This question asks to identify three key steps involved in recovering a lost root password on a Junos OS device.

AReboot the device.Correct

Rebooting the device is the initial step in the root password recovery process, typically to enter single-user mode or a special recovery mode. This allows for system access without full authentication.

BRun the recovery script.Correct

Running a recovery script (often `/usr/libexec/ui/cli-recover.sh` or similar, depending on Junos OS version and platform) is a common step during the password recovery process after gaining limited access to reset system parameters or passwords.

CReset the root password.Correct

Resetting the root password is the ultimate goal of the recovery process. Once in recovery mode and having run the necessary scripts, the administrator will set a new password for the root user.

DReset the user passwords.

Resetting all user passwords is not an inherent part of *root* password recovery; only the root password needs to be reset.

ELoad factory-default configuration.

Loading the factory-default configuration would erase all configurations, which is an extreme measure and not typically part of *just* a root password recovery unless configuration loss is acceptable or intended for other reasons.
