Which action solves the error shown in the exhibit?

Suggested Answer: B Vote an answer

The error message in the exhibit indicates that the root-authentication statement is missing, which is mandatory for committing the configuration. In Junos OS, it is required to set a password for the root account to commit any configuration changes. This is a security measure to ensure that unauthorized users cannot access the device's configuration mode. To solve the error shown in the exhibit, configuring a password for the root account is necessary. This can be done by using theset system root-authentication plain-text-password command, after which the user will be prompted to enter a new password for the root account.
