Which two statements are true about the rescue configuration file? (Choose two.)
Click on the arrows to vote for the correct answerA. B. C. D.
The Junos OS provides a feature called rescue configuration, which allows you to boot the router or switch into a minimal configuration mode that contains only basic services and interfaces. In this mode, you can access the device's file system and correct any configuration problems that might be preventing the device from functioning correctly.
Regarding the statements given in the question, here is an explanation of each option:
A. It must include a root password: This statement is false. The rescue configuration file is a minimal configuration that is designed to provide a bare minimum configuration that is enough to access the device and make any necessary corrections. It does not require a root password, and you can log in to the rescue configuration without a password.
B. It is rollback file number 50, and you can recover it by issuing rollback 50: This statement is true. When you save the rescue configuration, it is stored as a file called rescue.conf.gz in the /config directory. The rescue configuration is automatically assigned to rollback number 50, so you can recover it by issuing the rollback 50 command.
C. It is created by issuing request system configuration rescue save: This statement is true. To create a rescue configuration, you can issue the request system configuration rescue save command. This command creates a minimal rescue configuration file that contains the basic settings required for the device to boot up and function.
D. It is updated automatically when you commit: This statement is false. The rescue configuration file is a separate file that is not automatically updated when you commit changes to the active configuration. You must manually save the rescue configuration whenever you make changes that affect the device's ability to boot up or function correctly.
In summary, the two true statements about the rescue configuration file are that it is created by issuing request system configuration rescue save and that it is rollback file number 50, and you can recover it by issuing rollback 50.
