Exam JN0-104 topic 1 question 31 discussion

The "help topic interface ?" command, when entered in Junos OS, will provide a list of available options related to the "interface" command and a brief description of their usage guidelines. Option B is correct: It displays the available options and a brief description of their usage guidelines. This information helps users understand the different parameters and arguments that can be used with the "interface" command and provides guidance on how to use them effectively. It does not display the best options based on the current configuration (option A). Additionally, it does not provide the administration manual for the interface command (option C) or usage examples for the top-ten interface commands (option D). So, the correct answer is B: It displays the available options and a brief description of usage guidelines.
