Selected Answers: A


The correct option is ✅ A. Run tmsh create auth user username prompt-for-password from bash.
The recommended and supported method for creating a new local user on a BIG-IP system via the Command Line Interface (CLI) is using the TMOS Shell (tmsh). Using tmsh ensures that the user is correctly added to the system configuration and the appropriate security files, such as /config/bigip/auth/localusers.
Explanation
Command Syntax: The standard syntax for this operation is tmsh create /auth user <username> ... prompt-for-password. This method securely prompts the administrator for the new user's password rather than requiring it to be entered in plain text.
Integration: Creating users through tmsh automatically handles partition access, roles, and shell assignments, ensuring the user is recognized by the BIG-IP management plane.
