To change the NDB GUI password via the CLI, the administrator should use the command era-server > security password reset. This command interacts with the NDB server (referred to as era-server in the CLI context) to reset the password for the GUI admin user. The process typically prompts for the new password and confirmation, ensuring secure password management. This is the supported method for CLI-based password changes in NDB.
Other options are incorrect:
A. sudo passwd era: The passwd command is for Linux user accounts, not NDB-specific GUI credentials.
B. sudo user name admin password: This is not a valid command syntax for NDB CLI.
C. era-server > username admin password: This lacks the correct subcommand (security password reset) and syntax.
Thus, the verified answer is D, aligning with NDB’s CLI security management.
