To force Tableau Server to require the setup of a new administrator account (e.g., resetting the server to an initial setup state), the tsm reset command is the appropriate tool. This command resets Tableau Server’s administrative configuration, including the TSM administrator account, while preserving content like workbooks and data sources.

Option B (Run the tsm reset command): Correct. Running tsm reset clears the current TSM administrator credentials and configuration settings. The next time you access TSM (e.g., via the web interface or CLI), it prompts you to set up a new administrator account, mimicking the initial setup process. Command: tsm reset --username --password .

Option A (Edit tabsvc.yml): Incorrect. The tabsvc.yml file contains service configuration data, but manually editing it is not supported or recommended for resetting the administrator account. It could also corrupt the installation.

Option C (Run the tsm register command): Incorrect. The tsm register command is used to register Tableau Server with a new product key or identity store, not to reset the administrator account.

Option D (Reinstall Tableau Server): Incorrect. Reinstallation wipes the entire server, including content, and is overkill for this task. The tsm reset command achieves the goal without data loss.
