By default, Tableau Server is configured to allow data-driven alerts. The server-wide setting dataAlerts.enabled is set to true by default. Furthermore, when a new site is created, the site-level setting "Let users create and receive data-driven alerts" is also enabled by default. Since the scenario specifies that both the Tableau Server installation and the site use default settings, no additional configuration is necessary for users to begin setting up data-driven alerts.

A. This is incorrect because data-driven alerts are enabled by default at the server level in TSM. No action is required on the configuration page.

B. This command configures the frequency at which Tableau Server checks for alert conditions, it does not enable the feature itself. The default interval is already 60 minutes.

C. This is incorrect because the data-driven alerts setting is enabled by default on a new site's Settings page. A change would only be necessary if it were manually disabled.

1. Tableau Server Help - Set Up for Data-Driven Alerts.

Reference: In the section "Enable data-driven alerts (server-wide setting)", the documentation states: "By default, data-driven alerts are enabled."

Reference: In the section "Control data-driven alerts (site-level setting)", it states: "Go to a site's Settings page... Under Data-Driven Alerts, clear or select Let users create and receive data-driven alerts. By default, this option is selected."

2. Tableau Server Help - tsm configuration set Options.

Reference: The documentation for the key dataAlerts.enabled specifies its default value is true.

Reference: The documentation for the key dataAlerts.checkIntervalInMinutes specifies its default value is 60. This confirms that option B does not change the default behavior and is not an enabling step.
