In Tableau Server, schedules manage tasks such as extract refreshes and subscriptions. The execution mode of a schedule determines how tasks within that schedule are processed by the Backgrounder process:
* Parallel: Tasks run simultaneously (up to the Backgrounder's capacity), which is the default setting.
* Serial: Tasks run one-at-a-time in sequence, ensuring that one task completes before the next begins.
To ensure tasks associated with a particular schedule run one-at-a-time, you must configure the schedule's execution mode toSerial. This is done in the Tableau Server web interface:
* Go toSchedules.
* Select the schedule, clickActions > Edit Schedule.
* UnderExecution, chooseSerialinstead ofParallel.
* Option A (Set Execution to Serial): Correct. This directly addresses the requirement by forcing tasks to execute sequentially.
* Option B (Set Default priority to 0): Incorrect. Priority (1-100) determines the order of task execution across all schedules, not whether tasks run one-at-a-time within a single schedule. Also, 0 is not a valid priority value (minimum is 1).
* Option C (Set Frequency to Hourly): Incorrect. Frequency (e.g., hourly, daily) controls when the schedule runs, not how tasks within it are executed.
* Option D (Set Execution to Parallel): Incorrect. Parallel execution allows tasks to run simultaneously, which contradicts the requirement.

Tableau Server has specific hardware requirements for production environments to ensure stability and performance. The minimum recommended free disk space for a production installation is50 GB. This accounts for:
* The installation itself (approximately 1-2 GB).
* Space for log files, temporary files, and extracts managed by the File Store and Data Engine.
* Room for backups and operational overhead.
The full minimum hardware recommendations for a single-node production deployment are:
* 8 CPU cores(2.0 GHz or faster).
* 32 GB RAM.
* 50 GB free disk space(on the system drive, typically C: on Windows).
* Option A (32 GB): Incorrect. While 32 GB is the minimum RAM requirement, it's insufficient for disk space in production.
* Option B (50 GB): Correct. This matches Tableau's official recommendation for production environments.
* Option C (15 GB): Incorrect. 15 GB is the minimum for a non-production or trial installation, not production.
* Option D (64 GB): Incorrect. While 64 GB exceeds the minimum, it's not the specified requirement-
50 GB is sufficient.
