You have the following data source in tableau Server.

You need to ensure that the data is updated every hour.
What should you select?
To ensure that the data is updated every hour on Tableau Server, you would need to go to the 'Extract Refreshes' option. Here, you can schedule the data extracts to refresh at the desired frequency, which in this case would be every hour.
You have the following chart that shows the cumulative of sales from various dates.

You want the months to appear as shown in the following chart.

What should you do?
To ensure the dates are shown in a continuous axis, you should convert the date to a continuous field. This will display the months in a sequence without any breaks, which is needed for showing a trend over time like the cumulative sum of sales.
You have a workbook that connects to a database. The database requires authentication.
You plan to publish the workbook and schedule a daily refresh of the data.
Which two conditions must be met to schedule the refresh? Choose two.
To schedule a refresh of the data, you need to ensure that Tableau Server or Tableau Online can access the database without prompting for credentials. This can be done by embedding the credentials in the workbook or the published data source. You also need to extract the data from the database and publish it as a separate data source or as part of the workbook. A live connection would not allow you to refresh the data on a schedule, as it would always query the database directly. A hyper file is a format for storing extracted data, but it is not a requirement for scheduling a refresh.Reference:

You want to show the cumulative total of each year for every state.

The following is a sample of the data.

You want to improve the performance of the views by including only animals of a particular type.
To which filter should you add the Type field on the worksheet?
