Tableau Desktop Specialist — Question 94

A Data Analyst needs to update an existing dashboard. The current dashboard shows financial results data, and users have asked for a comparison of budgets to be added to the dashboard. A new data source has been created that includes both the actual costs and budgets and was published to the corporate Tableau site.

How should the analyst update the existing dashboard?

Answer options

• A. Create a new workbook in Tableau Desktop and connect to the new data source. Copy and paste all the tabs from the old workbook into the new one.
• B. Create a copy of the existing workbook, open it in Tableau Desktop, and connect to the new data source. Update each sheet, using fields from the new data source.
• C. Edit the existing workbook on the Tableau site and connect to the new data source. From the Data menu, choose Replace Data Source.
• D. Edit the existing workbook on the Tableau site and connect to the new data source. Blend the new data source with the existing data source.

Correct answer: C

Explanation

The correct answer is C because replacing the data source within the existing workbook allows for a seamless update without needing to recreate the dashboard. Options A and B require unnecessary duplication of work, while D suggests blending data sources, which is not needed if the new data source can directly replace the old one.
