Which of the following is NOT a new feature introduced in Tableau 2020.1?
Answer(s): D
Your Tableau Desktop Specialist exam will be based on the 2020.1 version. Set controls are a new feature introduced in the 2020.2 version, and hence is the correct answer - it is not a part of 2020.1For the 2020.1 version the new features were:1) Viz animations:Viz animations help you see and understand your changing data. It's easy to track the logical steps behind data's evolution and tell powerful data stories. Sorting, filtering, adding fields, and other actions will now smoothly animate your visualizations. Choose whether to turn Viz Animations on or off, and decide how you'd best like to apply animations to your new workbooks.2) Dynamic Parameters:Say goodbye to republishing workbooks with parameters every time the underlying data changes. Set your parameter once, and Tableau will automatically update the parameter's list of values every time someone opens the workbook.3) Buffer Calculations:Buffer calculations allow you to visualize the distance around point locations. Give Tableau three parameters--location, distance, and a unit of measure--and a buffer, or boundary is instantly created. Answering complex spatial questions becomes easier than ever before--visualize what properties are within 200 meters of a proposed transit site, or how many competitors' stores are within 1 mile of their store, and more.

________________ can only create header. _______________ will create header and axis both.
Answer(s): A
Using the Sample superstore as a reference:1) Let's plot a bar chart showing SUM(Quantity) for each Segment:2) Right click on the x-axis (Segment):Notice we don't have an option to edit the axis, only header. This is because only continous values form the AXIS.3) Similarly, right click on the y-axis (Quantity):Now we have the option to edit BOTH the axis and the header.

______________ is a method for appending values (rows) to tables. You can use this method if both tables have the same columns. The result is a virtual table that has the same columns but extends vertically by adding rows of data.
Unioning is the correct answer!From the official documentation:For example, suppose you have the following customer purchase information stored in three tables, separated by month. The table names are "May2016" , "June2016" and "July2016."

How can you change the Default Aggregation for a measure in Tableau?
According to the official Tableau documentation:Dimensions don't have aggregation properties, and adding properties manually each time defeats the whole DEFAULT aggregation purpose. Window tab doesn't have any default aggregation option!
