• Question 272:

  You can create _______________ for members in a dimension so that their labels appear differently in the view.

  A. parameters
  B. duplicates
  C. copies
  D. aliases
  D. aliases

  ---

  Explanation/Reference:

  You can create aliases (alternate names) for members in a dimension so that their labels appear differently in the view.

  Aliases can be created for the members of discrete dimensions only. They cannot be created for continuous dimensions, dates, or measures.

  To create an alias:

  

  1) In the Data pane, right-click a dimension and select Aliases.

  2) In the Edit Aliases dialog box, under Value (Alias), select a member and enter a new name.

  

  To submit your changes: In Tableau Desktop, click OK. On Tableau Server or Tableau Online, click the X icon in the top-right corner of the dialog box. When you add the field to the view, the alias names appear as labels in the view. For example:

• Question 273:

  Which of the following is NOT a new feature introduced in Tableau 2020.1?

  A. Dynamic Paramaters
  B. Viz Animations
  C. Buffer Calculations
  D. Set Control
  D. Set Control

  ---

  Explanation/Reference:

  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 2020.1

  For 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.

• Question 274:

  A union of two tables usually results in an

  A. decrease in the number of rows
  B. increase in the number of rows
  C. decrease in the number of columns
  D. increase in the number of columns
  B. increase in the number of rows

  ---

  Explanation/Reference:

  From the official Tableau documentation:

  You can union your data to combine two or more tables by appending values (ROWS) from one table to another. To union your data in Tableau data source, the tables must come from the same connection.

  B. A way to combine table columns in relational databases by using shared values
  C. A way to combine multiple Tableau workbooks using similar data sources
  D. A combination of rows appended from different tables that have the same column names
  A. A combination of columns appended from different tables that have similar values

• Question 278:

  Which of the following is a compelling reason to export a sheet in Tableau to a PDF?

  A. If we want a static view of the visualisation.
  B. If we want to use filters in the visualisation.
  C. If we want to interact with the visualisation.
  D. If we want to dynamically enter parameters to the visualisation.
  A. If we want a static view of the visualisation.

  ---

  Explanation/Reference:

  Exporting the visualisation gives us a static view of the visualisation.

  It is NOT possible to interact with it, use filters, or dynamically enter anything in a visualisation exported PDF.

  In Tableau Desktop, you can save views as PDF files rather than printing them as hard copies. You do not need to have Adobe Acrobat installed on your computer. When you print an individual sheet to PDF, filters in the view are not included.

  To show filters, create a dashboard containing the sheet and export the dashboard to PDF.

  (IMPORTANT)
