1. Question 1

   You are creating a combined axis chart.

   Where should you drag the second measure after dragging the first measure to the Rows shelf?

   AThe Filter card
   

   BThe vertical axis in the view
   

   CThe Marks card
   

   DThe horizontal axis in the view
   

   Correct answer: D

   In Tableau, when creating a combined axis chart, after dragging the first measure to the Rows shelf, you should drag the second measure directly onto the existing axis in the view. This will combine both measures on the same axis, allowing them to share a scale and an axis, which is the essence of a combined axis chart.

   
   

2. Question 2

   Which of the following situations describe the best reason to use a union?

   AYou have two tables with similarly named columns of data that you want to combine.
   

   BYou have two data sets with similar data types for which you want to find only distinct values.
   

   CYou have two tables with differently named columns of data that you want to combine.
   

   DYou have two data sets saved in different formats that you want to unify into a single format.
   

   Correct answer: A

   You should use a union when you have two tables with similarly named columns of data that you want to combine. A union is a method for combining data by appending rows of one table onto another table.The tables that you union must have the same number of fields, the same field names, and the same data types2

   
   

3. Question 3

   BUnion Search
   

   CPattern Search
   

   DWildcard Search

   You can use Wildcard Search to set up search criteria to automatically include tables in your union. Use the wildcard character, which is an asterisk (*), to match a sequence or pattern of characters in the Excel workbook and worksheet names, Google Sheets workbook and worksheet names, text file names, JSON file names, .pdf file names, and database table names.

   When working with Excel, text file data, JSON file, .pdf file data, you can also use this method to union files across folders, and worksheets across workbooks. Search is scoped to the selected connection. The connection and the tables available in a connection are shown on the left pane of the Data source page.

5. Question 5

   True or False:When relating tables, the fields that define the relationships must have the same data type.

   ATrue
   

   BFalse
   

   Correct answer: A

   According to the official documentation, the following are the requirements for using relationships:

   1) When relating tables, the fields that define the relationshipsmusthave the same data type. Changing the data type in the Data Source page does not change this requirement. Tableau will still use the data type in the underlying database for queries.

   2) You can't define relationships based on geographic fields.

   3) Circular relationships aren't supported in the data model.

   4) You can't edit relationships in a published data source.

   5) You can't define relationships between published data sources.

   6) Your workbook must use an embedded data source for you to be able to edit relationships and performance options in the Data Source page in Tableau Online or Tableau Server.
