Tableau TDS-C01 Online Questions & Answers

• Question 131:

  When is an axis created for the visualisation in Tableau?

  A. When we drag a measure to the row/column shelf
  B. When we drag a dimension to the row/column shelf
  C. When we drag a discrete field to the row/column shelf
  D. When we drag a continuous field to the row/column shelf
  D. When we drag a continuous field to the row/column shelf

  ---

  Explanation/Reference:

  An Individual Axis in Tableau is obtained by adding a continuous into Rows or Columns Shelf.

  Example:

  In order to show Individual Axis in Tableau First, we drag and drop the Color from Dimension shelf to Column Shelf. Next, we drag and drop the Sales Amount from measures shelf to Rows Shelf. Since it is a continuous value, the Sales

  Amount will be aggregated to default Sum. Once you drag them, following Chart report will be generated.

  

  Next, we drag and Drop one more measure value, i.e., Total Product Cost from Measures Region to Rows Shelf. Because it is a Measure value, Total Product Cost is aggregated to default Sum. From the below screenshot, you can observe that Tableau has created an individual axis for each measure (continuous field).

• Question 133:

  Which of the following is true about 'Incremental refresh' when creating Extracts in Tableau?

  A. It only adds rows that are new since the previous refresh.
  B. There is no difference, both are the same when using extracts. They are different when using live connections.
  C. It replaces all of the contents in the extract
  D. They can only be used with large datasets
  A. It only adds rows that are new since the previous refresh.

  ---

  Explanation/Reference:

  Extracts are saved subsets of data that you can use to improve performance or to take advantage of Tableau functionality not available or supported in your original data. When you create an extract of your data, you can reduce the total

  amount of data by using filters and configuring other limits. After you create an extract, you can refresh it with data from the original data.

  When refreshing the data, you have the option to either do a full refresh, which replaces all of the contents in the extract, or you can do an incremental refresh, which only adds rows that are new since the previous refresh.

• Question 134:

  You have a visualization that uses multiple types of sorting. How can you clear all sorting of the visualization?

  A. From the Dashboard menu, select Clear.
  B. Right-click a sorted field, and then select Clear Sort.

• Question 135:

  Using the CoffeeChain table, create a scatter plot of Profit (x-axis) vs Sales (y-axis) broken down by State. Add a Linear trend line to the view. What is its R-squared value?

  A. 0.783262
  B. 0.739284
  C. 0.759329
  D. 0.748472
  A. 0.783262

  ---

  Explanation/Reference:

  Trend lines have become popular questions in recent Tableau examinations. Follow along: 1) First drag Sales to the Rows shelf and Profit to the Columns shelf:

  

  You will only see a single mark since the view is aggregated.

  2) Now, break down this view by state. Drag State into Detail on the Marks shelf ( or directly to the view):

  

  3) Finally, move to the Analytics pane, and drag Trend line to the view. When you drag it, select the Linear option!:

  

  4) The following is our view. Hover over the trend line to see the R-squared value:

  

• Question 136:

  A ________________ is a single zip file that contains a workbook along with any supporting local file data and background images. This format is the best way to package your work for sharing with others who don't have access to the original data.

  A. .twbx file
  B. .tbm file
  C. .twb file
  D. .tde file
  A. .twbx file

  ---

  Explanation/Reference:

  According to the official Tableau documentation:

  Tableau packaged workbooks have the .twbx file extension. A packaged workbook is a single zip file that contains a workbook along with any supporting local file data and background images. This format is the best way to package your work for sharing with others who don't have access to the original data. For more information, see Packaged Workbooks.

• Question 137:

  You need to uniformly change the size for all marks in a view. What should you do?

  A. Use the Fit dropdown menu on the toolbar
  B. Select Format on the menu, and then select Cell Size
  C. Select Size on the Marks card and use the slider to adjust the size
  D. Select Label on the Marks card and then select Alignment
  C. Select Size on the Marks card and use the slider to adjust the size

• Question 138:

  You have a data set that builds a union between two tables. You need to extract the data set.

  What should you use to extract the data set?

  A. physical tables that use a single table extract
  B. physical tables that use multiple table extracts
  C. logical tables that use a single table extract
  D. logical tables that use multiple table extracts
  B. physical tables that use multiple table extracts

• Question 139:

  Which of the following sets would you use to compare the members?

  A. None of these
  B. Dynamic Sets
  C. Static Sets
  D. Combined Sets
  D. Combined Sets

  ---

  Explanation/Reference:

  You can combine two sets to compare the members. When you combine sets you create a new set containing either the combination of all members, just the members that exist in both, or members that exist in one set but not the other. Combining sets allows you to answer complex questions and compare cohorts of your data. For example, to determine the percentage of customers who purchased both last year and this year, you can combine two sets containing the customers from each year and return only the customers that exist in both sets. To combine two sets, they must be based on the same dimensions. That is, you can combine a set containing the top customers with another set containing the customers that purchased last year. However, you cannot combine the top customers set with a top products set.

• Question 140:

  What do the colours Blue and Green represent in Tableau?

  A. Discrete and Continuous
  B. Measures and Dimensions
  C. Continuous and Discrete
  D. Dimensions and Measures
  A. Discrete and Continuous

  ---

  Explanation/Reference:

  Important question! If you selected Dimension and Measure, don't worry! It is a very common mistake. But we're here to learn aren't we?

  When you connect to a new data source, Tableau assigns each field in the data source as dimension or measure in the Data pane, depending on the type of data the field contains. You use these fields to build views of your data.
