  A. Measure Names

  B. Number of Records

  C. Measure Values

• Question 82:

  What is a story point in Tableau?

  A. A single worksheet or dashboard

  B. A collection of dashboards

  C. A collection of both worksheets and dashboards

  D. A collection of worksheets

  Correct Answer: A

  In Tableau, a story is a sequence of visualizations that work together to convey information. You can create stories to tell a data narrative, provide context, demonstrate how decisions relate to outcomes, or to simply make a compelling case.

  A story is a sheet, so the methods you use to create, name, and manage worksheets and dashboards also apply to stories (for more details, see Workbooks and Sheets). At the same time, a story is also a collection of sheets, arranged in a

  sequence. Each individual sheet (worksheet or dashboard) in a story is called a story point.

  When you share a story--for example, by publishing a workbook to Tableau Public, Tableau Server, or Tableau Online--users can interact with the story to reveal new findings or ask new questions of the data.

• Question 83:

  Join the Geo Data and Time Series Table on the Item Number ID column, and display the Store count for every State on a Map. What was the Store count in 2017 for Texas (TX)?

  A. 592,593

  B. 293,202

  C. 416,702

  D. 336,908

  Correct Answer: C

  Since you need BOTH State and the YEAR, we need to use an Inner Join.

• Question 84:

  You may create a context filter to:

  A. To create a dependent filter

  B. Improve performance

  C. To replace a data source filter

  D. Create a dependent numerical or top N filter

  Correct Answer: BD

  Important question! You cannot use a context filter to replace a data source filter since each filter type has its own use case. Also, a content filter is an Independent filter and all other filters are called dependent since they only process the data that passes through a context filter.

  According to the official documentation : Reference: https://help.tableau.com/current/pro/desktop/en-us/filtering_context.htm

• Question 86:

  Using the cwurData table, create a cross-tab showing the number of Publications per Country broken down by Institution, and filtered by Country to only show United Kingdown (UK). For the University of Manchester, what percent of the total publications were contributed in 2014?

  A. 28.415%

  B. 23.497%

  C. 25.683%

  D. 22.404%

  Correct Answer: D

  Phew! Tricky one for sure. This question tests multiple concepts and will help you revise them. We'll be using filters, as well as quick table calculations (percent of total) for this one. 1) Firstly, let's drag Country and Institution to the Rows shelf, and year (discrete) to the Columns shelf. Then, drag Publications to the Text Icon in the Marks Shelf. The following is our view:

  

• Question 87:

  True or False: A reference line cannot be added from the Analytics Pane

  A. True

  B. False

  Correct Answer: B

  You can add a reference line to any continuous axis in the view.

  To add a reference line:

  Drag Reference Line from the Analytics pane into the view. Tableau shows the possible destinations. The range of choices varies depending on the type of item and the current view.

  In a simple case, the drop target area offers three options:

• Question 88:

  What is the minimum amount of RAM recommended for any production use of Tableau Server?

  A. 8GB

  B. 16GB

  C. 32GB

  D. 64GB

  Correct Answer: B

  The computer on which you are installing or upgrading Tableau Server must meet the minimum hardware requirements. If the Setup program determines that your computer does not meet the following requirements, you will not be able to install Tableau Server. These minimum requirements are appropriate for a computer that you use for prototyping and testing of Tableau Server. They apply to single-node installations and to each computer in a distributed installation.

• Question 89:

  What is the one critical difference between normal calculated fields, and the calculated fields created after Data blending?

  A. No difference, calculated fields cannot be created in Blends

  B. Fields used in Blends must first be aggregated

  C. The calculated fields created in Blends cannot be edited once created

  D. The calculated fields created in Blends cannot use more than 2 fields

  Correct Answer: B

  Yes, due to the nature of blends, there are some conditions as follows from the official documentation that must be kept in mind while working with blends: In addition to handling calculations slightly differently, there are some limitations on secondary data sources. You may not be able to sort by a field from a secondary data source, and action filters may not work as expected with blended data. For more information, see Other data blending issues.

• Question 90:

  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

  Correct Answer: D

  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).
