Question: 92


Dates in Tableau are typically treated as

  1. Dimensions

  2. Measures


Answer: A Explanation:

For relational data sources, dates and times are automatically placed in the Dimensions area of the Data pane and are identified by the date or date-time icon. For example, the Order Date and Ship Date dimensions from an Excel data source are shown below:



When you place a relational date on a shelf, the field name is automatically modified to reflect the default date level. Tableau defines the default date level to be the level at which there are multiple instances. For example, if the date field includes multiple years, the default level is year. However, if the date field contains data for just one year but includes multiple months, then the default level is month.

Question: 93


True or False: It is possible to change the Geographic Role of a dimension

  1. True

  2. False


Answer: A Explanation:

Explanation A geographic role associates each value in a field with a latitude and longitude value. Assigning a geographic role based on the type of location (such as state versus postcode) helps ensure that your data is plotted correctly on your map view. For example, you can assign the City geographic role to a field that contains a list of city names. To assign a geographic role to a field: In the Data pane, click the data type icon next to the field, select Geographic Role, and then select the geographic role you want to assign to the field.


When you assign a geographic role to a field, Tableau adds two fields to the Measures area of the Data pane: Latitude (generated) and Longitude (generated). These fields contain latitude and longitude values and are assigned the Latitude and Longitude geographic roles. If you double-click each of these fields, Tableau adds them to the Columns and Rows shelves and creates a map view using the Tableau background map.

Which of the following are the options to export the data used to build the view / visualisations?

  1. CSV file

  2. PDF File

  3. JSON format

  4. MS Access Database


Answer: D Explanation:

You can export the data in a Tableau data source, including all or part of the records from


your original data. Alternatively, you can export only the portion of data used to generate the view. Since the question mentions the data used to build the view, we’ll focus on that :


*Export data in the view to Microsoft Access or .csv* Export the data that is used to generate the view as an Access database (Windows only) or .csv file (Mac only).


  1. In Tableau Desktop, select Worksheet > Export > Data.


  2. Select a location and type a name for your Access database or .csv file.


  3. Click Save.


  4. If you’re on Windows, the Export Data to Access dialog box displays to give you the option to immediately use the new Access database and continue working in Access without interrupting your work flow.

Question: 99


Which of the following are benefits of using Data Extracts in Tableau?

  1. Improved Performance

  2. Ability to use the data offline

  3. Working with freshest data at all times

  4. Faster to work with


Answer: A,B,D Explanation:

Explanation Extracts are advantageous for several reasons:


  1. Supports large data sets: You can create extracts that contain billions of rows of data.


  2. Fast to create: If you’re working with large data sets, creating and working with extracts can be faster than working with the original data.


  3. Help improve performance: When you interact with views that use extract data sources, you generally experience better performance than when interacting with views based on connections to the original data.

  4. Support additional functionality: Extracts allow you to take advantage of Tableau functionality that’s not available or supported by the original data, such as the ability to compute Count Distinct.


  5. Provide offline access to your data: Extracts allow you to save and work with the data locally when the original data is not available. For example, when you are traveling.


To work with the MOST up-do-date data, use a live connection instead! Reference: https://help.tableau.com/current/pro/desktop/en-us/extracting_data.htm Question: 100
