NEW QUESTION # 70
You plan to create a visualization that has a dual axis chart. The dual axis chart will contain a shape chart and a line chart will use the same measure named Population on the axis.
You need to configure be shapes to be much larger than the line.
What should you do?
- A. For the second axis select Shape on the Marks card From Select Shape Palette select Custom and then select Reset
- B. Change Population to a discrete dimension
- C. Create a custom shape that is larger than the default shape and add the shape to the Shapes folder in My Repository
- D. Duplicate Population Drag the duplicate to the second Marks card and configure the see of the marks independently
Answer: D
Explanation:
To configure the shapes to be much larger than the line, you need to duplicate Population and drag it to the second Marks card. This will create a dual axis chart with two measures on one axis. You can then select Shape on one Marks card and Line on another Marks card, and adjust the size of each mark independently using the Size slider or menu.

In a dual-axis chart in Tableau, if you want to have two different visual mark types (like a shape and a line) and configure them differently (such as making one larger than the other), you would need to duplicate the measure. You then drag this duplicate to the second Marks card (which represents the second axis). There, you can adjust the size of the marks (shapes, in this case) independently of the line marks on the first Marks card.

NEW QUESTION # 73
You have a Tableau workbook that contain three worksheets named Sheet1 Sheet2 and Sheet3.
You create several filters.
From the Data Source page you plan to add data source fillers
When type of filter will appear in the Edit Data Source Filters dialog box?
- A. A dimension filter on all the sheets
- B. A table calculation filter used on Sheet
- C. A context filler on a dimension m Sheet3
- D. A top N condition filer on a dimension in Sheet 1 and Sheet2
Answer: A
Explanation:
A data source filter is a filter that applies to all the worksheets that use the same data source. It filters the data before any other filters or calculations are applied. You can add a data source filter from the Data Source page by clicking on the Add button next to Filters.
The type of filter that will appear in the Edit Data Source Filters dialog box is a dimension filter on all the sheets. This means that you can choose a dimension from your data source and filter it by values, range, condition, or top/bottom. The filter will affect all the worksheets that use that dimension.
The other types of filters are not data source filters and will not appear in the Edit Data Source Filters dialog box. A table calculation filter is a filter that applies to a table calculation, such as percent of total or running total. A top N condition filter is a filter that shows only the top or bottom N values of a measure or dimension based on a condition. A context filter is a filter that creates a subset of data that other filters can use.

https://help.tableau.com/current/pro/desktop/en-us/filtering_topn.htm
https://help.tableau.com/current/pro/desktop/en-us/filtering_context.htm Data source filters in Tableau apply to the entire data source, affecting all sheets that use that data source. The Edit Data Source Filters dialog box allows you to add filters that operate at the data source level, which is different from context filters, top N filters, or table calculation filters that are applied at the worksheet level.

NEW QUESTION # 75
You have the following dashboard that contains two visualizations.
You want to show only one visualization at time. Users must be able to switch between visualizations.
What should you me?
- A. Worksheet actions
- B. A parameter and a calculated filed
- C. Dashboard actions
- D. Show/hide buttons
Answer: B
Explanation:
In Tableau, you can manage the visibility of different visualizations on a dashboard using various techniques.
Among the options provided, the most straightforward method to allow users to switch between two visualizations is to use show/hide buttons.
Here's why each option is or isn't suitable for the requirement:
A). A parameter and a calculated field: While it's possible to use a parameter and a calculated field to control which visualization is displayed, it requires creating a calculated field that responds to a parameter and then using that field to filter the view. This method can become complex and is not as user-friendly for simply showing and hiding visualizations.
B). Worksheet actions: Worksheet actions in Tableau typically allow users to interact with the data within a visualization, such as filtering data or highlighting related data points when clicking or hovering. They are not designed to control the visibility of entire visualizations on a dashboard.
C). Show/hide buttons: Show/hide buttons are a feature specifically designed to manage the visibility of dashboard elements. When you create a show/hide button, it can be configured to display or hide a particular visualization, container, or any other dashboard element when clicked. This provides a very intuitive interface for users to switch between visualizations.
D). Dashboard actions: Dashboard actions, like worksheet actions, are used to create interactions between sheets, such as filtering data or navigating to other sheets or URLs based on user interactions. They are not intended for toggling the visibility of visualizations.
Therefore, the correct answer is C. Show/hide buttons as they provide a user-friendly way to switch between visualizations on a dashboard without the need for complex calculations or actions that aren't meant for this purpose. The show/hide button feature is specifically designed for toggling visibility and offers a simple and effective solution for the requirement.
NEW QUESTION # 76
You have a dashboard that contains confidential information about patients health. The data needs to always be up to date tor a team of healthcare workers How should you share me dashboard with the healthcare workers?
- A. Print the dashboard to PDF
- B. Export the dashboard as a .twbx
- C. Publish the dashboard to Tableau Public
- D. Publish the dashboard to Tableau Server
Answer: D
Explanation:
To share a dashboard that contains confidential information about patients health and needs to always be up to date for a team of healthcare workers, you should publish it to Tableau Server. This will allow you to control who can access and interact with your dashboard, as well as schedule automatic refreshes of your data source or extract. Publishing to Tableau Public would expose your data to anyone on the internet, printing to PDF would not update your data, and exporting as a .twbx would require sending a large file that might not be compatible with other versions of Tableau. References:
https://help.tableau.com/current/pro/desktop/en-us/publish_workbooks_share.htm
https://help.tableau.com/current/pro/desktop/en-us/publish_workbooks_tableauserver.htm When sharing sensitive and confidential information that needs to be kept up-to-date, such as patient health data for a team of healthcare workers, the best practice is to publish the dashboard to Tableau Server. Tableau Server is designed for secure, controlled access and can be configured to ensure that data is refreshed as needed. Publishing to Tableau Public is not secure for confidential data, printing to PDF or exporting as a
.twbx does not allow for live data updates.
NEW QUESTION # 77
You are creating a new dashboard.
You need to add a button to the dashboard that allows users to export the dashboard as an image.
Which type of object should you use?
- A. Download
- B. Extension
- C. Ask Data
- D. Image
- E. Navigation
Answer: B
Explanation:
Extensions in Tableau are web-based programs that can interact with dashboards. To add a button that allows users to export the dashboard as an image, you would use an Extension object. This could be a custom extension designed to trigger the download of the dashboard view as an image.
NEW QUESTION # 78
You have the following chart that shows profits and discounts over time.
You need to combine the lines to appear as shown in the following chart.
What should you do?
- A. Set Discount to Dual Axis
- B. Convert Discount to Discrete
- C. Drag Discount to the Columns shelf
- D. Drag Discount to Color on the Marks card
Answer: A
Explanation:
To combine the lines to appear as shown in the second chart, you should set Discount to Dual Axis. Dual Axis is a feature that allows you to show two measures on two separate axes on one chart. You can create a dual axis by right-clicking on a measure on any shelf and selecting Dual Axis from the menu. This will create two axes on one chart and synchronize their scales.
In this case, you want to show Profit and Discount on two separate axes on one chart. You can right-click on Discount on any shelf and select Dual Axis from the menu. This will create a dual axis chart that shows Profit and Discount as two lines with different colors.
The other options are not correct for this scenario. Dragging Discount to Color on the Marks card will change the color of Profit based on Discount, but it will not show two lines. Converting Discount to Discrete will change Discount from a green pill to a blue pill, but it will not affect how it appears on the chart. Dragging Discount to Columns shelf will create two separate charts for Profit and Discount, but it will not combine them.
