NEW QUESTION # 17
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. Export the dashboard as a .twbx
- B. Print the dashboard to PDF
- 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_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 # 18
You have the following dashboard that contains two visualizations.
You want to show only visualization at time. Users must be able to switch between visualizations.
What should you me?
- A. Dashboard actions
- B. Showhide buttons
- C. A parameter and a calculated filed
- D. Worksheet actions
Answer: C
Explanation:
Showhide buttons are a feature that allows you to show or hide a layout container on a dashboard. You can use showhide buttons to create a toggle effect that switches between two visualizations. You need to place each visualization in a separate layout container and then add a showhide button for each container. You can customize the appearance and behavior of the buttons to suit your needs.

NEW QUESTION # 23
You are developing a data source in Tableau Prep.
You have two tables named Orders and Employees.
The Orders table was created in 2019 and contains the following columns.
The Employees table contains all the employee information for the various sales teams in the sales department and contains the following columns You want to prepare the data so that you can analyze sales trends over time for every sales team.
Which three actions should you perform in order? (Place the three correct options in order. Use the arrows to move Options to Answer Area. Use Answer Area arrows to re-order the options.)
Answer:
Explanation:
There are different ways to prepare the data in Tableau Prep, but one possible answer is:
Answer area:
* Join the tables.
* Aggregate the data by Sales Team.
* Add the following filter to the Employees table: Sale Team - Team Alpha.
To analyze sales trends over time for every sales team, you need to combine the data from the Orders and Employees tables. You can do this by joining the tables on the Rep ID column, which is a common identifier for both tables. This will create a single table with all the columns from both tables. Next, you need to aggregate the data by Sales Team, which is the level of analysis you want. You can do this by grouping the data by the Sales Team column and applying an aggregation function (such as sum, average, count, etc.) to the other columns that you want to measure (such as Total Amount, Rep Tenure, etc.). This will create a summary table with one row for each sales team and the aggregated values for the other columns. Finally, you need to filter the data to focus on a specific sales team, such as Team Alpha. You can do this by adding a filter to the Employees table and selecting only the rows where Sales Team equals Team Alpha. This will remove the rows for other sales teams and keep only the data for Team Alpha.

You connect to a database server by using Tableau Prep. The database server has a data role named Role1.
You have the following field in the data.
You need to apply the Role1 data role to the Material field.
Which two actions should you perform? Choose two.
- A. From the More actions menu of Materials, select Group Values, and then select Spelling.
- B. For the data type of the Material field, select Custom, and then select Role1.
- C. From the More actions menu of Materials, select Valid in the Show values section.
- D. From the More actions menu of Materials, filter the selected values.
Answer: A,B

NEW QUESTION # 27
You have the following dashboard that contains two sheets.
You want to minimize the whitespace between the sheets.
What should you configure?
- A. The position
- B. The padding
- C. The background
- D. The border
- E. The size
Answer: B
Explanation:
To minimize the whitespace between the sheets, you should configure the padding of the sheets and the dashboard. Padding is the amount of space between the edge of a sheet or dashboard and its content. You can adjust the padding by using the Layout tab in the Format pane. You can reduce the padding for each sheet by selecting the sheet and changing the values for the inner and outer padding. You can also reduce the padding for the dashboard by selecting the dashboard and changing the values for the outer padding. Reducing the padding will make the sheets and the dashboard more compact and eliminate unnecessary whitespace. Reference:

NEW QUESTION # 28
You have a data source that contains the following columns.
You want to filter regions based on the highest sales. Users must be able to specify the number of regions shown.
Which three actions should you perform in order? (Place the three correct options in order. Use the arrows to move Options to Answer Area.
Use Answer Area arrows to re-order the options.)
Answer:
Explanation:
To filter regions based on the highest sales and allow users to specify the number of regions shown, you should perform these actions in order:
Answer area:
* Create an integer data type parameter named Param1.
* Drag Region to the Filters shelf.
* Configure a Top filter by field. Use Param1 and filter by the sum of Sales.
To create a dynamic filter that lets users choose the number of regions to display, you need to use a parameter and a top filter. A parameter is a user-defined variable that can be used in calculations, filters, and reference lines. A top filter is a type of filter that shows only the top or bottom N values based on a specified field or expression.
In this question, you want to filter regions based on the highest sales. You also want users to be able to specify the number of regions shown. To achieve this, you need to follow these steps:
* First, you need to create an integer data type parameter named Param1. This parameter will allow users to enter a number that will determine how many regions to show. You can create a parameter by right- clicking on the Data pane and selecting Create Parameter. Then, you need to specify the name, data type, current value, and allowable values for the parameter. In this case, you can choose Integer as the data type, 10 as the current value, and All as the allowable values. You also need to show the parameter control by right-clicking on the parameter and selecting Show Parameter Control. This will display a slider or a text box where users can enter or adjust the parameter value.
* Next, you need to drag Region to the Filters shelf. This will open the Filter dialog box, where you can choose how to filter the Region field. You can filter by general, wildcard, condition, or top. In this case, you want to filter by top, so you need to select the Top tab.
* Finally, you need to configure a top filter by field. Use Param1 and filter by the sum of Sales. This will filter the Region field by showing only the top N regions based on the sum of Sales, where N is the value of the parameter Param1. You can configure a top filter by field by selecting By field in the Top tab, then choosing the parameter Param1 from the drop-down list, and selecting the aggregation function Sum and the field Sales from the other drop-down lists. This will create a filter expression that looks like this: Top Param1 by SUM(Sales).
By following these steps, you will create a filter that shows only the regions with the highest sales, and allows users to change the number of regions shown by adjusting the parameter value.

NEW QUESTION # 29
You need to change the values of a dimension without creating a new field.
What should you do?
- A. Create aliases
- B. Create groups
- C. Rename the fields
- D. Transforms the fields
Answer: A
Explanation:
You can create aliases for the members of a dimension by right-clicking the dimension in the Data pane or in the view and selecting Aliases. This changes how the values are displayed in the view, but not the underlying data. For example, you can create an alias for "Central" as "Midwest".

NEW QUESTION # 38
You have the following map.
You need the map to appear as shown in the following visualization.
What should you do?
- A. Change the mark type to Map
- B. Drag Location to Size on the Marks card
- C. Change the opacity to 75%
- D. Drag Population to Size on the Marks card
- E. Change the mark type to Density
Answer: E
Explanation:
The question presents a scenario where a geographic map visualization in Tableau needs to be transformed from a series of discrete circles representing data points to a density map visualization. The density map shows concentrations of data points with a gradient of color, where denser areas are indicated by a darker color.
Here's the explanation for each option:
A). Change the mark type to Density: This is the correct answer because changing the mark type to 'Density' in Tableau creates a density map, which displays the concentration of data points with a color gradient. This is exactly what is needed to achieve the visual effect shown in the second image, where regions with a higher concentration of data points are represented by darker shades.
B). Drag Location to Size on the Marks card: This option would adjust the size of the marks based on the number of locations, which is not relevant to creating a density map. It would result in varying sizes of circles, not a continuous gradient.
C). Change the mark type to Map: The visualization is already using a map. This option would not change the visualization to the desired density map.
D). Drag Population to Size on the Marks card: This would change the size of the circles based on the population values, making some circles larger and others smaller. This is not how a density map is created, which uses color intensity rather than size to show concentration.
E). Change the opacity to 75%: Changing the opacity would affect the transparency of the marks on the map but would not transform the visualization into a density map.
To achieve the visualization shown in the second image, the mark type must be changed to 'Density,' which will produce a heat map-like effect where the color intensity represents the concentration of data points.
Therefore, the correct answer is A. Change the mark type to Density.
To create a density map from a scatter plot of data points, you would change the mark type to Density. This mark type allows you to visualize the concentration of data points in an area, which can be useful for identifying clusters or patterns in geospatial data.

NEW QUESTION # 40
You have the following dataset.
Which formula calculates the percent difference in sales relative to the same quarter the previous year as shown in the Calculation field?
- A. (SUM([Sales]) / (LOOKUP (SUM ([Sales]), -4))
- B. (SUM ([Sales]) - LOOKUP (SUM ( [Sales]), -4))
- C. (SUM ([Sales]) - LOOKUP (SUM ([Sales]), -4) ) / (LOOKUP (SUM ([Sales]), -4) )
- D. (ZN (SUM ([Sales]) ) - LOOKUP (ZN (SUM ([Sales]) ), -4) )
Answer: C
Explanation:
The formula in option B calculates the percent difference in sales relative to the same quarter the previous year. It subtracts the sales of the same quarter from the previous year from the current year's sales, and then divides this by the previous year's sales. This gives a percentage change, which aligns with what is shown in the Calculation field of your dataset. The LOOKUP function returns the value of a specified offset from the current row in the partition. In this case, the offset is -4, which means the value of the same measure four rows above the current row. This corresponds to the same quarter of the previous year, assuming the data is sorted by quarter. References:
