What should you add?
A. A reference band
B. A reference line
C. An average line
D. A distribution band
Answer: A
Explanation:
A reference band is a shaded area that shows a range of values on an axis. You can use a reference
band to highlight a target range, a confidence interval, or a standard deviation. In this case, you want
to add a reference band that shows the range of values from 0 to 100 on the y-axis. This will create a
shaded area behind the bars that indicates the percentage of sales. To add a reference band, you
need to do the following steps:
Click on the Analytics tab on the left side of the workbook to open the Analytics pane. You will see a
list of analytical objects that you can drag and drop onto your worksheet.
Drag Reference Band from the Analytics pane to Y-Axis on the worksheet. This will add a reference
band on the y-axis that shows the average and confidence interval for all values.
Click on the Edit button on the reference band to open the Edit Reference Band dialog box. You will
see options to customize your reference band.
Change the Band From value to 0 and the Band To value to 100. This will change the reference band
to show the range of values from 0 to 100 on the y-axis.
Click OK to apply the changes. You will see that the reference band now shows a shaded area
behind the bars.

2.You create a parameter named Choose Region fiat contains values from a field named Region.
You want users to be able to use the Choose Region parameter to interact with a chart by logging
between different regions
What should you do next?
A. Add Region to me Fitters card
B. Add the [Region] = [choose Region) formula to the Filters card
C. Add the Choose Region parameter to the Pages card
D. Set the Choose Region parameter to Single Value (list)
Answer: B
Explanation:
To use the Choose Region parameter to interact with a chart by toggling between different regions,
you should add the [Region] = [Choose Region] formula to the Filters card. This formula will create a
boolean filter that returns TRUE if the value in the Region field matches the value in the Choose
Region parameter, and FALSE otherwise. You can add this formula to the Filters card by right-clicking
on it and selecting Add Filter from the menu. Then you can select Condition from the dialog box and
enter the formula in the text box. This will filter the chart to show only the data for the selected region.
The other options are not correct for this scenario. Adding Region to the Filters card will create a
categorical filter that shows a list of values from the Region field, but it will not use the Choose Region
parameter. Adding the Choose Region parameter to the Pages card will create a page control that
allows you to cycle through different values of the parameter, but it will not filter the chart. Setting the
Choose Region parameter to Single Value (list) will change how the parameter control appears on the
worksheet, but it will not affect how it interacts with the chart.

You want to show only visualization at time. Users must be able to switch between visualizations.
What should you me?
A. A parameter and a calculated filed
B. Worksheet actions
C. Showhide buttons
D. Dashboard 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
 5 / 10
https://www.dumpsinfo.com/
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.

5.You have the following dataset.
Which grouping option should you use m Tableau Prep to group al five names automatically?
A. Pronunciation
B. Spelling
C. Common Characters
D. Manual Selection
Answer: D
Explanation:
To group all five names automatically, you should use Manual Selection as a grouping option in
Tableau Prep. Manual Selection is a feature that allows you to select values from your data and group
them together based on your criteria. You can use Manual Selection by clicking on Group Values in
Profile pane > Manual Selection from the menu. This will open a dialog box where you can select
values from your data and assign them to a group.
In this case, you want to group all five names together based on their spelling variations. You can use
Manual Selection by selecting all five values from your data and assigning them to a group named
“Harry Potter”. This will create a new field named Grouped Field that contains “Harry Potter” as one
value.
The other options are not correct for this scenario. Pronunciation is a feature that groups values
based on how they sound, but it may not work well with names or uncommon words. Spelling is a
feature that groups values based on common spelling errors or typos, but it may not recognize all
variations or synonyms. Common Characters is a feature that groups values based on the number of
characters they share, but it may not capture the meaning or context of the values.

6.You have the following dashboard.
 6 / 10
https://www.dumpsinfo.com/
Currently the map is used as a filter that affects the data on the otter sheets of the dashboard
You need to configure the dashboard to ensure that selecting a data point on the map only tillers the
Detail table
What should you do?
A. From the context menu of Sales over time select Ignore Actions
B. From the context menu of Sales over lime select Remove Dashboard Item
C. From the context menu of Profits by Stale deselect Use as Filter
D. From the context menu of Sales over timeselect Deselect
Answer: A
Explanation:
To configure the dashboard to ensure that selecting a data point on the map only filters the Detail
table, you should select Ignore Actions from the context menu of Sales over time. Ignore Actions is a
feature that allows you to exclude a sheet from being affected by any actions on the dashboard, such
as filters or highlights. You can select Ignore Actions by right-clicking on a sheet on the dashboard
and selecting Ignore Actions from the menu.
In this case, you want to exclude Sales over time from being filtered by the map, so you should select
Ignore Actions from its context menu. This will make Sales over time ignore any selections on the
map and show all values. The Detail table will still be filtered by the map as usual.
The other options are not correct for this scenario. Removing Dashboard Item will delete Sales over
time from the dashboard, which is not what you want. Deselecting Use as Filter will disable the map
as a filter for any sheet on the dashboard, which is not what you want. Selecting Deselect will clear
any selections on the map, but it will not prevent Sales over time from being filtered by future
selections.

10.You want to add a comment to March 2020 as shown in the following visualization.
You have the following sets in a Tableau workbook
• Top N Customers
• Customers of 2020
• Top N Products
• Sellers of 2020
Which two sets can you combine? Choose two
A. Sellers of 2020
B. Customers of 2020
C. Top N Products
D. Top N Customers
Answer: BD
Explanation:
To combine two sets, they must have at least one dimension in common. In this case, Customers of
2020 and Top N Customers both have Customer Name as a dimension, so they can be combined
using set operations such as union, intersection, or difference. Sellers of 2020 and Top N Products
have different dimensions (Seller Name and Product Name), so they cannot be combined.
