質問 # 58
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 the Choose Region parameter to the Pages card
- B. Add Region to me Fitters card
- C. Add the [Region] = [choose Region) formula to the Filters card
- D. Set the Choose Region parameter to Single Value (list)
正解：C
解説：
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 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.

- C. From the More actions menu of Materials, select Group Values, and then select Spelling.
- D. From the More actions menu of Materials, filter the selected values.
正解：B、C
解説：
To apply a custom data role to a field, you need to select the data type of the field and then choose the data role from the list of available roles. This will validate the values in the field against the data role and mark any invalid values with a red exclamation mark. To fix the invalid values, you can use the Group Values option and select the Spelling algorithm, which will group values that are close in spelling and replace them with the most frequent value in the group. This will help you standardize the values in the Material field and match them with the Role1 data role. References: The information is based on the following sources:

質問 # 72
You have a table that contains four columns named Order Date, Country, Sales, and Profit.
You need to add a column that shows the day of the week for each row. For example, orders placed on August
31, 2022, will show a day of
Wednesday.
How should you complete the formula? (Use the dropdowns in the Answer Area to select the correct options to complete the formula.)
正解：
解説：
Explanation:
To add a column that shows the day of the week for each row, you should complete the formula as follows:
DATENAME
(
'weekday'
, [Order Date])
The DATENAME function in Tableau returns the name of a specified part of a date or datetime value, such as the year, month, or day. It takes two arguments: the date part and the date. In this question, you want to return the name of the weekday, such as Monday, Tuesday, or Wednesday, for each order date. Therefore, you need to use 'weekday' as the date part and [Order Date] as the date. The formula will return a string value that represents the name of the weekday for each order date.

質問 # 79
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. Convert Discount to Discrete
- B. Set Discount to Dual Axis
- C. Drag Discount to Color on the Marks card
- D. Drag Discount to the Columns shelf
正解：B
解説：
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.
