質問 # 39
Open the link to Book1 found on the desktop. Open Disciplines worksheet.
Filter the table to show the members of the Top10 set and the members of the Bottom10 set. There should be a total of 20 rows.

正解：

解説：
check the steps below in explanation.
Explanation:
To filter the table to show the members of the Top10 set and the Bottom10 set, you need to do the following steps:
Open the link to Book1 found on the desktop. This will open the Tableau workbook that contains the Disciplines worksheet.
Click on the Disciplines tab at the bottom of the workbook to open the worksheet. You will see a table that shows the disciplines, sales, and profit for each salesperson.
Click on the drop-down arrow next to Salesperson on the Filters shelf. This will open a menu that allows you to filter by different criteria.
Select Set from the menu. This will show you the sets that are available for the Salesperson field. You will see Top10 and Bottom10 as two sets that have been created based on the sales ranking.
Check the boxes next to Top10 and Bottom10. This will filter the table to show only the members of these two sets. You can also click on All to deselect all other values.
Click OK to apply the filter. You will see that the table now shows 20 rows, 10 for each set.

質問 # 40
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 Choose Region parameter to the Pages card
• C. Add the [Region] = [choose Region) formula to the Filters card
• D. Set the Choose Region parameter to Single Value (list)

正解：A

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.

質問 # 42
Open the link to Book1 found on the desktop. Use the Superstore data source.
Split the Customer Name field into two fields named First Name and Last Name.

正解：

解説：
check the steps below in explanation.
Explanation:
To split the Customer Name field into two fields named First Name and Last Name, you need to do the following steps:
Open the link to Book1 found on the desktop. This will open the Tableau workbook that uses the Superstore data source.
Go to the Data Source tab at the bottom of the workbook to see the data source page. You will see a table that shows the fields and values from the Superstore data source.
Right-click on Customer Name in the table and select Split from the menu. This will split the field into two fields based on a separator, which is a space by default. You will see two new fields named Customer Name - Split 1 and Customer Name - Split 2 in the table.
Right-click on Customer Name - Split 1 and select Rename from the menu. Type First Name as the new name and press Enter. This will rename the field as First Name.
Right-click on Customer Name - Split 2 and select Rename from the menu. Type Last Name as the new name and press Enter. This will rename the field as Last Name.

質問 # 43
You have the following dataset.

Which Level of Detail (LOD) expression should you use to calculate tie grand total of all the regions?

• A. {FIXED: [Region] SUM Sales}
• B. {FIXED: TOTAL (Sales)}
• C. {Fixed: [Region]: TOTAL Sales}
• D. {FIXED: SUM Sales}

正解：B

解説：
To calculate the grand total of all the regions, you need to use a Level of Detail (LOD) expression that ignores any dimensions in the view and returns the total sum of sales. The FIXED keyword allows you to specify the level of detail for the calculation, and the TOTAL function returns the sum of all values in the expression. Therefore, the correct LOD expression is {FIXED: TOTAL (Sales)}. Reference: https://help.tableau.com/current/pro/desktop/en-us/calculations_calculatedfields_lod.htm https://help.tableau.com/current/pro/desktop/en-us/functions_functions_tablecalculation.htm#TOTAL

質問 # 44
You have the following visualization.

The Last() calculation is set to compute using Table (across)
Which value will appear in the crosstab for the Consumer segment of the year 2018 if you change compute to use Oder Dale?

• A. 0
• B. 1
• C. 2
• D. 3

正解：B

解説：
The value that will appear in the crosstab for the Consumer segment of the year 2018 if you change compute to use Order Date is 0. The Last() calculation is a table calculation that returns the number of rows from the current row to the last row in the partition. The partition is determined by how you compute the calculation. In this case, you change compute to use Order Date, which means that the calculation will be performed for each value of Order Date.
The crosstab shows that there are two values of Order Date for the Consumer segment of the year 2018: Q1 and Q4. The Last() calculation will return 0 for Q4, because it is the last row in the partition. It will return 1 for Q1, because it is one row away from the last row in the partition.
The other options are not correct for this scenario. The Last() calculation will not return 2, 3, or 4 for any value of Order Date, because there are only two values in each partition.

質問 # 45

• B. Create groups
• C. Rename the fields
• D. Create aliases

正解：D

解説：
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".

質問 # 51
You have the following visualization.

You Create a table calculation named Rank_Score that has a formula of RANK(AVG([Score]), and you drag Rank_Score to Text on the Marks cards.
What is the Rank Score value for Student ID 4220?

• A. 0
• B. 1
• C. 2
• D. 3

正解：B

解説：
the rank function returns the rank of each row within the partition of a result set. The rank of a row is one plus the number of ranks that come before the row in question.
To answer your question, we need to apply the rank function to the Avg Score column and sort it in descending order. Then we can find the rank score value for Student ID 4220 by looking at the corresponding row.
Here is how the table would look like after applying the rank function and sorting:

As you can see, the rank score value for Student ID 4220 is 1.

質問 # 52
You need to change the values of a dimension without creating a new field.
What should you do?

• A. Transforms the fields
• B. Create groups
• C. Rename the fields
• D. Create aliases

正解：D

解説：
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".
In Tableau, aliases can be used to change the way dimension members appear without altering the underlying data. This is useful for display purposes and does not create a new field within the dataset.

質問 # 53

Which function should you use to remove the semicolons from the Name field?

• A. SPLIT
• B. REPLACE
• C. TRIM
• D. CONTAINS

正解：B

解説：
The REPLACE function is used to replace all occurrences of a substring within a string with another substring.
In this case, it can be used to remove the semicolons from the Name field by replacing them with an empty string. For example, REPLACE ("John;Doe", ";", "") = "JohnDoe". References: The information is based on the following sources:
