NEW QUESTION # 31
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 top N condition filer on a dimension in Sheet 1 and Sheet2
- B. A table calculation filter used on Sheet
- C. A dimension filter on all the sheets
- D. A context filler on a dimension m Sheet3
Answer: C
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_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 # 32
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.)
Answer:
Explanation:
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.

NEW QUESTION # 33
You have the following chart that sorts states by the number of products each state has purchased.
Which formula should you use to include a number with the position of each state within each region?
- A. WINDOW_SUM(SUM ([Quantity]))
- B. FIRST ()
- C. LOOKUP (SUM ([Quantity]))
- D. INDEX ()
Answer: C
Explanation:
The LOOKUP function is used to return the value of a specified field in a different row, which can be defined relative to the current row. In this context, it can be used to include a number with the position of each state within each region by looking up the SUM([Quantity]) in each respective position.

NEW QUESTION # 35
You have the following table.
You need each record to alternate between grey and white.
What should you change in the Format Shading pane?
- A. the column banding size to 1
- B. the column banding size to 3
- C. the row banding size to 3
- D. the row banding size to 1
Answer: D
Explanation:
To have each record alternate between grey and white, you should change the row banding size to 1 in the Format Shading pane. This setting will ensure that each row has a different shading from the one above and below it, creating an alternating pattern of grey and white rows. References: The answer can be verified through practical application within Tableau or by consulting Tableau's official learning resources, such as Tableau Help: Format Shading or Tableau Training Pass: Formatting.
NEW QUESTION # 36
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) ) / (LOOKUP (SUM ([Sales]), -4) )
- B. (SUM ([Sales]) - LOOKUP (SUM ( [Sales]), -4))
- C. (ZN (SUM ([Sales]) ) - LOOKUP (ZN (SUM ([Sales]) ), -4) )
- D. (SUM([Sales]) / (LOOKUP (SUM ([Sales]), -4))
Answer: A
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:

- C. Date
- D. Integer
- E. Boolean
- F. Datetime
Answer: B,D
Explanation:
In the context of filtering data in Tableau, both string and integer parameters can be used to dynamically filter data. A string parameter can be used to filter text-based values, while an integer parameter is suitable for numerical values. In the provided dataset and result URLs, it appears that a unique identifier or key (which could be a string or integer) is being used to filter specific data entries.

NEW QUESTION # 41
You publish a dashboard that uses an extract. The extract refreshes every Monday at 10:00.
You need to ensure that the extract also refreshes on the last day of the month at 18:00.
What should you do?
- A. From Tableau Server, select Schedules, find the schedule of the extract, and change the frequency to the last day of the month.
- B. From Tableau Server, select Schedules, and change the priority of the existing schedule.
- C. From Tableau Server, select the workbook, select Refresh Extracts, and then add a new extract refresh.
- D. From Tableau Desktop, open the Publish Workbook dialog box and configure the schedule.
Answer: C
Explanation:
To ensure that the extract also refreshes on the last day of the month at 18:00, you need to add a new extract refresh task to the workbook on Tableau Server. You can do this by selecting the workbook, selecting Refresh Extracts, and then choosing Schedule a Refresh. You can then select an existing schedule that matches your desired frequency and time, or create a new schedule with a custom frequency and time. This will add a new extract refresh task to the workbook, in addition to the existing one that refreshes every Monday at 10:00. You can also modify or delete the extract refresh tasks as needed.

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. For the data type of the Material field, select Custom, and then select Role1.
- B. From the More actions menu of Materials, filter the selected values.
- C. From the More actions menu of Materials, select Group Values, and then select Spelling.
- D. From the More actions menu of Materials, select Valid in the Show values section.
Answer: A,C
Explanation:
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:
