Question#1

You want to add a draft watermark to a dashboard as shown in the following exhibit.



Which type of object should you use?

A. Image
B. Sheet
C. Web page
D. Horizontal

Explanation:
To add a draft watermark to a dashboard, you should use a sheet as a type of object. A sheet is a worksheet that contains a chart or a table that you can add to your dashboard. You can create a sheet that shows the word “Draft” as a text mark and format it with transparency, size, and color. Then you can drag the sheet to your dashboard and position it behind your other sheets as a floating element. You can also adjust the opacity and layering of the sheet to make it look like a watermark.

Question#2

You have the following dataset in Microsoft Excel.



You are using interpreter to cleans the dataset.
Data interpreter provides the following results.



How many rows of data will be ingested into Tableau as values?

A. 10
B. 20
C. 17
D. 15

Explanation:
Data interpreter is a feature that helps you clean and structure your data in Excel before importing it into Tableau. It detects and removes any headers, footers, subtotals, or other elements that are not part of the actual data. It also splits any merged cells and fills in any missing values.
In this case, data interpreter provides the following results:
It removes the first three rows and the last two rows that contain headers and footers.
It splits the merged cells in column A and fills in the missing values with “Fiction” or “Non-Fiction”.
It does not remove or change any other rows or cells.
Therefore, the number of rows of data that will be ingested into Tableau as values is 17, which is the number of rows left after removing the headers and footers.

Question#5

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 table calculation filter used on Sheet
B. A top N condition filer on a dimension in Sheet 1 and Sheet2
C. A context filler on a dimension m Sheet3
D. A dimension filter on all the sheets

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.
