You can create _______________ for members in a dimension so that their labels appear differently in the view.

• A.parameters
• B.duplicates
• C.copies
• D.aliases

Correct Answer: D

Explanation
You can create aliases (alternate names) for members in a dimension so that their labels appear differently in the view.
Aliases can be created for the members of discrete dimensions only. They cannot be created for continuous dimensions, dates, or measures.
To create an alias:

1) In the Data pane, right-click a dimension and select Aliases.
2) In the Edit Aliases dialog box, under Value (Alias), select a member and enter a new name.

* To submit your changes: In Tableau Desktop, click OK.
On Tableau Server or Tableau Online, click the X icon in the top-right corner of the dialog box.
When you add the field to the view, the alias names appear as labels in the view. For example:

What is the one critical difference between normal calculated fields, and the calculated fields created after Data blending?

• A.No difference, calculated fields cannot be created in Blends
• B.Fields used in Blends must first be aggregated
• C.The calculated fields created in Blends cannot be edited once created
• D.The calculated fields created in Blends cannot use more than 2 fields

Correct Answer: B

Explanation
Yes, due to the nature of blends, there are some conditions as follows from the official documentation that must be kept in mind while working with blends:


In addition to handling calculations slightly differently, there are some limitations on secondary data sources.
You may not be able to sort by a field from a secondary data source, and action filters may not work as expected with blended data. For more information, see Other data blending issues.

________________ can only create header. _______________ will create header and axis both.

• A.Dimensions, Measures
• B.Measures, Dimensions
• C.Groups, Sets
• D.Dates, Strings

Correct Answer: A

Explanation
Using the Sample superstore as a reference:
1) Let's plot a bar chart showing SUM(Quantity) for each Segment:
2) Right click on the x-axis (Segment):
Notice we don't have an option to edit the axis, only header. This is because only continous values form the AXIS.
3) Similarly, right click on the y-axis (Quantity):

Now we have the option to edit BOTH the axis and the header.

If you see the following Filter, then you're working with _______________________ Larger image

• A.Grouped Dates
• B.Date Functions
• C.Date Parts
• D.Date Values

Correct Answer: D

Explanation
Dates in Tableau will behave differently depending on whether they are a Datepart (blue) or a Datevalue (green). This affects how the axes display/behave and also how visualisations such as line charts will display.
The difference essentially boils down to Dateparts behaving like a dimension as opposed to a measure which is how Datevalues behave. This means that Dateparts behave like discrete categories on the view whereas Datevalues are more like continuous numeric values.
Dateparts are discrete and they behave the same as dimension filters. If all dates are used on the filter then each individual date will be a datepart that can be selected/excluded. This is the same for each level of date, if datepart months is placed on filters January to December will be tick-able options in the filter. This also means that conditions and top/bottom filters can be applied to datepart filters like any other dimension filter.
Datevalues placed on filters behave like measure filters. A min and a max date can be set and there is a relative dates option which allows you to choose things like only show the previous 3 months or years etc.
