*Very important question*

If we select the labels in the view and then group, a new consolidated mark is created -in our case bar since we are talking about a bar chart in the question. See below:

Then on grouping, a new bar is created, and the colour of all bars remain the same.

Had we grouped by choosing the marks instead of the labels, the following would be the result:

Correct Answer: C

Presently, there is no official way to connect your data in Firebase directly with Tableau Desktop.

A workaround however can be to export your Firebase data into Google BigQuery, and then connect it to Tableau Desktop.

But then again, it is a workaround and not an official out-of-the-box solution.

The following are the available Data sources available as of now:

1) Server

2) File

Correct Answer: ADE

According to the official documentation:

Joins are a more static way to combine data. Joins must be defined between physical tables up front, before analysis, and can't be changed without impacting all sheets using that data source. Joined tables are always merged into a single table. As a result, sometimes joined data is missing unmatched values, or duplicates aggregated values.

Joins1) Are displayed with Venn diagram icons between physical tables 2) Require you to select join types and join clauses 3) Joined physical tables are merged into a single logical table with a fixed combination of data 4) May drop unmatched measure values 5) May duplicate aggregate values when fields are at different levels of detail 6) Support scenarios that require a single table of data, such as extract filters and aggregation

Correct Answer: B

It is possible in Tableau to use a sheet within a story directly. Moreover, in Tableau, a story is a sequence of visualizations that work together to convey information. You can create stories to tell a data narrative, provide context, demonstrate how decisions relate to outcomes, or to simply make a compelling case. At the same time, a story is also a collection of sheets, arranged in a sequence. Each individual sheet in a story is called a story point.

Correct Answer: B

We know that continuous fields will always create an axis, so options stating 'header' are automatically eliminated. For our question, see below: Teams Had the question asked us to place this pill on the Rows shelf instead, we would've gotten a different answer:

Correct Answer: A

To reach the correct answer, follow the steps below:

1) Drag Category, and sub-category to the row shelf. Drag Profit to the Column shelf

2) Click the Sort-ascending icon as shown above, to sort the profits from least to greatest as shown:

Click the 'Show mark labels icon'

As we can see, Fasteners has the least Profit in the Office Supplies Category, and hence is our correct answer!

Correct Answer: D

Your Tableau Desktop Specialist exam will be based on the 2020.1 version. Set controls are a new feature introduced in the 2020.2 version, and hence is the correct answer-it is not a part of 2020.1

For the 2020.1 version the new features were:

1) Viz animations:

Viz animations help you see and understand your changing data. It's easy to track the logical steps behind data's evolution and tell powerful data stories. Sorting, filtering, adding fields, and other actions will now smoothly animate your

visualizations. Choose whether to turn Viz Animations on or off, and decide how you'd best like to apply animations to your new workbooks.

2) Dynamic Parameters:

Say goodbye to republishing workbooks with parameters every time the underlying data changes. Set your parameter once, and Tableau will automatically update the parameter's list of values every time someone opens the workbook.

3) Buffer Calculations:

Buffer calculations allow you to visualize the distance around point locations. Give Tableau three parameters--location, distance, and a unit of measure--and a buffer, or boundary is instantly created. Answering complex spatial questions becomes easier than ever before--visualize what properties are within 200 meters of a proposed transit site, or how many competitors' stores are within 1 mile of their store, and more.
