NEW QUESTION # 51
_____________ is a snapshot of the data that Tableau stores locally. Good for very large datasets of which we only need few fields.

• A. Tableau Workbook (.twb)
• B. Tableau Data Extract (.tde)
• C. Tableau Packaged Workbook (.twbx)
• D. Tableau Data Source (.tds)

Answer: B

Explanation:
Explanation
Tableau Data Extract (TDE) is a snapshot of the data that Tableau stores locally. Good for very large datasets of which we only need few fields. Performance is optimised because it queries its own database engine instead of the local data source.
When you create an extract of your data, you can reduce the total amount of data by using filters and configuring other limits. After you create an extract, you can refresh it with data from the original data. When refreshing the data, you have the option to either do a full refresh, which replaces all of the contents in the extract, or you can do an incremental refresh, which only adds rows that are new since the previous refresh.
Extracts are advantageous for several reasons:
1) Supports large data sets: You can create extracts that contain billions of rows of data.
2) Fast to create: If you're working with large data sets, creating and working with extracts can be faster than working with the original data.
3) Help improve performance: When you interact with views that use extract data sources, you generally experience better performance than when interacting with views based on connections to the original data.
4) Support additional functionality: Extracts allow you to take advantage of Tableau functionality that's not available or supported by the original data, such as the ability to compute Count Distinct.
5) Provide offline access to your data: Extracts allow you to save and work with the data locally when the original data is not available. For example, when you are traveling.

NEW QUESTION # 53
Suppose you have a bar chart. When we group by labels in a view, which of the following happens?

• A. Nothing changes in the view, but a group is created in the Dimensions shelf.
• B. A new mark (bar) is created, which consolidates all members of the group.
• C. Trick question! It is not possible to group by labels.
• D. The colours of the members selected are now the same, and different for the rest of the members.

Answer: B

Explanation:
Explanation
*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:

NEW QUESTION # 54
What term is used to describe the following picture?

• A. Set
• B. Parameter
• C. Hierarchy
• D. Group
• E. Larger image

Answer: A

Explanation:
Explanation
When you connect to a data source, Tableau automatically separates date fields into hierarchies so you can easily break down the viz. You can also create your own custom hierarchies. For example, if you have a set of fields named Region, State, and County, you can create a hierarchy from these fields so that you can quickly drill down between levels in the viz.

NEW QUESTION # 57
Which of the following is a valid way to create Sets in Tableau?

• A. In the Tableau Main Menu, choose Dashboard and select Create > Set
• B. In the Tableau Main Menu, Choose Worksheet and select Create > Set
• C. In the Data pane, right-click a measure and select Create > Set.
• D. In the Data pane, right-click a dimension and select Create > Set.

Answer: D

Explanation:
Explanation
There are two types of sets: dynamic sets and fixed sets. The members of a dynamic set change when the underlying data changes. Dynamic sets can only be based on a single dimension.
To create a dynamic set:
1) In the Data pane, right-click a dimension and select Create > Set.
2) In the Create Set dialog box, configure your set. You can configure your set using the following tabs:
General: Use the General tab to select one or more values that will be considered when computing the set.
You can alternatively select the Use all option to always consider all members even when new members are added or removed.

None of the other options exist, and therefore are incorrect answers.

NEW QUESTION # 58
What is the one most important thing you should do after creating a Dual-axis chart?

• A. Edit the labels
• B. Hide the axis
• C. Synchronise the axis
• D. Change the colours

Answer: C

Explanation:
Explanation
After creating a dual axis chart, make sure to synchronise their axis since they both might not be having the same y-axis.

To align the two axes in a dual axes chart to use the same scale, right-click (control-click on Mac) the secondary axis, and select Synchronize Axis. This aligns the scale of the secondary axis to the scale of the primary axis.
In this example, the Sales axis is the secondary axis and the Profit axis is the primary axis.
If you would like to change which axis is the primary, and which axis is the secondary, select the field on the Columns or Rows shelf that is the secondary, and drag it in front of the primary field on the shelf until you see an orange triangle appear.
In this example, you can select the SUM(Sales) field on the Rows shelf, and drag it in front of the SUM(Profit) field. The Sales axis is now the primary and the Profit axis is the secondary.

NEW QUESTION # 59
Which of the following would you use to edit the Shape, colour, and Text of your visualisations?

• A. Analytics Pane
• B. Marks Card
• C. Data Pane
• D. Filter Shelf

Answer: B

Explanation:
Explanation
The Marks Card allows us not only to edit the Shape, Text and Colour, but also to modify the Tooltip and the level of detail of the visualisation!

The Marks card is a key element for visual analysis in Tableau. As you drag fields to different properties in the Marks card, you add context and detail to the marks in the view.

You use the Marks card to set the mark type (see Change the Type of Mark in the View), and to encode your data with color, size, shape, text, and detail. To change the mark settings, see Control the Appearance of Marks in the View.

In this example, three different fields have been dragged to different properties in the Marks card. Segment is on Color, Region is on Shape, and Quantity is on Size.
After you add a field to the Marks card, you can click the icon next to the field to change the property it is using. You can also click the property buttons in the Marks card to change those settings.
Many properties can have multiple fields. For example, you can add multiple fields to Label, Detail, Tooltip, and Color. Size and Shape can only have one field at a time. For more details, see Control the Appearance of Marks in the View.

NEW QUESTION # 62
You can use the __________________ in Tableau to clean / organise your data.

• A. Data cleaner
• B. Data organiser
• C. Data manager
• D. Data interpreter

Answer: D

Explanation:
Explanation
When you track data in Excel spreadsheets, you create them with the human interface in mind. To make your spreadsheets easy to read, you might include things like titles, stacked headers, notes, maybe empty rows and columns to add white space, and you probably have multiple tabs of data too.
When you want to analyze this data in Tableau, these aesthetically pleasing attributes make it very difficult for Tableau to interpret your data. That's where Data Interpreter can help.

Using the Time Series table, create a chart that shows the percent difference in Average Inventory on Hand for each Assortment by year and quarter.
How many quarters did the Electronics Assortment show a negative percent difference in the Average Inventory On Hand?

• A. 0
• B. 1
• C. 2
• D. 3

Answer: A

Explanation:
Explanation
If you chose 2, then you were very close but probably didn't plot the actual Percent Difference on your view. ( One of the marks is just over the line).
* Firstly, Drop the Week ID onto the column shelf, and convert it to continuous since we need both Year and Quarter as mentioned in the question.
* 2) Next, Drop assortment to filters shelf so that we can focus on Electronics!

3) This should be your view now. Click on the Show Mark Labels icon as shown:
The final view is as follows, with 3 points below 0 ( i.e negative )
