Q95. Which of the following calculations DO NOT need a quick table calculation?

 Variance

 Rank

 Moving Average

 Standard Deviation

For Standard Deviation and Variance, we don’t need to use quick table calculations, since they are available by default. See below:

However, as seen in the types of quick table calculations available in Tableau, Rank and Moving Average belong to only this category.

Q96. A field that shows average home values for the United States in 2016 is most likely :

 A discrete date part dimension

 A continuous date value dimension

 A geographical dimension

 An aggregated measure

Explanation
This question is directly from the Official Tableau Desktop Specialist exam guide.
Since we are talking about the AVERAGE home values for the United States in 2016, the question is directly offering us a hint that the answer has something to do with aggregation and that too the values tell us that we’re working with MEASURES.
Date part and Date values don’t really make much sense given the question, and neither does geography.
Therefore, the answer naturally is “An aggregated measure”.

Q97. Broadly speaking, when users connect to Tableau, the data fields in their data set are automatically assigned a
____________ and a ____________.

 role, type

 Data type, Value

 type, role

 dimension, measure

Explanation
When users connect to Tableau, the data fields in their data set are automatically assigned a role and a type.
Role can be of the following two types:
1) Dimension
2) Measure
Type can be of the following :
1) String
2) Number
3) Geographic
4) Boolean
5) Date
6) Date and Time

Q98. True or False: It is not possible to blend axes for multiple measures into a single axis

 False

 True

We can very much blend multiple measures into a single axis. Such charts are called Combined-Axis / Blended-Axis charts. Follow along:
Measures can share a single axis so that all the marks are shown in a single pane. To blend multiple measures, drag one measure or axis and drop it onto an existing axis.

Instead of adding rows and columns to the view, when you blend measures there is a single row or column and all of the values for each measure is shown along one continuous axis. For example, the view below shows quarterly sales and profit on a shared axis.

Note: If you drag a measure on to the canvas and only see a single ruler indicator instead of the double ruler indicator shown below, Tableau creates dual axes instead of a blended axis. For more information about how to create dual axes, see Compare two measures using dual axes.

Q99. A Tableau Support case can be opened in which of the following valid ways?

 Using the Developer Community Forum

 Contacting Salesforce using their website

 Using the support option on the Tableau website

 Using the Tableau learn website

Explanation
It is possible to open a Tableau support case by visiting the following link :
https://www.tableau.com/support/case

Q100. You can create _______________ for members in a dimension so that their labels appear differently in the view.

 parameters

 duplicates

 copies

 aliases

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:

Q101. True or False: It is possible to change the Geographic Role of a dimension

 True

 False

Explanation
A geographic role associates each value in a field with a latitude and longitude value.
Assigning a geographic role based on the type of location (such as state versus postcode) helps ensure that your data is plotted correctly on your map view. For example, you can assign the City geographic role to a field that contains a list of city names.
To assign a geographic role to a field:
In the Data pane, click the data type icon next to the field, select Geographic Role, and then select the geographic role you want to assign to the field.

When you assign a geographic role to a field, Tableau adds two fields to the Measures area of the Data pane:
Latitude (generated) and Longitude (generated).
These fields contain latitude and longitude values and are assigned the Latitude and Longitude geographic roles. If you double-click each of these fields, Tableau adds them to the Columns and Rows shelves and creates a map view using the Tableau background map.

Q102. DOWNLOAD THE DATASET FROM:
https://drive.google.com/drive/folders/1WXzqsrNmXVdmQ-574wld4InEplyKT8RP?usp=sharing (if you haven’t already) Using the cwurData table, plot a Map to see which country had the Second highest number of patents in the Year 2013?

 United States

 France

 United Kingdom

 Canada

Explanation
Follow along to get the correct answer:
* Drag Country to the view, and then Patents to the Size Mark on the Marks shelf as follows :
2) But, this isn’t all right? We need to focus on the year 2013. This can be done by using the year column as it is (continuous) in the filter shelf, or by converting it to discrete first and then using it:
2.1 As it is (continuous)

2.2 Converting to discrete first & then using it

and then :

3) We can now see that France, with 485 has the 2nd most number of patents for the year 2013

Q103. How can you MANUALLY assign geographic roles to a dimension from the data pane?

 Edit the config file in My Documents -> MyTableauRepository for a quick fix

 Right click it -> Geographic role -> and then assign the appropriate geographic role

 Edit the data source manually for a quick resolution

 Right click it -> Edit Default properties -> Assign geographic roles

From the data pane, simply right click on the dimension, choose geographic role, and then select the appropriate role as follows:

Q104. If you have a dashboard and are displaying its filter, how can you rearrange it?

 By clicking on the 2 lines on top and dragging the filter.

 By clicking on the dropdown and dragging the filter

 By clicking on the filter title and dragging it.

 By clicking anywhere inside the filter and dragging it.

You can drag the filter by clicking on the 2 lines on top, and then dragging the filter as shown:

Q105. Download the Dataset from: https://drive.google.com/file/d/12AYHfiPWkwBmvH0zbumOURgUX6Az00Rw/view?usp=sharing Using the Time Series Table, create a line chart to show Sales over time. Which Month and Year witnessed the lowest Sales?

 September 2017

 March 2018

 December 2017

 January 2018

Follow the steps to get the correct answer : January 2018

We are talking about dates, so use the Time series sheet as follows:

Next, the following should be your view and clearly, January 2018 is the lowest point:

Q106. True or False: To concatenate fields, they must be of same data type

 True

 False

Yes! To concatenate fields, they must be of same data type. However, there is a workaround which we can use – Type casting. See below:

Here, State and City are Strings, but Postal Code? Nope. It’s an Integer. So we can simply use the STR() function to convert it into a String, and hence the entire equation becomes valid!

Q107. You have cleaned a data source properly, created some calculated fields and renamed some columns. You want to save these changes for future use cases. Which of the following would BEST satisfy this requirement?

 Save it as a .twm file

 Save it as a .twb file

 Save it as a .tds file

 Save it as a .twbx file

After making changes to Data, we can save that new data source as a .tds file. To do so, go to data menu on top and then choose your current connected data source. Then next click on Add to Saved Data sources. This will save all calculated fields, changes to fields etc. It will be saved in My Tableau Repository -> Mydatasources. This will then also appear on Tableau Home Page under saved data sources like SampleSuperStore.
Note: Data source files do not contain the actual data but rather the information necessary to connect to the actual data as well as any modifications you’ve made on top of the actual data such as changing default properties, creating calculated fields, adding groups, and so on.
.twb and .twbx are not the BEST solutions since the questions nowhere mentions that we need to store our workbooks as well.
.twm is a bookmark which contains a single worksheet and are an easy way to quickly share your work.

Q108. Using the Time-series table, create a cross tab showing the Sales for each Item Number-ID, broken down by Assortments, then add Grand totals to the view. Which Item Number ID made the maximum sales across all assortments?

 584

 901

 Correct)

 205

 660

Follow along the steps below:
Drag Assortment and Year ID to the column shelf, and Item Number ID to the row shelf. Next, drag Sales to the Text label to create a cross-tab as below:

Q109. What is the following icon in the Data pane used to do?
Larger image

 View Data

 Clean Data

 Extract Data

 Sort Data

Explanation
View Data allows you to inspect your data in a spreadsheet-like layout. You can view data either for the data source as a whole, or to see the underlying data for an individual mark or a group of marks. In a worksheet, the rows that you see in the View Data window are always scoped to the current selection or the current view.
The View Data window displays as much of the data as possible by default, up to 10,000 rows. Field names are shown as column headers and can be dragged and dropped to change their display order. Click a column header to sort the values in that column.
From the official website:

Q110. The View Data window displays as much of the data as possible by default, up to _______________ rows.

 20,000

 5,000

 10,000

 15,000

Explanation
The View Data window displays as much of the data as possible by default, up to 10,000 rows. This can be increased though, if you wish to.

Q111. What does it imply if a field has a blue background?

 It is continuous

 It is discrete

 It is a dimension

 It is a measure

When you connect to a new data source, Tableau assigns each field in the data source as dimension or measure in the Data pane, depending on the type of data the field contains. You use these fields to build views of your data.
