List of questions
Question 11

Using the dataset provided, create a crosstab showing the Profit of each Region per Year, then add grand totals to the view. What was the total Profit for Canada in 2012 and the total Profit for Canada for 2011 through 2014, respectively?
Explanation:
To reach the correct answer, follow these steps:
1) Drag Order Date (Discrete Year) to the Column shelf, and Region to the Row Shelf as shown:
2) Drag Profit to Text in the Marks Shelf as shown:
3) Click on Analysis as shown -> Totals -> SELECT ROW GRAND TOTALS
The following will be the final view:
You could also Filter by Region to only Focus on Canada, but that's your choice:
THEREFORE,
2012 = 4,888
2011 -> 2014 = 17,817
Question 12

True or False : Bins can be created on dimensions
Explanation:
Bin are a user-defined grouping of numerical data in the data source.
According to the official Tableau documentation: It's sometimes useful to convert a continuous measure (or a numeric dimension) into bins.
Have a look at the following image. When we right click a measure, we get the following options:
However, for a dimension (this is because theDATA TYPEof this dimension is a string:
But what if we have a dimension of typeNUMBER (NUMERIC DIMENSION)? See below:
We can clearly create bins from dimensions too - they just have to be numeric :)

Question 14

Is it possible to use measures in the same view multiple times (e.g. SUM of the measure and AVG of the measure)?
Explanation:
Yes, it is very much possible to use measures in the same view multiple times. For example, refer to the image below:
We are usingBOTHtheSumof the revenue and theAVGof the revenue in the same view!
Question 15

By definition, Tableau displays measures over time as a ____________
Explanation:
Line charts connect individual data points in a view. They provide a simple way to visualize a sequence of values and are useful when you want to see trends over time, or to forecast future values.
Please refer to the images below:
Question 16

Which of the following would you use to connect to multiple tables in a single data source at once?
Explanation:
The data that you analyze in Tableau is often made up of a collection of tables that are related by specific fields (that is, columns). Joining is a method for combining data on based on those common fields. The result of combining data using a join is a virtual table that is typically extended horizontally by adding columns of data.
For example, consider the following two tables originating from a single data source:
We can combine these 2 tables, simply by joining the tables on ID to answer questions like, 'How much was paid in royalties for authors from a given publisher?'. By combining tables using a join, you can view and use related data from different tables in your analysis.
Question 17

What is the minimum amount of RAM recommended for any production use of Tableau Server?
Explanation:
The computer on which you are installing or upgrading Tableau Server must meet the minimum hardware requirements. If the Setup program determines that your computer does not meet the following requirements, you will not be able to install Tableau Server.
These minimum requirements are appropriate for a computer that you use for prototyping and testing of Tableau Server. They apply to single-node installations and to each computer in a distributed installation.
Question 18

Which of the following chart type makes use of 'binned' data?
Explanation:
A histogram is a chart that displays the shape of a distribution. A histogram looks like a bar chart but groups values for a continuous measure into ranges, or bins.
Question 19

True or False: Trend lines can only be used with numeric or date fields
Explanation:
You can show trend lines in a visualization to highlight trends in your data.
To add trend lines to a view, both axes must contain a field that can be interpreted as a number. For example, you cannot add a trend line to a view that has the Product Category dimension, which contains strings, on the Columns shelf and the Profit measure on the Rows shelf.
However, you can add a trend line to a view of sales over time because both sales and time can be interpreted as numeric values.
Question 20

True or False: All rows from both tables are returned in an INNER JOIN
Explanation:
The INNER JOIN keyword selects all rows from both tables as long as there is a match between the columns. Consider 2 tables 'Orders' and 'Customers'.
If there are records in the 'Orders' table that do not have matches in 'Customers', these orders will not be shown!
