B. Country
C. Address

質問 # 121
Our use case states that we need to create a set showing the Bottom 10 products by Profit in each Region. Which of the following filter types should you apply on Region?

A. Dimension Filters
B. Extract Filters
C. Measure Filters
D. Context Filters

正解：D

解説：
The beauty of context filters is that according to Tableau's Order of Operations, they are executed before Sets.

This means that based on what Region's you've selected - Tableau will first only preserve the rows for those Regions. THEN, after this it will compute the Set , i.e , Bottom 10 products in each Region.
1) First let's create a set to compute the Bottom 10 Products by Profit.

2) Next, take region on the Rows Shelf followed by the Set we just created. Drag Region and the Set to the Filters Shelf as well.

3) Now, try to only visualize the data for the South Region:

4) The problem right now is that Tableau is computing the Set first (Bottom 10 Products), and then applying the Dimension Filter - South Region and hence these values are incorrect. Note how these aren't even 10 products, but rather just 8. To fix this, simply add Region to Context:

Upon doing this, we get the correct answer as :

質問 # 130
Suppose you create a bar chart by dragging a dimension to the Column shelf and a measure to the Rows shelf. Which of the following would create a stacked bar chart?

A. By dragging another measure to Color on the Marks card
B. By dragging another dimension to Color on the Marks card
C. By dragging another measure to the Columns shelf
D. By dragging another dimension to the Rows shelf

正解：B

解説：
Very important question for the exam and appears quite a lot too.
The correct answer is - By dragging another dimension to Color on the Marks card.

This is what the question says we have already created. Now to convert this into a Stacked bar chart, we will drop another dimension on Color in the Marks card.

The rest won't create stacked bar charts, and hence are incorrect choices. The best way to answer such questions on the real exam is to quickly do what the options say and see if they satisfy the requirements in the question.

質問 # 131
Which of the following are valid ways to show Mark Labels in the visualisation?

A. Click on Analysis in the Menu bar and choose Show Mark Labels

D. Click on the Show mark labels icon in the Toolbar

正解：A、B、D

解説：
Explanation
The following showcase how you can show mark labels. Using the Sample Superstore dataset:

質問 # 133
What do the colours Blue and Green represent in Tableau?

A. Continuous and Discrete
B. Dimensions and Measures
C. Discrete and Continuous
D. Measures and Dimensions

正解：C

解説：
Important question! If you selected Dimension and Measure, don't worry! It is a very common mistake. But we're here to learn aren't we?
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.

質問 # 134
True or False: To concatenate fields, they must be of same data type

A. True
B. False

正解：A

解説：
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!

質問 # 135
By definition, Tableau displays measures over time as a ____________

A. Line
B. Bar
C. Stacked Bar
D. Packed Bubble

正解：A

解説：
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.
