You can _______________ your data to combine two or more tables by appending values (rows) from one table to another

A. blend
B. union
C. concatenate
D. join

正解：B

解説：
You can union your data to combine two or more tables by appending values (rows) from one table to another.
To union your data in Tableau data source, the tables must come from the same connection.
For example, suppose you have the following customer purchase information stored in three tables, separated by month. The table names are "May2016," "June2016," and "July2016."

A union of these tables creates the following single table that contains all rows from all tables.

The following are the available Data sources available as of now:
1) Server

2) File

質問 # 48
If you are working with a huge dataset, which of the following are strong reasons to use a context filter?

A. To help clean the data
B. To include only the data of interest
C. Improve query performance
D. To make the context filter a dependent filter

正解：B、C

解説：
By default, all filters that you set in Tableau are computed independently. That is, each filter accesses all rows in your data source without regard to other filters. However, you can set one or more categorical filters as context filters for the view. You can think of a context filter as being an independent filter (Option stating - To create a dependent filter eliminated here). Any other filters that you set are defined as dependent filters because they process only the data that passes through the context filter.
You may create a context filter to:
1) Improve performance - If you set a lot of filters or have a large data source, the queries can be slow. You can set one or more context filters to improve performance.
2) Create a dependent numerical or top N filter - You can set a context filter to include only the data of interest, and then set a numerical or a top N filter.
For example, suppose you're in charge of breakfast products for a large grocery chain. Your task is to find the top 10 breakfast products by profitability for all stores. If the data source is very large, you can set a context filter to include only breakfast products. Then you can create a top 10 filter by profit as a dependent filter, which would process only the data that passes through the context filter.

質問 # 49
Which of the following calculations DO NOT need a quick table calculation?

A. Standard Deviation
B. Moving Average
C. Rank
D. Variance

正解：A、D

解説：
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.

質問 # 50
The option to create bins is available for which type of field?

A. Numeric
B. Boolean
C. Date
D. String

正解：A

解説：
The option to create bins in Tableau is available for numeric fields. Bins allow you to group a series of numeric values into larger segments, which can simplify analysis and help in creating histograms or other visualizations that show the distribution of data. For example, you can create bins to group ages into categories like 0-10, 11-20, etc.

質問 # 51
What are two methods for renaming a field in a visualization? Choose two.

A. From the Data pane, right-click the field and select Replace References.
B. From the Format menu, select Field Labels.
C. From the Data pane, use the field's drop-down menu and select Rename.
D. From the Data pane, click and hold on the field until the name is editable.

正解：C、D

解説：
In Tableau, you can rename a field directly in the Data pane by clicking and holding on the field name until it becomes editable, allowing you to type a new name. Alternatively, you can use the drop-down menu associated with the field in the Data pane and select the "Rename" option. Both methods provide a quick and easy way to change the name of a field without affecting the underlying data structure. The "Format menu" and "Replace References" option do not apply to renaming fields.

質問 # 52
Is it possible to use measures in the same view multiple times (e.g. SUM of the measure and AVG of the measure)?

A. No
B. Yes

正解：B

解説：
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 using BOTH the Sum of the revenue and the AVG of the revenue in the same view!

質問 # 53
Which of the following is a compelling reason to export a sheet in Tableau to a PDF?

A. If we want to dynamically enter parameters to the visualisation.
B. If we want a static view of the visualisation.
C. If we want to interact with the visualisation.
D. If we want to use filters in the visualisation.

正解：B

解説：
Exporting the visualisation gives us a static view of the visualisation.
It is NOT possible to interact with it, use filters, or dynamically enter anything in a visualisation exported PDF.
In Tableau Desktop, you can save views as PDF files rather than printing them as hard copies. You do not need to have Adobe Acrobat installed on your computer.
When you print an individual sheet to PDF, filters in the view are not included. To show filters, create a dashboard containing the sheet and export the dashboard to PDF. (IMPORTANT)

質問 # 54
Which of the following represent a valid method to create a Bullet Graph with the LEAST number of fields possible?

A. using 1 measure
B. using 2 dimensions
C. using 2 dimensions and 3 measures
D. using 2 measures

正解：D

解説：
A bullet graph is a variation of a bar graph developed to replace dashboard gauges and meters. A bullet graph is useful for comparing the performance of a primary measure to one or more other measures. Below is a single bullet graph showing how actual sales compared to estimated sales.
We can create a Bullet graph with just 2 measures! This method requires the LEAST number of fields possible to create this type of chart.
The best way to tackle such questions in the exam is to click the "SHOW ME" button on top right, and hover over the chart we want to create.
In our case, it is a Bullet graph.

Therefore, we need 2 measures at least to create this chart, and 0 or more dimensions.

質問 # 55
What are two outcomes when you drag a continuous date value to the Rows shelf? Choose two,

A. The pill on the Rows shelf is blue.
B. The date part Is displayed as labels.
C. A quantitative axis is shown.
D. The pill on the Rows shelf is green.

正解：C、D

解説：
Dragging a continuous date value to the Rows shelf in Tableau results in a green pill on the Rows shelf, indicating a continuous field. It also results in a quantitative axis being displayed on the visualization.
Continuous fields are used to create axes on charts and can represent a range of values smoothly. This is opposed to discrete date values, which would be represented by a blue pill and typically show headers or labels rather than a continuous axis.

質問 # 56
The row and column shelves contain ___________________

A. Grand Totals
B. Pills
C. Filters
D. Parameters

正解：B

解説：
We can drag fields from the Data pane to create the structure for your visualizations.
The Columns shelf creates the columns of a table, while the Rows shelf creates the rows of a table. You can place any number of fields on these shelves.
These FIELDS are also referred to as PILLS. See below:

A. From the Format menu, configure the Font settings
B. From the Format menu, configure the Field Labels settings.
C. From the Data pane, configure the data type of the field.
D. From the Data pane, configure the number format of the field.
