You can _______________ your data to combine two or more tables by appending values (rows) from one table to another
- A. join
- B. concatenate
- C. blend
- D. union
Answer: D
Explanation:
Explanation
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.
NEW QUESTION 88
True or False: When you drag additional tables to the logical layer canvas, Tableau automatically attempts to create the relationship based on existing key constraints and matching fields to define the relationship. If it can't determine the matching fields, then relating these tables is not possible.
- A. False
- B. True
Answer: A
Explanation:
Tables that you drag to the logical layer of the Data Source page canvas must be related to each other. When you drag additional tables to the logical layer canvas, Tableau automatically attempts to create the relationship based on existing key constraints and matching fields to define the relationship. If it can't determine the matching fields, you will need to select them.
If no constraints are detected, a Many-to-many relationship is created and referential integrity is set to Some records match. These default settings are a safe choice and provide the most a lot of flexibility for your data source.

NEW QUESTION 93
If you are working with a huge dataset, which of the following are strong reasons to use a context filter?
- A. To make the context filter a dependent filter
- B. Improve query performance
- C. To include only the data of interest
- D. To help clean the data
Answer: B,C
Explanation:
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.

NEW QUESTION 96
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?
- A. Save it as a .twb file
- B. Save it as a .twbx file
- C. Save it as a .tds file
- D. Save it as a .twm file
Answer: C
Explanation:
Explanation
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.
NEW QUESTION 97
Which of the following are the options to export the data used to build the view / visualisations?

You can export the data in a Tableau data source, including all or part of the records from your original data.
Alternatively, you can export only the portion of data used to generate the view.
Since the question mentions the data used to build the view, we'll focus on that :
*Export data in the view to Microsoft Access or .csv*
Export the data that is used to generate the view as an Access database (Windows only) or .csv file (Mac only).
1) In Tableau Desktop, select Worksheet > Export > Data.
2) Select a location and type a name for your Access database or .csv file.
3) Click Save.
4) If you're on Windows, the Export Data to Access dialog box displays to give you the option to immediately use the new Access database and continue working in Access without interrupting your work flow.
