NEW QUESTION 101
By default, what does Tableau do when you connect to a data source?
- A. Creates a live connection to the data
- B. Sorts the data in descending order
- C. Loads your actual file into Tableau
- D. Creates an extract of the data
Answer: A
Explanation:
Before you can build a view and analyze your data, you must first connect Tableau to your data. Tableau supports connecting to a wide variety of data, stored in a variety of places.
By default, when you connect a data source to Tableau, Tableau will create a live connection to the data.
Live connection refers to a data source that contains direct connection to underlying data, which provides real-time or near real-time data. With a live connection, Tableau makes queries directly against the database or other source, and returns the results of the query for use in a workbook. Users can create live connections and then share them on Tableau Server so that other Tableau users can use the same data using the same connection and filtering settings.
NEW QUESTION 102

NEW QUESTION 107
Which of the following is true about 'Incremental refresh' when creating Extracts in Tableau?
- A. They can only be used with large datasets
- B. There is no difference, both are the same when using extracts. They are different when using live connections.
- C. It only adds rows that are new since the previous refresh.
- D. It replaces all of the contents in the extract
Answer: C
Explanation:
Extracts are saved subsets of data that you can use to improve performance or to take advantage of Tableau functionality not available or supported in your original data. When you create an extract of your data, you can reduce the total amount of data by using filters and configuring other limits. After you create an extract, you can refresh it with data from the original data.
When refreshing the data, you have the option to either do a full refresh, which replaces all of the contents in the extract, or you can do an incremental refresh, which only adds rows that are new since the previous refresh.
NEW QUESTION 108
You may create a context filter to:
- A. To create a dependent filter
- B. Create a dependent numerical or top N filter
- C. Improve performance
- D. To replace a data source filter
Answer: B,C
Explanation:
Important question! You cannot use a context filter to replace a data source filter since each filter type has its own use case. Also, a content filter is an Independent filter and all other filters are called dependent since they only process the data that passes through a context filter.
According to the official documentation :

- A. Data source Filter
- B. Context Filter
- C. None of the these
- D. Extract Filter
Answer: B
Explanation:
Explanation
IMPORTANT QUESTION, PAY ATTENTION
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. 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.
NEW QUESTION 115
True or False: Context Filters are executed after Data Source filters
- A. False
- B. True
