Suggested Answer: A,B,E Vote an answer

There are three benefits of using an extract as compared to a live connection to a data source:
* A live connection to a data source can be slow due to network and user traffic, whereas a connection to an extract improves performance. An extract is a snapshot of data that is stored locally on your computer or on Tableau Server. An extract can reduce the load on the data source and speed up queries.
* Extracts are stored in memory (RAM), resulting in faster query performance as compared with live data connections. When you use an extract, Tableau loads the data into memory and optimizes it for analysis.
This allows Tableau to perform calculations and aggregations faster than with live connections.
* Calculated fields perform better in workbooks connected to extracts than in workbooks with live connections to a data source. Calculated fields are customfields that you create using formulas or expressions. When you use an extract, Tableau can process calculated fields more efficiently than with live connections.
