In an extract, what are three differences between a full refresh versus an incremental refresh? (Choose three.)
In a full refresh, the extracted data is fully replaced with the data from the underlying data source, which can be time-consuming and usually runs slower. An incremental refresh, on the other hand, is designed to update the extract by adding only new rows of data, making it generally faster. Thus, the key differences between full and incremental refreshes are: a full refresh's replacement of all data versus the addition of only new rows, and the associated speed differences.

B. A full refresh is usually very slow. An incremental refresh can take less time. C. A full refresh replaces all the extracted data with the data in the underlying data source. D. An incremental refresh only adds rows that are new
