Where are new data sources added in the data pane?
New data sources can be created from the Data menu or the drop down menu from the icon next to the Data Source's name
257
can you define relationships between published data sources?
NO
258
can you define relationships based on geographic fields?
NO
259
what does an incremental refresh of an extract do?
only includes new rows since the previous refresh.
260
why may it be useful to use parameters when creating calculations?
Rather than manually editing the calculation (and all dependent calculations), you can use a parameter. Then when you want to change the value, you open the parameter control, change the value, and all calculations that use that parameter are updated.
261
what data combination method should you Use when combining data from different levels of detail
relationship
262
relationships are to ______ tables as Joins are to ________tables
relationships are to logical tables and joins are to physical tables
263
When using a cross-database join, data integration results at the _____ level,
row
264
When making complex changes to filters on a dashboard, which animation type should you use?
Sequential Animations
265
What types of reference lines can you add in tableau?
table, pane, and cell
266
A __________ _______________ _________________ is a user-defined data subset from a data source.
tableau data extract
267
what are partitioning fields?
The dimensions that define how to group the calculation (the scope of data it is performed on)
268
How do dynamic sets work?
The members of a dynamic set change when the underlying data changes. Dynamic sets can only be based on a single dimension.
269
how do fixed sets work?
The members of a fixed set do not change, even if the underlying data changes. A fixed set can be based on a single dimension or multiple dimensions.
270
How do you relate tables across different databases?
they must be added as data connections within the same data source, not a new data source.
271
T/F The Highlighting action can be disabled for the entire workbook.
True - From the toolbar the Highlighting action can be disabled for the entire workbook.
272
what data combination should you Use when you want to add more rows of data with the same column structure
Union
273
What is the condition tab for when filtering on dimensions?
Use the Condition tab in the Filter dialog box to define rules to filter by. For example, in a view showing the average Unit Price for a collection of products, you may want to only show the Products that have an average unit price that is greater than or equal to $25. You can use the built-in controls to write a condition or you can write a custom formula.
274
what are some possible downfalls or should be considerations when using physical tables?
When using the Physical Tables option, other options to help reduce the data in your extract, like extract filters, aggregation, Top N and Sampling are disabled
275
if you want to rename a dimension what can you do?
You can not rename the original dimension; but you can create a duplicate and rename that to achieve this
276

TRUE
285
T/F Calculated fields, sets, and or parameters are contained in a TDE file?
TRUE
286
T/F Data from different sources cannot be used in a pivot?
TRUE
287
T/F Sets are fields created on existing dimensions.
TRUE
288
T/F Combined sets allow you to compare multiple sets to one another to determine intersections or differences across the sets.
TRUE
289
T/F Context filters improve performance when the data source is large.
TRUE
290
T/F Table calculations are performed locally by tableau.
TRUE
291

TRUE
292
T/F when using Min() or MAX() if either argument is null then the function returns null.
TRUE
293
T/F LOD calcs use data source level queries.
TRUE
294
T/F Forecasting is not supported for multidimensional data sources.
TRUE
295
Create a calculation that combines Month(formatted as Date in data pane) and Year (formatted as an integer in data pane) into a date field. Set the date to be the first of the month for the specified date and year so that for example “May” and “2018” becomes May 1st, 2018.
MAKEDATE([Year],int([Month]),1)
296
