You plan to create several datasets by using the Power BI service. You have the files
configured as shown in the following table.
Data 1 - TSV
Data 2- XLSX
Data 3 - XML
Data 4 - CSV
Data 5 - JPG
You need to identify which files can be used as datasets. Which two files should you identify?
Data 1
Data 2
Data 3
Data 4
Data 5
Set Data Connectivity mode to DirectQuery.
(DirectQuery: No data is imported or copied into Power BI Desktop. For relational
sources, the selected tables and columns appear in the Fields list. For multi-dimensional
sources like SAP Business Warehouse, the dimensions and measures of the selected
cube appear in the Fields list. As you create or interact with a visualization, Power BI
Desktop queries the underlying data source, so you're always viewing current data.)
2 and 4
a) TSV is not supported via Power BI Service, and in question it clearly says "by using
Power BI Service".
b) XLSX 3 gb will not work for Pro licence, but it will work for Premium licence. In
question there is no mention about licence type so this option will work for some
customers, for some not. Partially correct.
c) XML is not supported via Power BI Service, and in question it clearly says "by using
Power BI Service".
d) CSV, same as xlsx 3gb, it will work for Premium licence. Partially correct.
e) JPG is not suported via Power BI Service.
For XML Table (.xml) or text (.txt) files, you must load that data into an Excel or Power BI
Desktop file first. You can then import the Excel or Power BI Desktop file into Power BI
Service.
There's a 1-GB limit for datasets stored in Shared capacities in the Power BI service. If you
need larger datasets, you can use Power BI Premium
To change data source values dynamically

These parameters are different from the "What-If" parameters created in the Power BI
Desktip front-end.)
, Data Gateway
(Data Gateways are required for on-premises data sources, like SSAS Tabular live
connections.)
