You need to create a Microsoft Power BI file that will be used to create multiple reports. The solution must meet the following requirements: - The file must include predefined data source connections

A Power BI Template (.PBIT) file is designed to fulfill all these requirements. It contains the data model structure, report layout, visuals, formatting, and data source connections, but it does not store any actual data; when opened, it prompts for data source credentials and refreshes the data.

A Power BI Data Source (.PBIDS) file only stores data source connection information and does not include any report structure or formatting.

A Power BI Desktop (.PBIX) file contains the full report, including the data model and all imported data, which violates the requirement that the file must NOT contain any data.

A Power BI Project (.PBIP) is a folder-based structure for source control of a Power BI report and dataset, not primarily a 'no data' template for report creation.
