What type of storage location requires an on-premises data gateway for a Power BI dataset?

The correct choice is a shared folder on a local network. This type of storage requires an on-premises data gateway because it is located within the organization’s infrastructure and not on the cloud. The on-premises data gateway acts as a bridge, allowing Power BI to connect securely to data sources that are hosted on local machines or in private networks. This is crucial for maintaining data security and compliance while enabling Power BI to access and refresh the data needed for reports and dashboards.

In contrast, cloud storage options such as OneDrive for Business and a personal OneDrive account, as well as SharePoint Online Team Sites, are directly accessible to Power BI without needing an on-premises gateway. These services are part of Microsoft's cloud offerings and can be connected using the Power BI service, thus eliminating the need for a gateway.
