PL-300 Prepare the data Practice Question
You are connecting to an Excel workbook stored in Microsoft SharePoint Online. You want to refresh the data in Power BI service without manual intervention. Which type of gateway is required?
⚠ Common exam trap
The trap here is that candidates mistakenly assume any Excel workbook refresh requires a gateway, but the critical distinction is whether the file is stored on-premises (e.g., a network share) versus in a cloud service like SharePoint Online or OneDrive for Business.
Answer choices
Why each option matters

Correct answer & explanation
✓
No gateway is required
When connecting to an Excel workbook stored in Microsoft SharePoint Online, the data source resides entirely in the cloud. Power BI service can directly access SharePoint Online via its cloud-to-cloud connectivity using the same Microsoft Entra ID authentication context. Therefore, no on-premises data gateway is required for scheduled refresh because the data never traverses an on-premises network.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
On-premises data gateway (standard mode)
Why it's wrong here
The standard-mode on-premises data gateway is designed to bridge the Power BI service with data sources that live inside a corporate network, such as SQL Server, file shares, or Windows-based services. SharePoint Online, however, is a cloud SaaS offering with HTTPS endpoints that the Power BI service can reach directly. Using a standard gateway here would add an unnecessary on-premises dependency and a potential point of failure, while providing no benefit for a cloud-hosted workbook.
- ✗
On-premises data gateway (personal mode)
Why it's wrong here
The personal-mode gateway was a per-user, single-machine tool intended for refreshing on-premises data sources in a user's local environment. Microsoft has deprecated personal mode for cloud refresh scenarios, so it is no longer a supported option for any dataset. Even if it were still active, it would not apply to SharePoint Online because the gateway's role is to expose on-premises sources, and SharePoint Online is already accessible directly from the Power BI cloud service.
- ✓
No gateway is required
Why this is correct
No gateway is required because SharePoint Online is a cloud data source that the Power BI service can connect to natively. During refresh, Power BI authenticates directly to SharePoint Online using the stored credentials (typically OAuth or an organizational account) and retrieves the Excel workbook through SharePoint's cloud APIs. The entire refresh operation runs in the cloud, eliminating the need for any on-premises gateway infrastructure or a local machine being online.
- ✗
Virtual network (VNet) gateway
Why it's wrong here
A virtual network (VNet) gateway is a network component used to establish secure VPN or ExpressRoute connectivity between an Azure virtual network and other networks. It is relevant only for data sources that reside inside an Azure VNet or require private IP-based routing, such as a SQL Server on an Azure VM. SharePoint Online is a multi-tenant SaaS service hosted by Microsoft, not inside a customer's VNet, so this gateway type cannot be used to reach it and is entirely irrelevant to the scenario.
