Identifying when a gateway is required

Power BI can directly connect to most cloud-based data sources. If your data source is on-premises, you will need to install and configure an on-premises data gateway. You will not need to know how to install a gateway for the exam. But you will need to know when it is necessary.

The Power BI service will inform you if a gateway is necessary. There is a Gateway connection option on the dataset settings page. If your dataset requires a gateway, this section will inform you that you have not configured your dataset to use an on-premises data gateway.

Test Tip

You will not be able to enable the slider to schedule a refresh if a gateway is required and not set up.
