Are PBI Data & Queries Consuming Enterprise Gateway Server Resources?

Hello Community,

I am looking to implement Enterprise Gateway to connect to my on-prem SQL Server DB queries.  All PBI are using "Imported" methodology (as opposed to DirectQuery).

Two questions:

1. Are all Dashboard datasets cached on the Enterprise Gateway?

2. When user query the Dashboard on PBI Services, are they consuming Enterprise Gateway or SQL Server server resources?

Thank you!
