Answer: Databricks Web Application

The correct answer is the Databricks Web Application. The control plane in Databricks architecture includes backend services managed by Databricks in its own cloud account, such as notebook commands and workspace configurations, which are encrypted at rest. The Databricks Web Application is part of these services. In contrast, the data plane, managed by the customer's cloud account, is where data resides and is processed. Features like SQL Endpoint and DLT compute use shared compute in the control plane.
