Which of the following is hosted completely in the control plane of the classic-Databricks architecture?
A
Worker node
B
JDBC data source
C
Databricks web application
D
Databricks Filesystem
E
Driver node
Explanation:
In the classic Databricks architecture, the control plane includes the Databricks web application, which is hosted completely in the control plane. The control plane manages and orchestrates the Databricks workspace, while the data plane (also called the compute plane) includes worker nodes, driver nodes, and the Databricks Filesystem (DBFS). JDBC data sources are external data sources and not part of the Databricks architecture itself.
