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 manages the cluster and orchestrates tasks but doesn't directly host the worker nodes, JDBC data sources, Databricks Filesystem (DBFS), or driver nodes. The Databricks web application, on the other hand, is hosted entirely within the control plane, providing a user interface for cluster management, job execution, and other administrative tasks.
