Databricks Certified Data Engineer Associate — Question 1

Which of the following is hosted completely in the control plane of the classic Databricks architecture?

Answer options

• A. Worker node
• B. JDBC data source
• C. Databricks web application
• D. Databricks Filesystem
• E. Driver node

Correct answer: C

Explanation

The Databricks web application is the only option that functions entirely in the control plane, managing user interactions and job submissions. The worker node, JDBC data source, Databricks Filesystem, and driver node all operate in the data plane, handling data processing and storage rather than control functions.
