Which two components function in the DB platform architecture’s control plane? (Choose two.)

The Databricks platform architecture is divided into a control plane and a data plane. The control plane contains the backend services that Databricks manages, including the web application, notebook commands, and management of jobs and clusters. Compute Orchestration is the core service within the control plane responsible for managing the lifecycle of compute resources. Unity Catalog is a centralized governance solution whose metastore and services also reside in the control plane, managing metadata and access control for data assets across the platform.

A. Virtual Machines: These are the fundamental compute resources that run in the data plane within the customer's cloud account, not the control plane.
C. Serverless Compute: The actual compute resources for serverless workloads run in a serverless data plane, separate from the control plane that orchestrates them.
D. Compute: This is a general term for the clusters and virtual machines where data processing occurs, which is the primary function of the data plane.

1. Databricks Documentation, "Databricks architecture overview": This document explicitly separates the architecture into two planes. It states, "The control plane includes the backend services that Databricks manages... Notebook commands and many other workspace configurations are stored in the control plane... The data plane is where your data is processed." This supports that orchestration logic (B) is in the control plane, while the actual compute resources (A, C, D) are in a data plane.

2. Databricks Documentation, "What is Unity Catalog?": This source clarifies the location of Unity Catalog. Under the section "The Unity Catalog object model," it states, "The Unity Catalog metastore... is a service managed by Databricks that resides in the control plane." This directly confirms that Unity Catalog (E) is a control plane component.
