Databricks Certified Data Engineer - Associate

Explanation

In Databricks architecture, the Data plane (also known as the compute plane) is where the driver and worker nodes of a Databricks-managed cluster are hosted. Here's why:

• Data Plane: This is the environment where your actual data processing occurs. It contains the compute resources (clusters) that run your Spark jobs, notebooks, and workflows. The driver node coordinates the execution, while worker nodes perform the actual data processing tasks.

• Control Plane: This manages the workspace, user authentication, job scheduling, and cluster management, but does not host the actual compute nodes.

• Databricks Filesystem (DBFS): This is a distributed file system for storing data, not for hosting cluster nodes.

• JDBC data source: This is a connectivity method for accessing external databases, not a location for cluster nodes.

• Databricks web application: This is the user interface for interacting with Databricks, not where cluster compute resources run.

The data plane is typically hosted in your cloud account (AWS, Azure, or GCP) and contains the actual virtual machines that form the Databricks clusters.
