Exam Certified Data Engineer Associate topic 1 question 3 discussion

I disagree with this answer. I think its the databricks web app that is always in the control plane

C. Databricks web application In the classic Databricks architecture, the control plane includes components like the Databricks web application, the Databricks REST API, and the Databricks Workspace. These components are responsible for managing and controlling the Databricks environment, including cluster provisioning, notebook management, access control, and job scheduling. The other options, such as worker nodes, JDBC data sources, Databricks Filesystem (DBFS), and driver nodes, are typically part of the data plane or the execution environment, which is separate from the control plane. Worker nodes are responsible for executing tasks and computations, JDBC data sources are used to connect to external databases, DBFS is a distributed file system for data storage, and driver nodes are responsible for coordinating the execution of Spark jobs.

In the classic Databricks architecture, the Databricks web application (which includes the Databricks user interface, job scheduling, and management components) is hosted entirely in the control plane. This control plane is managed by Databricks and contains the user-facing services and APIs that allow users to interact with the Databricks environment. Here’s why the other options don’t fit: A. Worker node and E. Driver node: Both the driver and worker nodes are part of the data plane, where actual data processing occurs. B. JDBC data source: This is external to Databricks, typically hosted wherever the source database resides, and does not exist within the control plane. D. Databricks Filesystem (DBFS): While DBFS metadata might be managed by the control plane, the actual data is stored in the data plane (often within the customer’s cloud account, such as in AWS S3 or Azure Data Lake Storage).

The control plane in the classic Databricks architecture is responsible for managing the Databricks workspace, user and group management, and cluster management, among other things. The Databricks web application is a part of the control plane that enables users to interact with the workspace, create and manage clusters, and work with notebooks, jobs, and data. Worker nodes and driver nodes are part of the data plane, which is responsible for executing data processing tasks. JDBC data sources and the Databricks Filesystem are services that are used by both the control plane and the data plane.

C. Databricks web application The Databricks web application, which provides the user interface for interacting with Databricks, is hosted entirely in the control plane. It allows users to manage and monitor their clusters, notebooks, and jobs, among other functionalities. The other components mentioned are associated with the compute layer in the classic Databricks architecture: A. Worker node: Worker nodes are responsible for executing the actual computations and processing the data. B. JDBC data source: A JDBC data source refers to an external database or data source accessed through the Java Database Connectivity (JDBC) interface. It is typically located outside of the control plane. D. Databricks Filesystem: The Databricks Filesystem (DBFS) is a distributed file system that stores and manages data within the compute layer. E. Driver node: The driver node is responsible for coordinating the execution of tasks across the worker nodes and managing the user session.

C is correct

C is correct

its "C" - Control plane has Databricks web application

Its C. other options, such as worker nodes, JDBC data sources, Databricks Filesystem (DBFS), and driver nodes, are typically part of the data plane or the execution environment, which is separate from the control plane.

The answer is C! Accordinglu with the Databricks documentation, a cluster consists of one driver node and zero or more worker nodes, by default the driver node uses the same instance type as the worker node.

Who decide the correct answer on this website ? CertiIQ says C ; ITExams says E.... For me it's C

Nodes are on the Data Plane. I think the Web App is the only one in the Control Pane.

C is correct

Answer is C: https://docs.databricks.com/en/_images/databricks-architecture-aws.png

E.Driver Node , is the correct answer. In the classic Databricks architecture, the control plane includes components responsible for managing and coordinating the execution of tasks. The driver node is part of the control plane, and it handles the coordination and execution of the overall Spark application.

Webapplication always resides in Control Plane

C is correct
