The only option that is stored in the Databricks customer’s cloud account is data. Data is stored in the

customer’s cloud storage service, such as AWS S3 or Azure Data Lake Storage. The customer has full

control and ownership of their data and can access it directly from their cloud account.

Option A is not correct, as the Databricks web application is hosted and managed by Databricks on

their own cloud infrastructure. The customer does not need to install or maintain the web

application, but only needs to access it through a web browser.

Option B is not correct, as the cluster management metadata is stored and managed by Databricks

on their own cloud infrastructure. The cluster management metadata includes information such as

cluster configuration, status, logs, and metrics. The customer can view and manage their clusters

through the Databricks web application, but does not have direct access to the cluster management

metadata.

Option C is not correct, as the repos are stored and managed by Databricks on their own cloud

infrastructure. Repos are version-controlled repositories that store code and data files for Databricks

projects. The customer can create and manage their repos through the Databricks web application,

but does not have direct access to the repos.

Option E is not correct, as the notebooks are stored and managed by Databricks on their own cloud

infrastructure. Notebooks are interactive documents that contain code, text, and visualizations for

Databricks workflows. The customer can create and manage their notebooks through the Databricks

web application, but does not have direct access to the notebooks.
