   A data platform team is designing a solution that must support concurrent writes from multiple applications to the same table, enforce a common schema, and allow auditors to see historical versions of the data. They also need to ensure that only authorized users can access the table. Which combination of components best meets all these requirements?

   • ADelta Lake for storage and workspace-local metastore for access control
   • BUnity Catalog for storage and Delta Lake for access control
   • CDelta Lake for ACID transactions, schema enforcement, and time travel; Unity Catalog for access control
   • DParquet files with a Hive metastore for schema and access control

Which architectural component should be configured to meet this requirement?

   • AConfigure the data plane to be hosted in the customer's cloud account, with the control plane managed by Databricks.
   • BEnable Unity Catalog to isolate the data plane from the control plane.
   • CDeploy the workspace in the control plane and configure the data plane to use a customer-managed VPC.
   • DUse a serverless compute model so that all processing occurs in the Databricks-managed control plane.
