A fintech runs its Databricks workspace on classic compute, with all-purpose clusters for interactive notebook work and job clusters for nightly Lakeflow Jobs. During a security review, the cloud architect asks in which cloud account those clusters will run, because that determines network routing and instance policies. Which statement correctly describes how compute is deployed for this workspace?

1. A. Classic clusters run in the customer's cloud account, in the data plane; the Databricks-managed control plane hosts the UI, job scheduling, and APIs ✓ A
2. B. Every deployment runs all of its compute in Databricks-owned cloud accounts, so customer cloud resources never execute any workloads 💬 B
3. C. The data plane is only a metadata layer for the workspace UI, and all cluster workloads execute inside the Databricks control plane 💬 C
4. D. Serverless compute runs inside the customer's VPC, while classic compute runs in Databricks-owned cloud accounts 💬 D

Reveal answer

Correct answer: Classic clusters run in the customer's cloud account, in the data plane; the Databricks-managed control plane hosts the UI, job scheduling, and APIs
