Study one scenario at a time.

An engineer runs PySpark code from VS Code on a laptop through Databricks Connect. The DataFrame transformations run on a Databricks cluster, yet the rows printed by display() and show() appear in the laptop's terminal. Which statement describes how Databricks Connect works?

Pick an option (optional), then reveal the answer.

1. A

   The engineer must copy results back from the cluster by hand after each action.

2. B

   All Spark computation runs on the laptop; only the files are read from remote storage.

3. C

   The local client sends the Spark plan to the remote cluster for execution and receives the results back.

4. D

   It installs a full copy of the cluster runtime on the laptop and keeps it in sync.
