- Correct answer : B — Cluster mode A . This is incorrect because in this mode the driver runs on the machine that issued the submit command, so the application would stop if that machine disconnected. B . This is correct because this deploy mode launches the driver process on a node inside the cluster itself, so the application continues running independently of the machine that originally issued the submit command. C . This is incorrect because this mode runs the driver and executors within a single JVM on one machine and is not used for submitting a job to a YARN cluster. D . This is incorrect because this term refers to Spark's built-in cluster manager, not to a deploy mode that controls where the driver process runs. E . This is incorrect because this is not a recognized Spark deploy mode; the deploy mode options control driver placement, not an interactive session type.
