You want to leverage resource consumer groups when using the Scheduler. Which Scheduler object uses resource plans directly?

Answer: B

Explanation: You create a job class with CREATE_JOB_CLASS and specify a resource consumer group with the RESOURCE_CONSUMER_GROUP parameter. You can also specify a resource plan with CREATE_WINDOW. A is incorrect because you cannot directly link a lightweight job with a consumer group. C is incorrect because job chains only specify conditional execution and sequencing among a set of related jobs. D is incorrect because you cannot directly associate a program with a resource plan or resource consumer group
