HPE Private Cloud AI Users want to run interactive Spark applications from notebook servers running...

B is correct. Livy provides a REST-based service for creating and managing interactive Apache Spark sessions. In HPE AI Essentials, notebook users who need interactive Spark execution rely on Livy so that notebook-side Spark magic or client commands can submit code to a managed Spark session without embedding a full Spark cluster process inside the notebook itself. Therefore the administrator should ensure Livy is installed and available through the platform’s Tools & Frameworks administration.

Option A is unnecessary because the platform can provide the supported notebook-to-Spark integration once Livy is present; simply building a custom image does not establish the backend session service. Option C assumes that an image name creates Spark connectivity, which it does not. Option D confuses the Spark Operator, used for Kubernetes-managed SparkApplication resources, with the interactive session mechanism requested in the question.

The exam distinction is between batch and interactive Spark. Spark Operator is well suited to declarative Spark applications; Livy enables interactive sessions from notebooks.
