A watsonx.data administrator wants to add a second Presto engine dedicated to ETL workloads. What is the correct tool to use?

Infrastructure Manager is the administrative control plane in watsonx.data where administrators provision; configure; and manage multiple query engines including dedicated Presto instances for different workload types. The incorrect options ("The watsonx.data SQL console by running ALTER ENGINE statements", "IBM Cloud IAM by assigning the ETL role to an existing engine", "The Spark notebook by creating a new SparkSession with ETL configuration") are distractors that don't fully capture the concept described.
