Specifically, defining primary cluster parameters involves configuring the settings that determine the behavior and performance of the primary cluster, which is the core component of VantageCloud Lake. This includes setting parameters such as the number of nodes, the size of the nodes, and the storage configuration. The other options are not correct. Disabling system features and upgrades is generally not allowed in cloud-based platforms like VantageCloud Lake, as it could compromise the integrity and security of the system. Configuring workloads based on profiles is typically handled by workload management tools, not the VantageCloud Lake Console. Adjusting monitor data collection settings is typically done through monitoring tools, not the VantageCloud Lake Console.
