The correct answer is A. HPE VM Essentials is positioned as an HPE virtualization software platform that allows customers to manage both KVM-based HPE VM Essentials environments and VMware-based virtual machines from one operational interface. HPE’s QuickSpecs describe HPE Morpheus VM Essentials Software as a virtualization solution that enables provisioning and management of KVM and VMware-based VMs from a single intuitive interface. This fits the customer’s transition scenario: they are not replacing everything immediately; they want to introduce HPE VM Essentials while continuing to operate existing vSphere workloads on HPE Synergy. Option B is incorrect because the Data Services Connector is used to connect supported HPE systems and services to Data Services Cloud Console; it is not the management plane for both vCenter and HPE VM Essentials. Option C reverses the integration model by implying that vCenter is the primary manager for both platforms. Option D is not a valid management approach for this mixed virtualization requirement.
