In an NDB high availability (HA) environment spanning multiple Nutanix clusters, with two clusters running VMware ESXi and one running Nutanix AHV, cross-hypervisor compatibility becomes essential to manage the heterogeneous environment effectively. Nutanix Prism Central is the centralized management platform that provides a unified interface and orchestration capabilities across multiple clusters, regardless of the underlying hypervisor (ESXi or AHV). For NDB HA to function seamlessly across these clusters, Prism Central is required to coordinate cluster operations, manage resources, and ensure consistent policy enforcement, including VM placement, failover, and database management tasks. It abstracts the differences between hypervisors, enabling NDB to operate in a mixed environment.
Option A (Stretched VLANs for all nodes) is incorrect because stretched VLANs address network connectivity, not hypervisor compatibility or NDB HA management.
Option B (NGT - Nutanix Guest Tools) is incorrect as NGT enhances guest VM functionality (e.g., drivers, backups) but does not facilitate cross-hypervisor orchestration for NDB HA.
Option C (Nutanix Prism Central) is correct because it provides the necessary multi-cluster management and compatibility layer for NDB HA across ESXi and AHV.
Option D (VirtlO) is incorrect as VirtIO refers to paravirtualized drivers for VMs, not a component for NDB HA or cross-hypervisor support.
Prism Central’s role ensures that NDB can manage database workloads across diverse hypervisor platforms efficiently.
