NDB High Availability distributes control-plane components across three Nutanix clusters so that a single cluster or site does not become the sole failure domain. For deployments spanning separate data centers or sites, the supported round-trip time between the selected clusters must be less than 25 milliseconds. A two-cluster topology is not supported because the cluster hosting two API servers and two repository servers would remain a single point of failure. Option C is also too restrictive: the three clusters may use AHV or ESXi; they are not required to be three AHV clusters. Consequently, option A is correct. The List B answer of D, which states less than 5 milliseconds, conflicts with Nutanix’s documented HA requirement and has been corrected. Nutanix NDB HA architecture
