An administrator needs to create a Network Profile for NDB HA VMs spread across three Nutanix clusters. What type of Network Profile is required for…

When creating a Network Profile for NDB HA VMs (e.g., NDB API and Repository VMs) spread across

three Nutanix clusters, the required type is PostgreSQL HA instance managed outside NDB. NDB HA

relies on a PostgreSQL database for its control plane, and in a multi-cluster HA setup, this PostgreSQL

instance must be configured for high availability (e.g., using streaming replication) outside NDB’s

management. The Network Profile must support this external HA instance’s networking

requirements (e.g., VLANs, IP ranges) to ensure connectivity across clusters.

Other options are incorrect:

A . PostgreSQL HA instance managed in NDB: NDB manages database instances, not its own HA

control plane database.

B . PostgreSQL single instance managed in NDB: A single instance lacks HA, unsuitable for multi-

cluster.

D . PostgreSQL single instance managed outside NDB: Lacks HA, insufficient for NDB HA VMs.

Thus, the verified answer is C, aligning with NDB HA architecture.
