Explanation
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
