An administrator manages an multi-cluster NDB instance with HA enabled. After failure, more than one API server VM is down. How should the administrator restore full functionality?

Question

Options

• ARestart all database server VMs as NDB HA only tolerates single API server failure.
• BManually distribute connections across remaining clusters.
• CCall Nutanix support to reset all API server connections.
• DEnsure at least one API server VM is online; the rest will recover automatically.

Explanation

In a multi-cluster NDB instance with HA enabled, the NDB architecture includes multiple API server VMs to ensure availability. If more than one API server VM is down after a failure, the administrator should ensure at least one API server VM is online. NDB's HA design tolerates multiple API server failures as long as one remains operational, and the remaining VMs will recover automatically through the HA failover mechanism. This leverages Nutanix's distributed architecture and self-healing capabilities to restore full functionality without manual intervention beyond ensuring one VM is running.
