Which statement best describes how you designate which node remains primary or secondary in an HA pair?

• A. The primary is automatically chosen by the system at boot.
• B. You explicitly configure which node stays primary or stays secondary in the HA settings.
• C. The node with higher IP becomes primary.
• D. Both nodes must be switched manually to change roles.

Answer: (B)

In an HA pair, the roles of primary and secondary are defined by configuration, not by chance or by simple rules like IP or boot order. You explicitly designate which node should remain primary in the High Availability settings, and the other node takes the secondary role. This explicit configuration provides a stable, predictable failover behavior: if the primary fails, the secondary can take over while preserving service continuity. The primary isn’t chosen automatically at boot, nor is it determined by the node’s IP address, and you don’t have to switch both nodes to change roles—changing the HA configuration or triggering a controlled failover allows the roles to be swapped as needed.
