From the High Availability and Management lesson, the Study Guide states:
"You must configure the HA group name, password, and the virtual IP only on the primary node. After you configure those, you can add the secondary node to the group using the commands shown on this slide."
The hc-slave command (shown as hc-worker for secondary) requires pointing to the Primary Node's HA interface IP , not the cluster virtual IP or the primary node ' s port1.
From the exhibit:
Primary Node port4 (HA interface) = 10.50.1.30
Secondary Node port4 = 10.50.1.40
Primary Node port1 = 10.25.1.30
Cluster Virtual IP = 10.25.1.50
The secondary node must connect to the Primary Node's dedicated HA communication port (port4 = 10.50.1.30) to join the cluster, making Option B the correct answer.
