1. What Failover and Failback terms mean in Windows Cluster?

Failover: Failover is the process of moving a group of resources from one node to another in the case of a failure. For example, in a cluster where Microsoft SQL Server is running on node A and node A fails, SQL Server automatically fails over to node B of the cluster.

Failback: Failback is the process of returning a resource or group of resources to the node on which it was running before it failed over. For example, when node A comes back online, SQL Server can fail back from node B to node A.
