What all are true, for replacing the node, rather than first remove and then add?

Exp : When you replace the dead node in the cluster then you should not follow the strategy like first remove the dead node from the cluster and then add a new node to the cluster. Rather you should use the replace node strategy where you would keep the dead node as part of the cluster until the new node is added.
