Because this is a four-node cluster, You can find just one server left not assigned to both server pool. the place that last server gets deployed is determined through the MAX_SIZE server pool parameter of each server pool. If the sum from the values from the MAX_SIZE server pool attribute for every server pool is below the whole number of servers inside the cluster, then the remaining servers remain in the no cost server pool awaiting a failure of the deployed node.
set up community firewalls principles by creating protection lists and implementing them to the suitable subnet.
