Your network contains four servers that run Windows Server 2012 R2.
Each server has the Failover Clustering feature installed. Each server has three network
adapters installed. An iSCSI SAN is available on the network.
You create a failover cluster named Cluster1. You add the servers to the cluster.
You plan to configure the network settings of each server node as shown in the following table.
You need to configure the network settings for Cluster1.
What should you do?
To answer, drag the appropriate network communication setting to the correct cluster
network. Each network communication setting may be used once, more than once, or not at
all. You may need to drag the split bar between panes or scroll to view content.

– Allow cluster network communication on this network. If you select this option and you want the network to be used by the nodes only (not clients), clear Allow clients to connect through this network. Otherwise, make sure it is selected.
– Do not allow cluster network communication on this network. Select this option if you are using a network only for iSCSI (communication with storage) or only for backup. (These are among the most common reasons for selecting this option.)
