DRAG DROP
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 or networks. 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.

I believe the answer should be:
Cluster Network 1: Do not allow cluster network communication on this network
Cluster Network 2: Allow cluster network communication on this network.
Cluster Network 3: Allow cluster network communication on this network.
Jim,
The answer is correct.
The question is asking which network will be used for cluster resources communication only.
NIC1 and NIC2 are used for cluster resources heartbeat traffic.
Sorry Ebrahimkali,
i’m agree with Jim
If you use a network for iSCSI (storage), do not use it for network communication in the cluster. (eg. https://technet.microsoft.com/en-us/library/cc725775.aspx)
In the table Cluster NW1 is for iSCSI SAN traffic only … only meen only
So Cluster NW1 : Do not, Cluster NW2 : Allow, Cluster NW3 : Allow
🙂
Another vote for Jim:
NIC 1 Do Not allow
NIC 2 Allow
NIC 3 Allow
its allow allow do notallow all over the net. is jimmm right???
It should be Do not allow, allow, allow according to this TechNet post.

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.)
After giving much thought to this apparently easy question, I found this link:
https://technet.microsoft.com/en-us/library/dn550728.aspx
wich recommends :
Cluster1 : Do not allow cluster network communication (it’s storage)
Cluster2 : Allow cluster network communication (Heartbeat is light traffic)
Cluster3 : Allow cluster network communication on this network
according to what I read on technet, the answer is correct…
Network Type/Recommended Setting
Management
Both of the following:
Allow cluster network communication on this network
Allow clients to connect through this network
Cluster
Allow cluster network communication on this network
Note
Clear the Allow clients to connect through this network check box.
Live migration
Allow cluster network communication on this network
Note
Clear the Allow clients to connect through this network check box.
Storage
Do not allow cluster network communication on this network
Replica traffic
Both of the following:
Allow cluster network communication on this network
Allow clients to connect through this network
