DRAG DROP
Your network contains four servers that run WindowsServer 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.
Answer: NIC1: do not allow, NIC2: allow, NIC3: allow
Explanation:

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.)
Answer is Correct. Explanation screen shot is incorrect.
This is not correct , as per Greg Shields videos on CBT nugget and Pluralsight (70-412), on the storage network we should not allow Cluster heartbeat communications, and on the other two subnets (Production and Private Cluster) heartbeat can function
Based on this screenshot :
NIC1 : 192.168.1.0 -> Do now allow heartbeat/cluster communication
NIC2 : 192.168.2.0 -> Allow cluster communication (private Cluster subnet, clients are not allowed)
NIC3 : 192.168.3.0 -> Allow cluster communication as well as clients communicating with the cluster interface. This is the production subnet but heartbeat communication should preferably have 2 ways/subnets of doing its job
Based on your own statement: “on the storage network we should not allow Cluster heartbeat communications, and on the other two subnets (Production and Private Cluster) heartbeat can function”, it should be allow, allow and do not allow.

“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”
“Storage
Do not allow cluster network communication on this network”
Based on this i can’t see why you’re saying the correct answer is do not allow, allow, allow…
Forget my previous post, i only realized that image on this question is in different order from my VCE file.
In my VCE file the question looks like this one: http://www.aiotestking.com/microsoft/you-need-to-configure-the-network-settings-for-cluster1-2/
In this case i agree with Alex Chaingun.
@ Alex Chaingun, you are right. Thank you.

The Cluster service, running on each node of the cluster, keeps track of the current state of the nodes within a cluster and determines when a group and its resources fail over to an alternate node. This communication takes the form of messages that are sent regularly between each node’s Cluster service. These messages are called heartbeats.

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
