Your network contains an Active Directory domain named contoso.com.
The domain contains two member servers named Server1 and Server2. All servers run Windows
Server 2012 R2. Server1 and Server2 have the Network Load Balancing (NLB) feature installed.
The servers are configured as nodes in an NLB cluster named Cluster1.
Port rules are configured for all clustered applications.
You need to ensure that Server2 handles all client requests to the cluster that are NOT covered
by a port rule.
What should you configure?
A.
Affinity-None
B.
Affinity-Single
C.
The cluster quorum settings
D.
The failover settings
E.
A file server for general use
F.
The Handling priority
G.
The host priority
H.
Live migration
I.
The possible owner
J.
The preferred owner
K.
Quick migration
L.
The Scale-Out File Server
Explanation:
http://technet.microsoft.com/en-us/library/bb742455.aspx
This parameter specifies a unique ID for each host.
The host with the lowest numerical priority among the current members of the cluster handles all of the cluster’s network traffic that is not covered by a port rule. You can override these priorities or provide load balancing for specific ranges of ports by specifying rules in the Port rules tab of the Network Load Balancing Properties dialog box.
If a new host joins the cluster and its priority conflicts with another host in the cluster, the host is not accepted as part of the cluster. The rest of the cluster will continue to handle the traffic as before. A message describing the problem is written to the Windows event log. For more information on error logging and cluster operations, see How Network Load Balancing works, Event logging, and Error detection and handling.
G. The host priority
Remember the difference between Host Priority and Handling Priority. Host Priority
determines which server in an NLB cluster receives traffic that is not covered by a port rule.
Handling Priority is a custom server priority value used for traffic covered by a port rule
but assigned Single Host filtering mode.

The correct answer is G. The Host Priority
You need to ensure that Server2 handles all client requests to the cluster that are NOT covered by a port rule.
The handling priority essentially overrides the host priority for the port range and allows different hosts to individually handle all client traffic for specific server applications.
Each cluster host is assigned a unique host priority in the range of 1 to 32, where lower numbers denote higher priorities. The host with the highest host priority (lowest numeric value) is called the default host. It handles all client traffic for the virtual IP addresses that is not specifically intended to be load-balanced. This ensures that server applications not configured for load balancing only receive client traffic on a single host. If the default host fails, the host with the next highest priority takes over as default host.
—————–
Network Load Balancing uses port rules to customize load balancing for a consecutive numeric range of server ports. Port rules can select either multiple-host or single-host load-balancing policies.
With multiple-host load balancing, incoming client requests are distributed among all cluster hosts, and a load percentage can be specified for each host. Load percentages allow hosts with higher capacity to receive a larger fraction of the total client load.
Single-host load balancing directs all client requests to the host with highest handling priority. The handling priority essentially overrides the host priority for the port range and allows different hosts to individually handle all client traffic for specific server applications. Port rules also can be used to block undesired network access to certain IP ports.
