How can you add a port rule to the cluster nodes?

You are working for a administrator for ABC.com. The ABC.com network consists of a single
Active Directory domain named ABC.com. All the servers on the network run Windows Server
2003 servers.
You have configured four servers in a network load balancing cluster. You need to enable the
cluster in unicast mode although each server only has one network card. After your configuration,

the NLB cluster has successfully converged.
You discover that you can optimize the use of the cluster by moving a specific application to each
node of the cluster. However for this application to execute, all the nodes of the cluster must be
configured by a Network Load Balancing Port Rule.
When you open Network Load Balancing Manager on one of the NLB nodes, you receive a
message saying that Network Load Balancing Manager is unable to see the other nodes in the
cluster.
How can you add a port rule to the cluster nodes?

A.
By opening Network Load Balancing Manager on a different host.

B.
By creating an additional virtual IP address on the cluster.

C.
By modifying the Network Connection Properties on every host.

D.
By removing each host from the cluster before creating the port rule.

Explanation:
You can configure many Network Load Balancing options through either Network
Load Balancing Manager or the Network Load Balancing Properties dialog box accessed through
Network Connections. However, Network Load Balancing Manager is the preferred method. Using
both Network Load Balancing Manager and Network Connections together to change Network
Load Balancing properties can lead to unpredictable results.
