Which two actions should you perform?

You are the Exchange administrator for your company. Exchange Server 2003 is the messaging system.
The Exchange organization includes a twonode active/active server cluster that provides failover capabilities for each of the two Exchange Virtual Servers (EVSs).
You need to ensure that the cluster will automatically balance the two EVSs evenly across both cluster nodes, as long as both nodes are operational.
You must not remove the existing failover capabilities. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

A.
Configure failover for each EVS.

B.
Configure failback for each EVS.

C.
Configure a single preferred node for each EVS.

D.
Configure a single possible node for each EVS.

E.
Configure the quorum disk resource so that is does not affect the cluster resource group when a failure occurs.

Explanation:
In server clusters, failover is the process of taking resource groups offline on one node and bringing them online on another node.
When failover occurs, all resources within a resource group fail over in a predefined order; resources that depend on other resources
are taken offline before, and are brought back online after, the resources on which they depend. If an individual application in a server
cluster fails (but the node does not), the Cluster service typically tries to restart the application on the same node. If that fails, it
moves the application’s resources and restarts them on another node of the server cluster. This process is called failover When a
node becomes inactive for any reason, the Cluster service fails over any groups hosted by the node. When the node becomes active
again, the Cluster service can fail back the groups originally hosted by the node. The Cluster service fails back a group using the
same procedures it performs during failover. That is, the Cluster service takes all of the resources in the group offline, moves the
group, and then brings all of the resources in the group online. This is called Failback. You can set failback to occur during a specific
time period. It is important to set the failback time because you may not want failback to occur during hours of peak usage.
