What should you configure?

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 Failover Clustering feature installed. The servers are
configured as nodes in a failover cluster named Cluster1.
Cluster1 hosts an Application named App1.
You need to ensure that Server2 handles all of the client requests to the cluster for App1.
The solution must ensure that if Server2 fails, Server1 becomes the active node for App1.
