Explanation:
Box 1: No
In the General settings for App1 we see only Node1 and Node2 listed as Preferred Owners.
Note: Description
The Set-ClusterOwnerNode cmdlet specifies which nodes can own a resource in a failover cluster or specifies the order of preference among owner nodes for a clustered role, or resource group.
The settings that control the possible or preferred owners affect the way the cluster responds to the failure of a resource or a clustered role.
Box 2: No
In the Advanced Policies settings for App1 we the three Possible Owners: Node2, Node3, and Node4.
The cluster would fail over to Node4, the next node.
Box 3: No
The Preferred Owners are Node1 and Node2.
The failback will be to one of the Preferred Owners, not to Node3.
