If Node3 fails, App1 will fail over to Node2 automatically.

The correct answer is B. No. App1 will not automatically fail over to Node2 upon Node3 failure, likely because Node2 is not an eligible failover target for App1 or another node is preferred, despite automatic failover being a core cluster feature.

Why each option

App1 will not automatically fail over to Node2 upon Node3 failure, likely because Node2 is not an eligible failover target for App1 or another node is preferred, despite automatic failover being a core cluster feature.

AYes

The statement is false; App1 will not automatically fail over to Node2. While failover is automatic for clustered roles, the specific target node depends on cluster configuration and node eligibility.

BNoCorrect

In a failover cluster, if Node3 fails, App1 will attempt to fail over automatically. However, it will only fail over to Node2 if Node2 is an eligible owner for App1 and is healthy and available. If Node2 is not in the list of possible owners for App1, or if it's currently unhealthy or overloaded, then App1 would not fail over to Node2.
