Force a resource to fail over to another node and ensure it does not return to the previous node. Provide necessary commands.A. See the Explanation for Solution. Explanation: 1. Move resource manually: sudo pcs resource move VirtualIP node2 2. Prevent automatic failback: sudo pcs property set cluster-recheck-interval=5min 3. Verify movement restrictions: sudo pcs resource show VirtualIP
