A customer has a resource group rg1 configured on a two node cluster with the following policies：The customer has observed the following scenarios as nodes join the cluster during cluster start up. Scenario 1 Node1 joins cluster as first node - rg1 is acquired by Node1 Node2 joins cluster as second node - rg1 ismoved from Node1 to Node2 Scenario 2 Node2 joins cluster as first node - rg1 is acquired by Node2 Node1 joins cluster as second node - rg1 remainson Node2 Which of the following is the reason for this behavior？（）

• A、rg1 is configured with a delayed fallback timer
• B、Settling time policy has not been configured for rg1
• C、Node1 does not have sufficient resources to support rg1
• D、Node2 is the first in the ’Default Node Priority’ list for resource group rg1
