An enterprise has three nodes： -Node ’A’ is a production database， -Node ’B’ is a production  Application server， and -Node ’C’ is a test and development node. Node ’C’ is used by six programmers to develop and the production application as business critical and would like to make it highly available with HACMP. Application development and testing is not business critical.  Which of the following describes the best solution？（）  

• A、 There is not an adequate solution because HACMP should not be configured in this environment without a dedicated standby node.
• B、 Nodes ’A’ and ’B’ should be configured in a cluster with mutual fallover of two cascading resource groups to provide both nodes will deliver acceptable response time with both resource groups.
• C、 Nodes ’A’ and ’C’ should be configured in one cluster， and Nodes ’B’ and ’C’ in another cluster to prevent both the database and application server from falling over to Node ’C’ at the same time.

You are a network administrator for your company. You install Windows Server 2003 on two servers named Server1 and Server2. You configure Server1 and Server2 as a two-node cluster.   You configure a custom application on the cluster by using the Generic Application resource， and you put all resources in the Application group. You test the cluster and verify that it fails over properly and that you can move the Applications group from one node to the other and back again.   The application and the cluster run successfully for several weeks. Users then report that they cannot access the application. You investigate and discover that Server1 and Server2 are running but the Application group is in a failed state.   You restart the Cluster service and attempt to bring the Application group online on Server1. The Application group fails. You discover that Server1 fails， restarts automatically， and fails again soon after restarting. Server1 continues to fail and restart until the Application group reports that it is in a failed state and stops attempting to bring itself back online.   You need to configure the Application group to remain on Server2 while you research the problem on Server1.   What should you do？  （）

• A、 On Server2， configure the failover threshold to 0.
• B、 On Server2， configure the failover period to 0.
• C、 Remove Server1 from the Possible owners list.
