    An HACMP cluster has three nodes of unequal size. The largest node is Node ’A’. The primary application on Node ’A’ has two components. One component is memory intensive， the other is IO intensive. Nodes ’B’ and ’C’ are running web servers and databases that access information produced by applications on Node ’A’. The customer requires the most performance from the primary application and wants all nodes available for fallover processing.  Which of the following is the best solution for meeting the customer requirements？（）
    A

     Use nodes of equal size.

    B

     Create multiple resource groups and use loadlever.

    C

     Use dynamic node priority to manage resource groups.

    D

     Use an ordered list to manage resource group fallover.

    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.

    D

     Nodes ’A’， ’B’， and ’C’ should be configured in a cluster with Node ’C’ the hot standby for both the database and application server resource groups. Workload Manager （WLM） must be configured on database and application developers from over utilizing the CPU resources.
