    A

    Deploy a failover cluster that contains one node in each office.

    B

    Deploy a failover cluster that contains two nodes in each office.

    Company.com has a six-node concurrent resource group with an application that is accessed by  a web connection to the cluster nodes. How is the workload moved to another cluster node during a node failure？（）
    A

     The concurrent application must control the web interface through application monitoring.

    B

     A second resource group will be required to move the web application and IP label to a new node during a node failure.

    C

     The concurrent resource group can support multiple IP labels through IP aliasing so all IP labels are defined in the concurrent resource group.

    D

     The dynamic node priority facility in HACMP will relocate the web application and the IP label，if it is correctly defined in the application start and stop script.
