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.
