When your WebLogic Server solution needs to be scaled out with additional capacity and you  Don’t want to add additional hardware, which three techniques should you us?（）

A.Assign more than one managed server to a physical hardware that allows better CPU  utilization
B.Assign more than one application to one managed server to better utilize threads within a single JVM process
C.Assign the same application to more than one managed server to load balance requests  between servers
D.Assign the same heap size to the managed server across the cluster for easier control of  memory footprint  
E.Create a virtualized environment with hypervisor for an easier solution
