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
