So what action should you perform to achieve this goal? （）A、You should alter the default resource pool and set the MAX_CPU_PERCENT option to 80. Then assign this resource pool to the workload group used by SQL Server Management Studio. B、First, you should create a new resource pool and set the MAX_CPU_PERCENT option to 20. Then assign this resource pool to the workload group used by SQL Server Management Studio. C、You should alter the default resource pool and set the MAX_CPU_PERCENT option to 20. Then assign this resource pool to the workload group used by the mission-critical applications. D、First, you should create a new resource pool and set the MAX_CPU_PERCENT option to 80.
