A customer has an HMC-managed Power Systems server with 6 partitions. Four production partitions are subject to varying workloads throughout the day, and two are used for development and testing. The production applications have different licensing limitations on the number of physical cores that may be used. The development partitions can use no more than 1 core. The customer would like to dynamically optimize processor utilization within the licensing limits, with minimal operator intervention. Which of the following meets the customer requirement?（） ["Define the production partitions' maximum CPU to the licensing limitations. Define the development\/test partition maximums to one core. Configure each partition to be capped.","Define the production partitions' maximum CPU to the licensing limitations. Define the development\/test partition maximums to one core. Configure each partition to be uncapped.","Define the production partitions' maximum CPU to the licensing limitations. Define the development\/test partitions to use no more than one core. Configure the HMC scheduler to dynamically assign processors among the pools over a day.","Create a shared processor pool for each production partition, with the maximum processor limit set to the licensing limit for the application in the pool. Assign the development and testing partitions to a processor pool with a maximum of 1 core. Configure each partition to use uncapped processing."]
