Companycom is planning to do server consolidation on POWER5. The customer has a test environment, a QA environment and a production environment for two applications. Both the test and QA environments are very small and are only utilized when new releases are being developed and tested. They require less than 1 CPU each. Both production applications require 2 CPUs for day-to-day operation and can require up to an additional 2 CPUs each during abrupt peak requirements. What is the best design for the LPARs?（）

• A、Use micropartitioning for test and QA environments, and DLPAR for the production applications  
• B、Use micropartitioning for test and QA environment, and CPU pooling for the production applications 
• C、Create standard LPARs for all test, QA, and production applications to keep all partitions separate and isolated. 
• D、Create DLPAR partitions for all test, QA, and production applications to keep test from disturbing production environment.
