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.
