During a presentation on the p5 machines， a customer asks the pSeries technical specialist a question regarding the differences between POWER4+ and POWER5.  In addition to new advanced power management， SMT， and larger L2 and L3 caches in POWER5， which of the following describes some of the key improvements in POWER5？（）

A.Micro-Partitioning support and the L3 controller is now between L2 and main memory.

B.Dynamic partitioning support and the L3 controller is now between L2 and main memory.

C.Micro-Partitioning support and the L3 controller is no longer between L2 and main memory.

D.Dynamic partitioning support and the L3 controller is no longer between L2 and main memory.
