第4题：

When scaling Coherence from one to two cache servers， it will not show the same scalability as two to four. Why？（）

• A、 Coherence uses a more efficient TCMP algorithm going from two to four cache servers
• B、 When going from one to two cache servers， object backups are copied across servers so work is doubled，but going from two to four is a fixed amount of work
• C、 Near cache is enabled with a larger quorum thus performance is improved
• D、 all of the above
