A FastT Host FC-2 bus adapter， a U320 SCSI adapter， and three 10/100Mb Ethernet adapters have to be installed as optimally as possible.  This is going to be a 24X7 system.  The addition of extra PCI-cards is a major consideration as well.  Based on the following， what is the best configuration？（）
（1）Slot 1  66MHz  Bus 1      
（2）Slot 2  66MHz  Bus 1      
（3）Slot 3 100MHz  Bus 2      
（4）Slot 4 100Mhz  Bus 2      
（5）Slot 5 133Mhz  Bus 3      
（6）Slot 6 133Mhz  Bus 3

A.It places frequently accessed data close to the processor to help deliver faster performance.
B.It replaces L3 cache memory.
C.It speeds up processor performance by purging the current set of instructions and freeing them up to work on the next set of instructions.
D.It allows the system to address more than 16GB of memory.

A.With XA-32 architecture， addressing more than 64GB of RAM can be installed.
B.The amount of memory should be balanced across ports for best performance.
C.All DIMM slots should be populated in numerical order - slot 1 before slot 2， slot 2 before slot 3， etc.
D.All even number DIMM slots should be populated before odd number DIMM slots.

A.Begin with a dual DP x445 and scale in the same chassis
B.Begin with a dual MP x445 and scale in the same chassis
C.Begin with a dual DP x445 and scale out in an extra chassis
D.Begin with a dual MP x365 and scale to a different machine
