Which of the following features of Active Memory perform a regular check and cleanup of the status of DIMMs？（）

A.Install the two cards in slots 5 and 6 in the x445.
B.Install the two cards in slots 3 and 5 in the x445 make sure slots 4 and 6 are not occupied.
C.Install an RXE-100 on each x445 and install one card in the x445 and one card in an RXE-100 on each system.
D.Connect an RXE-100 between the two x445s and install one card in each x445 and one card in each side of the RXE-100.

A.The system requires 220V power to enable the upper SMP expansion module.
B.The technician cabled the SMP expansions wrong.
C.The Xcel4 cache needs to be reset in the BIOS because of the addition of the second SMP expansion module.
D.If no hardware licenses keys have been purchased for the processors in the upper SMP expansion module， it will not be activated.

A.CPU，because the database replication process requires a considerable amount of CPU time
B.Memory，because the buffer cache requires a large amount of memory to maintain the data in system memory
C.Disk，because it is important to configure a sufficient number of disks to match the CPU processing power
D.Network，because the data returned to the client from the server can be a large subset of the total database
