Which of the following is a side effect of extensive usage of swap space?

• A.The memory may become fragmented and slow down the access to memory pages. However, this can be kept to a minimum by the regular use of memfrag -d.
• B.Applications need to restart because their virtual memory addresses change to reflect memory relocation to the swap address area.
• C.Since processes always exist completely in either RAM or swap, regular RAM may become unused if the kernel does not move processes back from the swap space to memory.
• D.The root filesystem may become full because swap space is always located on the system root partition.
• E.The overall system performance may degrade because of heavy hard disk use and memory reorganization.
