NEW QUESTION 69
Which of the following is a side effect of extensive usage of swap space?

The root filesystem may become full because swap space is always located on the system root partition.

The overall system performance may degrade because of heavy hard disk use and memory reorganization.

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.

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.

Applications need to restart because their virtual memory addresses change to reflect memory relocation to the swap address area.
