Question 3
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 memoryreorganization.
- Since processes always exist completely in either RAM or swap, regular RAM may become unused if thekernel 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 canbe kept to a minimum by the regular use of memfrag -d.
- Applications need to restart because their virtual memory addresses change to reflect memory relocationto the swap address area.
Correct answer: B
