LPI Exam 201-450 Topic 7 Question 107 Discussion

Actual exam question for LPI's 201-450 exam

Question #: 107
Topic #: 7

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

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

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

CSince 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.

DThe 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.

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

Swap space? More like 'Swap Nightmare'! I'd rather have a system with infinite RAM than deal with the performance hit of constant swapping.

E) is just plain wrong. Applications don't need to restart just because their virtual memory addresses change. The kernel handles that transparently.

D) is just ridiculous. Who actually uses 'memfrag -d' to 'minimize' memory fragmentation? Clearly, the developers who wrote that option have never used a real system before.

I agree with Detra. Constant swapping between RAM and disk is bound to hurt performance. Although C) sounds plausible, I don't think that's the primary side effect.
