Question 5

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.

Answer : B

Question 6

In case the file containing the Linux kernel is lost, what happens when the system is booting?

BInstead of the kernel, the initramfs is loaded and instructed to mount the root filesystem and reinstall the kernel from the original package or from source.

CThe bootloader mounts the root filesystem read-only and launches /bin/sh directly in order to allow the administrator to reinstall the kernel.

DWithout a kernel a system cannot boot and, depending on the bootloader, an error is displayed.
