A. device name; mount point; mount options; filesystem type; dump filesystem; fsck order"
B. device name; filesystem type; mount point; mount options; dump filesystem; fsck order
C. mount point; filesystem type; device name; mount options; dump filesystem; fsck order
D. mount point; device name; filesystem type; mount options; dump filesystem; fsck order
E. device name; mount point; filesystem type; mount options; dump filesystem; fsck order

Answer: E
Explanation:
The file fstab contains descriptive information about the various file systems, fstabisonly read by programs, and not written; it is the duty of the system administrator to properly create and maintain this file. Each filesystem is described on a separate line; fields on each line are separated by tabs or spaces. Lines starting with #are comments.

The order of records in fstab is important because sequentially iterate through fstab doing their thing. Pattern of /etc/fstab is:
device mount point filesystem mountoption dump fsck order
Example
/dev/hdal/boot ext3 defaults 11

QUESTION NO: 2
One of the IDE hard drives in a server is transferring data very slowly. What command must be run to enable DMA on it?

A. hdparm -d 1 /dev/hda
B. hdparm -dma /dev/hda
C. hdparm -d /dev/hda1

D. hdparm -d /dev/hda
E. hdparm -dma /dev/hda1

Answer: A
Explanation:
hdparm provides a command line interface to various hard disk ioctls supported by the stock Linux ATA/IDE device driver subsystem. Some options may work correctly only with the latest kernels.
-d Disable/enable the "using_dma" flag for this drive. This option now works with most combinations of drives and PCI interfaces which support DMA and which are known to the IDE driver. It is also a good idea to use the appropriate-X option in combination with-dl to ensure that the drive itself is programmed for the correct DMA mode, although most BIOSs should do this for you at boottime. Using DMA nearly always gives the best performance, with fast I/O throughput and low CPU usage. Butthere are at least a few configurations of chipsets and drives for which DMA does not make much of a difference, or may even slow things down (on really messed up hardware!). Your mileage may vary.
