Which of the following computer system maintenance tasks can help improve file access performance?

Question

Options

• AUse a SCSI drive instead of a SATA drive
• BUse a SATA drive instead of an EIDE drive
• CDefragment the drive using the following command: fdisk -d -w c:/
• DDefragment the drive using the following command: defrag c: -w

• A
  5% (3)
• B
  2% (1)
• C
  2% (1)
• D
  91% (51)

Explanation

Defragmenting with defrag c: -w is correct because it uses the actual Windows defragmentation utility, which consolidates fragmented files on disk so the read heads travel shorter distances to access them - directly improving file access performance. The -w flag forces a full defragmentation rather than a partial one.

Why the distractors fail:

• A & B describe hardware upgrades (swapping drive interfaces), not maintenance tasks - and regardless, hardware swaps don't qualify as "system maintenance."
• C is dangerous nonsense: fdisk is a partition management tool, not a defrag utility. Running fdisk -d would attempt to delete a partition, not defragment anything.

Memory tip: The correct command name literally spells out the task - defrag for defragment. If the command name doesn't match the job (like fdisk for defragging), it's wrong.
