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
  4% (2)
• B
  2% (1)
• C
  2% (1)
• D
  92% (46)

Explanation

Defragmenting a drive reorganizes fragmented files so the read head can access them in fewer, more efficient movements - and defrag c: -w is the correct Windows command-line syntax to do this, where -w triggers a full defragmentation pass. This directly improves file access performance, making D the right answer.

Why the distractors fail:

• A & B are hardware upgrades, not maintenance tasks - the question specifically asks about maintenance. Swapping drive types doesn't maintain anything; it replaces hardware.
• C uses fdisk, which is a disk partitioning utility, not a defragmentation tool. Running it with -d -w on a Windows path like c:/ is also syntactically invalid and could be destructive.

Memory tip: The correct command literally spells out the action - defrag for defragmentation. If the command name doesn't match the task, it's almost certainly wrong. On exams, watch for trick answers that mix real tools (fdisk) with the wrong context.
