True

Question 3

Which of the following could cause slow performance of a hard drive?

Answer 3

File fragmentation
Disk thrashing
Insufficient amount of RAM

Question 4

Disk Defragmenter is a software tool used for rearranging data on disks and drives in order to improve system performance. Defragmentation results in faster read/write operations of the magnetic hard drive’s read/write heads as they can access the data sequentially without seeking data fragments in different areas of the disk (defragmentation consolidates data into smallest contiguous regions).

Answer 4

True

Question 5

What is the correct sequence of steps for launching the disk defragmenter utility in MS Windows?

Answer 5

Press the R key while holding the Windows Logo key -> type in “cmd” (without quotation marks), and hit Enter -> Launch the disk defragmenter utility by typing in DEFRAG with the appropriate command switch

In Windows 8/8.1: Open File Explorer by pressing the E key while holding the Windows Logo key -> Click on the This PC menu item list on the left to display all drives -> Right-click on the drive and select Properties from the pop-up window -> Launch the disk defragmenter utility available on the Tools tab

Question 6

Similarly to magnetic drives, Solid State-Drives (SSDs) require periodic defragmentation in order to improve system performance.

Question 14

One of the fixes for the “NTLDR is missing” error message during system boot relies on replacing the corrupt NTLDR file with the same file copied from another Windows host using the same operating system (Windows XP), or restoring it from the Windows XP installation CD. Copying the NTLDR file manually requires access to the command-line interface which can be found as one of the options available in the Advanced Boot Options menu displayed after pressing the F8 key during system boot. After gaining access to the CLI, the NTLDR file can be restored with the COPY command from an external storage device (e.g. USB flash drive) to the root folder (typically C:) of the drive containing the corrupt version of the file.
