CompTIA Linux+ (XK0-005) — Question 81

A systems administrator is tasked with installing GRUB on the legacy MBR of the SATA hard drive. Which of the following commands will help the administrator accomplish this task?

Answer options

• A. grub-install /dev/hda
• B. grub-install /dev/sda
• C. grub-install /dev/sr0
• D. grub-install /dev/hd0,0

Correct answer: B

Explanation

The correct command is 'grub-install /dev/sda' because '/dev/sda' refers to the primary SATA hard drive in a typical setup. The other options are incorrect as '/dev/hda' refers to older IDE drives, '/dev/sr0' is for optical drives, and '/dev/hd0,0' is an invalid syntax for specifying a hard drive in this context.
