The correct answer is D. The front USB is not connected to the motherboard. If a USB device works when connected to the back of a server but not the front, the most likely cause is that the front USB ports are physically disconnected from the motherboard.

Question

An administrator attempts to boot a server off a floppy using an external USB 2.0 floppy drive. When the floppy drive was connected to the front panel of the tower server the system did not recognize the floppy drive. When the drive was connected to the back of the server the floppy was recognized. Which of the following is the MOST likely cause of the problem?

Options

  • AThe front USB is only compatible with USB 1.1 devices.
  • BThe front USB does not support floppy drives only hard drives.
  • CThe front USB is only compatible with USB 1.0 devices.
  • DThe front USB is not connected to the motherboard.

Why each option

If a USB device works when connected to the back of a server but not the front, the most likely cause is that the front USB ports are physically disconnected from the motherboard.

AThe front USB is only compatible with USB 1.1 devices.

USB 2.0 devices are generally backward compatible with USB 1.1 hosts, and a compatibility issue is less likely than a physical disconnection given the device works elsewhere.

BThe front USB does not support floppy drives only hard drives.

USB ports are generally universal for various USB devices, and there is no inherent limitation preventing front ports from supporting floppy drives while supporting hard drives.

CThe front USB is only compatible with USB 1.0 devices.

USB 2.0 devices are backward compatible with USB 1.0 hosts, and this is less likely than a physical disconnection given that the drive functions when connected to the rear ports.

DThe front USB is not connected to the motherboard.Correct

Front panel USB ports on a server tower connect to the motherboard via internal cables. If these cables are not properly connected or have become loose, the front USB ports will not receive power or data signals from the motherboard, rendering them non-functional, even though the physical ports are present on the case.
