Question

susan works in the research - and - development department. she recently purchased a large high - speed external drive and has attached the drive to her computer using a usb cable. the drive requires a minimum data transfer speed of 5 gbps and needs to access 600 ma (5 volts) of usb power to function properly. although the correct drivers are installed, when she plugs her drive into her workstation, the drive is not working. to troubleshoot the problem, she has connected her drive to her coworkers computer, where the drive functions properly. no additional software is required for this drive. which of the following is the most likely reason that susans external hard drive is not working? susan has connected her drive to a usb 1.1 port, but the drive is only made to work with a 2.0 port. susan has connected her drive to a usb 2.0 port, which does not have the required data transfer speed. susan has connected her drive using a type - c cable, which does not have enough power for her drive. susan has connected her drive to a usb 1.2 port, which does not support the minimum data transfer speed required.

Explanation:

Step1: Analyze requirements

The drive requires a minimum transfer speed of 5 Gbps and access to 600 mA (0.6 A) of USB - power from a host port.

Step2: Evaluate option A

USB 1.0/1.1 ports have very low data - transfer speeds (1.5 Mbps or 12 Mbps) and are not likely to meet the 5 Gbps requirement, but the question doesn't mention USB 1.0/1.1 specifically in options.

Step3: Evaluate option B

USB 2.0 ports have a maximum data - transfer speed of 480 Mbps (0.48 Gbps), which is less than the required 5 Gbps. So, if Susan connected her drive to a USB 2.0 port, it would not work due to insufficient data - transfer speed.

Step4: Evaluate option C

There is no information suggesting that a Type - C cable has power issues for this drive in the problem description. Also, Type - C can support high data - transfer speeds and sufficient power in many cases.

Step5: Evaluate option D

USB 3.2 supports high data - transfer speeds well above 5 Gbps and can provide sufficient power for many devices. So, it is not the likely cause of the problem.

Answer:

Susan has connected her drive to a USB 2.0 port, which does not have the required data transfer speed.
