CompTIA Linux+ (XK0-004) — Question 224

After connecting a USB drive, the system is unable to detect it. There is no entry in /dev, and there is no information in the message log.
Which of the following is the issue?

Answer options

• A. The USB drive is formatted as a DVD
• B. The USB drive is not formatted
• C. The kernel module is not installed
• D. The permissions of /dev/usb are incorrect

Correct answer: B

Explanation

The correct answer is B because if the USB drive is not formatted, the system will not be able to recognize it or create an entry in /dev. Option A is incorrect since a USB drive cannot be formatted as a DVD; C is wrong because the kernel module would typically handle various USB devices regardless of formatting; D is not applicable here as permission issues would still allow detection of the device if it were formatted.
