CompTIA Linux+ XK0-006 (V8) Practice Question

The correct answer is that the network interface associated with the e1000e driver is active. The rmmod command is used to remove a kernel module, but it will fail if the module's usage count is greater than zero. An active network interface that relies on the e1000e driver will increment its usage count, thereby preventing its removal until the interface is taken down. Executing the command without root privileges would result in a 'Permission denied' error, not 'module in use'. The location of the module file is irrelevant for unloading an already loaded module. While a --force flag exists, it is dangerous and not the standard or correct way to handle this error; the proper procedure is to stop the processes or devices using the module.
