Which of the following commands identifies dependency information for all modules and displays the results on the screen without creating a file with the dependency information?depmod -anYou've just purchased a new input device named GamePad that you want to use on your computer. You don't think that the GamePad driver (the kernel module) was compiled into the kernel of your Linux distribution. Which of the following commands will install the driver (gamepad.ko) into the kernel? (Select two.)1. modprobe gamepad 2. insmod gamepad.koWhich command displays information about all loaded modules on the system?lsmodThe modprobe.conf file provides the modprobe utility with default commands for loading modules at boot time. What is the entry you can use in the file to load a module at boot time?installWhich utility runs at startup to load modules into the kernel?modprobeWhat file is used to provide configuration settings for the modprobe utility when the modprobe.conf file does not exist?modprobe.dWhich of the following commands will check for dependencies before loading the gameport module in the kernel?modprobe gameportWhich of the following commands will check for dependencies before removing the debug module from the kernel?modprobe -r debugWhich of the following are important to remember when using the rmmod command to remove a module from the kernel? (Select two.)1. Cannot unload the module if it is in use. 2. Does not look for dependencies.Which of the following describes the difference between the /lib/modules directory and the /usr/lib/modules directory? (Select two.)1. Both directories contain hard links to the kernel modules. 2. /lib/modules is available to root in single-user mode, while /usr/lib/modules is available to all users.Which of the following device categories do RAM chips, CPUs, expansion cards (such as PCI cards), and standard hard disk drives belong to?Coldplug devicesWhich of the following daemons allow processes to communicate with each other and relay information about hotplug devices?D-BusWhich of the following daemons provides all applications with data about the current hardware?haldWhich of the following devices is a hotplug device?USB flash driveMatch the term on the left with the correct definition on the right.D-Bus: Allows processes to communicate with each other and notify one another of new hotplug devices. hald: Provides all applications with data about current hardware. udev: Dynamically creates device files in a virtual file system as devices are added and removed. sysfs: Exports information about hotplug devices so that other utilities can access the information.What is the full path to the directory that allows you to name devices when they are connected to the system?/etc/udev/rules.d/Which of the following exports information about hotplug devices so that other utilities can access the information?sysfsWhich of the following commands is designed to give you the ability to control the udev daemon?udevadm controlWhich of the following commands would you enter to add the pci subsystem to your Linux server? (Select from the drop-down list.)udevadm trigger --action=add --subsystem-match=pciWhen a hotplug device is added or removed, the kernel sends out a uevent message that is picked up by the udev daemon (udevd). Based on the rules defined in the files in the /etc/udev/rules.d directory, what does udevd do next after udevd initiates the device?Creates the appropriate device file in the /dev directory.
