Description: Candidates should be able to manage and/or query a 2.6.x, 3.x or 4.x kernel and its loadable modules. Candidates should be able to identify and correct comm-on boot and run time issues. Candidates should understand device detection and management using udev. This objective includes troubleshooting udev rules.

Use command-line utilities to get information about the currently running kernel and kernel modules
Manually load and unload kernel modules
Determine when modules can be unloaded
Determine what parameters a module accepts
Configure the system to load modules by names other than their file name.
