Which three statements are true configuration files and the behavior of module parameters specified in those files, in the /etc/modprobe.d directory?
Correct Answer: A,C,D
Explanation/Reference:
Explanation:
modprobe.d - Configuration directory for modprobe
Because the modprobe command can add or remove more than one module, due to modules having dependencies, we need a method of specifying what options are to be used with those modules (A). All files underneath the /etc/modprobe.d directory which end with the .conf extension specify those options as required. They can also be used to create convenient aliases (D): alternate names for a module, or they can override the normal modprobe behavior altogether for those with special requirements (such as inserting more than one module).
C: options modulename option...
This command allows you to add options to the module modulename (which might be an alias) every time it is inserted into the kernel: whether directly (using modprobemodulename or because the module being inserted depends on this module.
