A systems administrator needs to install a new piece of hardware that requires a new driver.
The driver should be manually installed.
Which of the following describes the order of commands required to obtain module information, install the module, and check the log for any errors during module installation?
Click on the arrows to vote for the correct answer
A. B. C. D.A.
The correct answer is C. modinfo, insmod, dmesg.
Here is a detailed explanation of the commands and their order:
modinfo - This command is used to obtain information about a kernel module. The module is the software component that is used to interact with the hardware. Running this command will provide the administrator with the necessary information about the module, such as the module name, version, and parameters. This command is used first in order to know which driver should be installed.
insmod - This command is used to manually install a kernel module. The module that was obtained with the previous command should be installed with this command. The command requires the name of the module as an argument. If there are any dependencies required for the module, they need to be resolved before running this command.
dmesg - This command is used to view the kernel log. This log contains information about system events, including module loading and errors. Running this command after the previous command will allow the administrator to view any errors that occurred during the installation of the module. This can be used to troubleshoot any problems that may have occurred during the installation process.
The other answer choices are incorrect because they either include the wrong commands or the commands are in the wrong order. Here is a brief explanation of why the other answer choices are incorrect:
A. lsmod, modprobe, modinfo - This answer is incorrect because the lsmod command is used to list the currently loaded modules, not obtain information about a specific module. The modprobe command is used to add or remove modules from the kernel, but it is not necessary in this scenario. The modinfo command should be used first to obtain information about the module.
B. modinfo, insmod, modprobe - This answer is incorrect because the modprobe command is not necessary in this scenario. The insmod command should be used to install the module after obtaining information with the modinfo command. The modprobe command is typically used to automatically load modules at boot time.
D. lsmod, insmod, dmesg - This answer is incorrect because the lsmod command is used to list the currently loaded modules, not obtain information about a specific module. The modinfo command should be used first to obtain information about the module.
