Question

To make changes permanent for kernel parameter files found under /proc/sys, the following file can have entries added to it:

a)/etc/procsys.conf
b)/etc/procctl.conf
c)/etc/sysinfo.conf
d)/etc/sysctl.conf *

Answer 1

/etc/sysctl.conf is the file where entries can be added to make changes permanent for kernel parameter files found under /proc/sys in Linux systems. The changes made in this file will persist across reboots.

Step-by-step explanation:

/etc/sysctl.conf is the correct file to add entries for making changes permanent for kernel parameter files found under /proc/sys. This file is used to configure kernel parameters in Linux systems. By adding entries to this file, you can modify various system settings and make them persist across reboots.

To add entries to /etc/sysctl.conf, you can use a text editor such as Nano or Vim:

• Open a terminal on your Linux system.
• Use the command sudo nano /etc/sysctl.conf to open the file in Nano (replace Nano with Vim if you prefer).
• Add your desired entries at the end of the file in the format parameter_name = value.
• Save the file and exit the text editor.
• To apply the changes, either reboot your system or use the command sudo sysctl -p to reload the configuration from /etc/sysctl.conf.
