As part of the requirements for installing a new application, the swappiness parameter needs to be changed to 0. This change needs to persist across reboots and be applied immediately. A Linux systems administrator is performing this change. Which of the following steps should the administrator complete to accomplish this task?
Correct Answer: A
To persist the parameter value indefinitely -- that is, until the user wants to change it again - they must manually update the sysctl.conf file. The command calls the nano text editor, which lets the user edit the file directly in the terminal. When the file opens, the user scrolls to the end of the text and adds the following setting. "vm.swappiness=0" >> append /etc/sysctl.conf && sysctl -p sysctl -p ( ( allows you to load the settings from a configuration file )
