Which option to the yum command will update the entire system? (Specify ONLY the option name without any additional parameters.)

Explanations

update -or- upgrade

The yum command is used on many Linux distributions to manage software packages. To update the entire system, you can use the yum update command. This command updates all installed packages to the latest version available in the configured software repositories.

To specify the option name without any additional parameters, you can use the following command:

sql
yum update -y

The -y option automatically answers "yes" to any prompts that may appear during the update process, making the update process fully automatic. This option is useful when updating a large number of packages.

It is important to note that updating the entire system can sometimes result in unexpected changes or conflicts. Before running this command, it is recommended to review the list of packages that will be updated to ensure that it will not cause any issues with the system. Additionally, it is a good practice to back up important data before performing any system updates.
