Which of the following commands will accomplish this task?

A Linux administrator has been tasked with installing the most recent versions of packages on a RPM-based OS.

E . yum check-update

Answer: D

Explanation:

The dnf update command will accomplish the task of installing the most recent versions of packages on a

RPM-based OS. This command will check for available updates from the enabled repositories and apply them to the system. The apt-get upgrade command is used to install updates on a Debian-based OS, not a RPM-based OS. The rpm -a command is invalid, as -a is not a valid option for rpm. The yum updateinfo command will display information about available updates, but it will not install them. The yum check-update command will check for available updates, but it will not install them.
