CompTIA Linux+ (XK0-005) — Question 282

A Linux administrator is working on a system and notices that some of the packages are not at the latest version. Which of the following commands should the administrator use to correct this issue?

Answer options

• A. rpm --update
• B. apt update
• C. dnf update
• D. dpkg --update

Correct answer: C

Explanation

The correct command is 'dnf update', which is used in Fedora and other Red Hat-based distributions to update packages to their latest versions. The other options either do not update packages or are not appropriate for the distribution in question; for example, 'rpm --update' is not a valid command for updating packages.
