CompTIA Linux+ XK0-006 (V8) Practice Question

A storage vendor certifies only the kernel that ships with your Red Hat Enterprise Linux 9 server. You must permanently prevent any future dnf operation from installing or upgrading packages whose names start with kernel, without relying on additional plug-ins or extra command-line options. Which change will accomplish this goal?

  • Run dnf versionlock add kernel* to lock the package and enable the versionlock plug-in.

  • Set enabled=0 for the [baseos] repository in /etc/yum.repos.d/redhat.repo.

  • Create /etc/apt/preferences.d/kernel containing:

    Package: kernel
Pin: release a=*
Pin-Priority: -1

  • Add the line excludepkgs=kernel* to the [main] section of /etc/dnf/dnf.conf.
