RHCSA Software Package Management Flashcards

You need to install a local RPM file that has dependencies in configured repositories. Which command handles this automatically?

Answer: dnf install ./package.rpm

'dnf install ./package.rpm' installs a local RPM and resolves dependencies from configured repositories; rpm -ivh does not resolve repo dependencies.

Which command removes a package AND all packages that depend on it?

Answer: dnf remove

'dnf remove' automatically removes the package and any packages that would be broken without it.

What does 'dnf module list' output's 'e' status indicator mean?

Answer: The module stream is enabled

In 'dnf module list' output, 'e' in the Status column means the stream is enabled (active/selected), while 'd' means disabled.

A system needs to have kernel updates excluded permanently. Which file and directive would you use?

Answer: Add 'exclude=kernel*' to /etc/dnf/dnf.conf

Adding 'exclude=kernel*' to the [main] section of /etc/dnf/dnf.conf permanently excludes kernel packages from all DNF operations.

Which rpm command verifies that a package's GPG signature is valid before trusting it?

Answer: rpm --checksig

'rpm --checksig' (or '-K') checks the GPG signature and digest of an RPM file to confirm it is authentic.

After adding a new repo file to /etc/yum.repos.d/, what command rebuilds the DNF metadata cache?

Answer: dnf makecache

'dnf makecache' downloads and caches metadata for all enabled repositories, making future operations faster.

What is the minimum set of fields required in a valid .repo file for DNF to use a repository?

Answer: [repoid], name=, baseurl= (or mirrorlist=), enabled=

A valid repo file needs a section ID, a name, and either baseurl or mirrorlist to locate packages; enabled defaults to 1 but is best practice to include.
