RHCSA RHCSA Software Package Management 3

Question 1

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

Accepted Answer

dnf install ./package.rpm

Answer

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

Question 2

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

Accepted Answer

dnf remove <package>

Answer

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

Question 3

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

Accepted Answer

The module stream is enabled

Answer

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

Question 4

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

Accepted Answer

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

Answer

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

Question 5

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

Accepted Answer

rpm --checksig <package.rpm>

Answer

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