Question 2

A DNF module stream is enabled but you want to switch to a different stream. What must you do first?

Accepted Answer

dnf module reset <module>

Question 3

Which file would you examine to see the history of all DNF transactions on a system?

Accepted Answer

/var/log/dnf.log

/var/log/dnf.log records all DNF transactions; the history database is in /var/lib/dnf/ but the human-readable log is /var/log/dnf.log.

Question 4

How do you list only the packages that are available as updates but NOT install them?

Accepted Answer

dnf check-update

Answer

'dnf check-update' lists packages with available updates without installing them; it exits with code 100 if updates exist.

Question 5

An administrator runs 'rpm -V httpd' and sees 'S.5....T. /etc/httpd/conf/httpd.conf'. What does the '5' indicate?

Accepted Answer

MD5 checksum differs from the package

Answer

In rpm -V output, '5' means the MD5 checksum (digest) of the file differs from what the package recorded at install time.
