Linux Foundation Certified System Administrator (LFCS) — Question 29

Which of the following commands lists all currently installed packages when using RPM package management?

Answer options

• A. yum --query --all
• B. yum --list --installed
• C. rpm --query --all
• D. rpm --list –installed

Correct answer: C

Explanation

The correct command is 'rpm --query --all', which specifically queries the RPM database for all installed packages. The other options either use the yum package manager, which is not applicable for listing RPM packages directly, or contain incorrect syntax that would not execute properly.
