LPIC-1 Linux Installation and Package Management Practice Question
A Linux administrator is preparing a new server and needs to install a package group called 'Development Tools' on a CentOS 8 system. The administrator wants to see which packages are included in this group before installing. Which command should be used?
⚠ Common exam trap
Many exam-takers confuse commands that list all groups or install groups with the command that shows the specific packages within a group.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
dnf group info "Development Tools"
dnf group info provides a detailed breakdown of a package group, listing the packages that are part of it. This allows the administrator to review the contents before deciding to install. It is the standard way to inspect groups on CentOS 8 and other dnf-based distributions.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
dnf group info "Development Tools"
Why this is correct
dnf group info displays detailed information about a package group, including the list of mandatory, default, and optional packages. This allows the administrator to see exactly what will be installed. It is the correct command for inspecting a group's contents on CentOS 8.
- ✗
yum groupinstall "Development Tools"
Why it's wrong here
yum groupinstall installs the group and its packages, but it does not provide a preview of the packages. It would immediately begin installation, which is not what the administrator wants. Additionally, yum is deprecated in CentOS 8 in favor of dnf, though it may still work via symlink.
- ✗
dnf list groups
Why it's wrong here
dnf list groups lists all available package groups along with their group IDs and whether they are installed. It does not show the individual packages contained within a specific group, so it does not satisfy the requirement to see the group's contents.
- ✗
rpm -q --group "Development Tools"
Why it's wrong here
rpm -q --group queries installed packages that belong to a specific group. It does not list the packages that would be installed from a repository group, and it only works on installed packages. It is not suitable for previewing a group before installation.
