XK0-006 Practice Question: Verify which RPM packages are installed on a Red…
An administrator wants to verify which RPM packages are installed on a Red Hat Enterprise Linux system. Which command displays that information?
⚠ Common exam trap
The trap here is that candidates familiar with Debian-based systems might choose `dpkg -l` or `apt list --installed`, while those who use yum daily might pick `yum list installed` because it works, but the exam specifically tests knowledge of the native RPM command `rpm -qa` for direct package database queries.
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
✓
rpm -qa
The `rpm -qa` command queries the RPM database and lists all installed packages on a Red Hat Enterprise Linux system. The `-q` flag enables query mode, and `-a` specifies all packages, making it the correct tool for this task.
