CompTIA Linux+ (XK0-005) — Question 53

A systems administrator made some unapproved changes prior to leaving the company. The newly hired administrator has been tasked with revealing the system to a compliant state. Which of the following commands will list and remove the correspondent packages?

Answer options

• A. dnf list and dnf remove last
• B. dnf remove and dnf check
• C. dnf info and dnf upgrade
• D. dnf history and dnf history undo last

Correct answer: D

Explanation

The correct answer is D because the 'dnf history' command provides a record of all package transactions, and 'dnf history undo last' can revert the most recent changes. Options A, B, and C do not effectively target the removal of last changes made, as they either list or check packages without the ability to undo recent modifications.
