Exam XK0-004 topic 1 question 38 discussion

A is the correct answer. by booting into single usermode or rescue mode, you can change root passwd and user passwd by using the passwd command. exec /sbin/init to reboot

Correct Answer: A. Boot into single-user mode and reset the password via the passwd command. Summary of below link. 1. Boot to single user mode. 2. remote drive. 3. change password using passwd. 4. restart https://phoenixnap.com/kb/how-to-change-root-password-linux

this is a tough one because frankly none of them would really work. You have to boot into what is called "shell mode", a lesser mode than even single user. So we are left with the least worst answer which I believe is A: A will work, and answers the question better than... C which would also work, but this blanks the password, not creates a new one B is out because passwords are not in the /etc/passwd file. D is out because chage just changes password aging (expiration dates for when to make a new password)
