I am bad at these... past 6 questions in a row I got wrong.
I thought it was trusted platform module and as soon as I clicked on Submit, I realized it was wrong but it was too late to change it. I need to think more about these before clicking on submit.

The above is all just my opinion on what you should do.
As with all advice you find on a random internet forum - you shouldn't blindly follow it. Always test on a test server to see if there is negative side effects before making changes to live!
I recommend you NEVER run "random code" you found online on any system you care about UNLESS you understand and can verify the code OR you don't care if the code trashes your system.
