When you do it for work, you log what you have changed each time you make a change to try to fix it, and you log what you revert, so you can keep track of what you have tried, what worked, and what didn’t and have a clearer idea of what the solution was.

Sometimes it really does take a while to nail down though, and sometimes it isn’t entirely clear why what worked worked. Especially if you’re a junior network engineer without as much experience.
