Passed the exam today. Advice to anyone going to the exam is to thoroughly go through all the recommended flashcards. I haven't done it so I had a lot of "surprise" questions. Everything went well in the end. Thank you guys from Linux Academy. Really helped a lot in Having a concise knowledge structure whilst preparing for the exam was crutial.
One surprise question was about STS service. What feature would you use given certain environment requirements. This one was the biggest surprise.
