I used ACG as my primary lecture source and started learning about a month ago, creating flashcards as I went for spaced repetition. (https://ankiweb.net/shared/info/1471728029). In the final 2 weeks I used Wizzlabs to test my knowledge. IMO the ACG practice exam whilst useful is geared more towards testing your knowledge of what ACG has covered rather than an accurate representation of the actual exam questions. Wizzlabs was better but again wasn’t 100% accurate. There were a lot of "you have x setup and y isn’t working. What 3 things do you need to do in order to fix it?". There were very few ‘which service is most appropriate’ and almost no single-service answers.
Without question, you need to know the use-cases and limitations for each service, as well as some configuration options.
I hope this helps someone. In the end, it’s not all that difficult and if you’ve done the CCP exam, I’m sure they’ve used some of the same questions. I’ll be around the thread to answer questions if needs be.
I believe in you, you can do it.
