I am Minh, and this is my personal note while preparing for AWS exam.
Thank for great support from the AWS Community,
I have gained a lot of interesting base knowledge
and just passed SA Associate exam with score 89% (and is in preparing for Pro :).
Besides studying AWS concepts via their best practices (what is really valuable),
spending certain time on questions contributed by the community was also very useful for the exam.
Unfortunately, there is no 100% correct answer for all of available questions.
You need to research, consider comments contributed by cool guys in the community as references, and make your own final answers.
So do I - collecting my own list during exam preparation time.
After passed the exam, I wanna share own answers here as a small reference
for someone who is preparing for the exam like me before.
Feel free to leave a comment. I will check and do some help whenever available.
Hope it could help you somehow :)
