I want to sincerely thank Linux Academy for the guidance and training. I passed the exam today and scored 80%. I do not have direct exposure to AWS, except for the AWS free tier and Linux Academy training materials and the labs. However, I need to emphasis one point here, my past experience in technologies such as data centre, IT infrastructure, middleware, security and networking helped me a lot in understanding AWS.
So, as repeatedly mentioned by trainers, prerequisites such Linux and networking concepts is must.
On exam point of view, without Linux Academy, I would have not made it ..
