I was a little off when the topics Alibaba Cloud Security services and CloudMonitor and General knowledge about Cloud Computing were concerned. The syllabus being vast, I could not understand many things at one point of time. But the online practice exams had a different way of making the topic understand. With different types of questions on the same topic, the topic automatically got covered by the way of mocks. Alibaba ACA Cloud Computing certification exam has been an exhilarating experience and I will always remember it as a pleasant one thanks to the practice exams with lots of opportunities to succeed.
