My experience was very good

I had difficulty in the Concepts and OneFS Storage Efficiency and Services topics while preparing for the DEE-1421 certificate exam. The Dell EMC PowerScale Solutions Expert exam syllabus was quite huge and i did not know what to do. However, online mock tests on edusum.com really really helped me get through the topics in an organized fashion. I scored 90% and am really proud of my first attempt score.
