Easily cleared the doubts

As a person, i always have many doubts for one or the other thing. So when i opted to give NSE 7 certificate exam, my mind was full of tons of doubts for one subject or the other. But practicing on Fortinet NSE 7 mock tests helped me clear my doubts with practical assistance. System and session troubleshooting section was slightly difficult to understand earlier but eventually all my doubts were cleared.
