The best feature about the DEVOPSP certification exam preparation through the method of DevOps Foundation practice tests online was that I did not have to follow a routine. I was on my own and could tailor the number of hours of practice I can do in a day and at a time which was the best convenient for me. This helped me relax a lot. Further, the test schedule is decided by me. It is quite flexible so my performance too was better as there was no kind of stress involved while attempting the mock. I even got to see the result of my attempt and I could compare that with my earlier result with ease.
