All difficult topics now cleared

XtremIO X1 and X2 Installation, XtremIO X1 and X2 Solution Integration topic was so so tough for me that i was on the verge of quitting E20-368 certification exam. But thank god i came across this Dell EMC XtremIO Solutions Specialist for Implementation Engineer mock tests. These tests are very streamlined and it helped me clear all the doubts related to the topics in the syllabus which i did not understand and today when i came across my result of the recently given exam, i jumped with joy. I scored 89% in the exam and my very very happy.
