Concept clearance is very easy

In training courses, there is an exclusive doubt solving sessions in the end. By the time that session begins, the doubts are all forgotten and this is a scary thing. However, with C1000-153 mock tests, the doubts are solved as and when they arise through the medium of practice. I had a bag full of doubts regarding Configuration and Maintain the Environment topics. However, they eventually cleared and i am much more informed about this part of the syllabus now.
