Hello all. New user here. Bit about myself, am in my mid 20's, bachelor degree in IT with network security concentration and a minor in industrial tech. Looking to get a full time job and looking at some of the job descriptions there are specific knowledge needed in either software or hardware. For example active directory and Citrix and such, my question is that is there a way I can find a simulator or some kind of virtual Labs of those software to learn from because some of the things they ask for they don't teach in univ and at times I feel in just wasted four years learning already outdated skills and I have no plan to spend time digging my self more into the student debt. So all in all I just want to know if there are virtual Labs or so that I can learn from to at least get a basic understanding some of the company systems that are in use. Preferably free but I Will take what I can get as long as it helps me increase my competitiveness in the job market. Thanks.
