I am currently studying for the CCSP, I have taken 3/5 exams and have CSIDS and SAFE to complete. I am working on the CSIDS and would like to be able to work with the command line. I would like to purchase or rent a unit for little money (if that's possible). I would hate to go into the exam without having actual hands-on experience. Has anyone had this problem and know where I may find a solution?
