Preparation for 6 Linux and cloud certifications, built the way the exams are actually sat: on live virtual machines, typing real commands, with the work checked on the machine itself rather than by multiple choice.
A subscription covers preparation: browser VM labs, mock exams, and walkthroughs. You book and pay for the official exam with the vendor directly. We do not sell vouchers and we do not guarantee a pass.
