TS-C (NCCT) case studies
TS-C · Put your knowledge to work in context.
TS-C is an exam code for a technical systems certification aimed at practitioners who plan, deploy, operate, and support technology infrastructure in production environments. It is written for people with hands-on exposure to the technology rather than for pure theorists: engineers, administrators, implementation consultants, and support staff who are expected to make design decisions and then live with the operational consequences. The TS-C case studies are 5 cases and about 4,155 words.
