Sorry Everyone, this is a very nooby question. I was looking at the official CompTIA Sec+ site, and it said SY0-401, but also had exam codes SY0-301 and JK0-018.
Security certification, CompTIA Security+ certification
It says that the latter ones are "retiring". What is the disadvantage of that? And also, what is the advantage if I take the newer one?
Thanks !!!
