It all depends on what area you are working in. I first started working on the help desk, so, of course, I needed A+. Now I am in the server room and I am working on my Server+ then my MCITP. But, there was a little catch in there, I also work for the DOD, and they mandated that to work in the IT field, you needed you have, at a minimum A+, Security+, and one in the field you work in. So I had to put Server+ on the back burner and get Security+ before the due date that they set. Now that I have that, I will be taking my Server+ next month. Since then, I have been assigned new taskers, so, I need to look at the path of which certs to get next. I am going to SAN boot Camp in August, so, I should walk out of there with a couple, but then I will also be working on SSCP because of the security portion that I work on here.
So, as the job changes, so do the paths.
