Network/System Admin Profile.

chmod

I have seen several topics regarding what is the most recommended profile to get a job into IT world.(preferable as administrator)
For me, to be able to support everything, the most appropiate candidate must possess:

A+
Courses of linux and/or linux certifications.
MCSA or equivalent expirience
CCNA
Network+

if you really want to be an elegible candidate for an administrator position you must possess the above certifications. Plus experience.

This is only to comment what are the basic requirements to look for an admin job.
If you want to get far, focus in any specialization.
