Why not knock out two birds with one stone? You could enroll in a community college and get an associates degree in two years. The best thing is if you enroll in a Computer Sciences program you could also take classes and certify in CCNA. In fact several universities have CCNA as a part of their curriculum.
My take is this there are a lot of very talented professionals in the field, so to just get a certification will not always work out best but if you can combine work experience with certifications and throw in a degree for good measure then you are firing on all cylinders and your choices widen greatly.
