My CCNA will be expiring this summer, and in addition to renewing or upgrading that, I'm considering trying for a linux related certification. I've come across a few googling, but I'm having a hard time trying to figure out which would be the most useful. So I guess my question is what would the "best" linux cert be, or would there be a better way to try to enter the linux career field?
I know redhat's cert is widely known, but I'd prefer not to box myself into a particular distro, but if I had to my choice would probably be debian. Any suggestions?
