I've never done a ccna or similar cert, so its definitely not a requirement.

If the course covers setting up firewalls, vlans, subnets etc, then it will definitely be applicable. I have attempted to vlan/subnet some of the less trustworthy devices on my network, and it wasnt easy with my limited experience.
