After working at a data center for a couple years I have finally made the move to a network provider that resells bandwidth on their Tier 1 circuits to corporations to make private network interconnect between their offices around the globe. I have been toying with the idea of getting my CCNA for a while and have finally decided to go for it. Anyone have suggestions for final preparation purchases such as practice exams or something else that will help with review? I am keenly aware that Cisco is not the end-all-be-all of networking but, considering my lack of experience in the job market I see this certification as a statement of a certain level of conceptual knowledge.
Additionally, has anyone found posters or "cheat sheets" for network protocols? I have looked for a TCP/IP & PPP poster to no avail.
Slightly off topic but,
Does that make us a Tier 1 provider? We buy dedicated pipes to connect all of our POPs so our customers traverse our network only when doing site-to-site communication.
