Gentlemen, the CCNA is just the tip of a very high iceberg. This is practically an introduction to computer networks. Things at the academy are absolute basics. The real fun begins at the CCNP stage. The certificate is divided into 4 exams (routing, switching, security, optimization). The test exam itself is not difficult, but you have to put a lot of effort into it. As for the certificates themselves, the ones given at the beginning are a bit strange. As far as I know the cisco path, it looks like this:
Associate level: CCNA, CCDA
Profesional level: CCNP, CCDP, CCVP, CCSP
Expert level: CCIE (R&S, Security, VoIP, Storage)
In addition to this, there is a special path for sellers (CQS).
Another issue is the respect of certificates by employers. It is different with this. If the company is real, there is no problem with respecting the certificates and getting a job (at least CCNP). If a potential employer does not know what these certificates are, it is not worth bothering about them. Well, unless someone likes to play with D-Link or similar SOHO equipment.
Overall, cisco hardware is practically the backbone of wide area networks. There is practically no alternative but Juniper. Some people play Alcatel, AlliedTelesyn, 3Com, but this equipment is only used in specific applications. Alcatel is mainly ISDN and toys related to analog telephony. AlliedTelesyn is a cheap Hong Kong crap. Not worth your interest. 3Com rather plays with equipment for end users (network cards, managed switches).
Coming back to the topic of the Cisco academy. While it makes sense with CCNA, it makes little sense with CCNP. As for the expert level, bootcamps in the US are rather preferred.
