Hi ,

Its great to hear to want to pursue further.

Send me an email off line at my email and i will try and send you a ccda guide official stuff.
thatz pdf, so i can publish it somewere , will c the best i can do to help you.

Based on my experience , What i would do is to delve a bit more into the contents of the CCNA , and look up the ladder with CCNP, which would not only increase my knowledge
but at the same time , lay a ground , that would then enhace my ability to understand the design subject better.

You might also want to look at exposure to more technologies besides CCNA curriculum.
as CCDA covers different technolgies.

Did u know that after CCNP (Routing & switching papers) just 1 exam could make u CCDP. :-)
