It's a bit of an odd one. Most people say the CCDA is harder and I'd agree, but not necessarily for the right reasons. I think my general opinion is that the exam itself is, putting it harshly, junk. The course however is very good. It's basically part of my day job anyway and a lot of it was essentially second nature, however there's also some material that really makes you think and provides useful training and information on improving your design skills and understanding the
what and
why. Hopefully when they convert it from a 642 to a 300 exam it gets improved.
So yes, worth doing, but the exam isn't that good in itself - more of a means to an end. I wouldn't recommend anybody rushing to it over your CCNP and a few other base certs. I just picked it as it was one exam to complete the CCDP track and recertify everything (had 30 days before everything expired, no pressure! been busy with other vendors
)
