Top Down or cert guide first?

in CCDA & CCDP
Hey guys, I am awaiting a job offer that is going to require me to get some design knowledge. I know I want to read both Top Down Network Design and the CCDA cert guide, but which order should I do it in? From what I have been reading it seems like Top Down is a little more higher level but not as technical so it may be a decent starting point from what I can tell. Any input?

The CCDA is a tough exam to get through due to a variety of reasons, mainly dry/poor exam guide, poorly worded exam questions, random sales pitches and so forth. However, stick with it because the CCDP Arch is a good one.
If you are just looking to get some general network design knowledge then Top Down is a great resource and a must read for any network designer. The CCDP ARCH exam book is also a good one. I would recommended the arch book over the CCDA guide.
The cisco design zone also has some great design papers for each technology:

No not necessarily, i mean use the CCDP arch guide for those areas which overlap between the two certs. The Arch book contains better detail in those areas imo, However, much of the arch book is overkill and out of scope for the ccda exam
