After passing the first exam required to get a CCNA DC certification: DCICN (640-911), obviously, I was also studying for the second exam: DCICT (640-916). As this exam brought less surprise to me in terms of exam content, it was still a lot of information to process and study. Especially since I got a lot of info from different sources and to help me with studying, I decided to do the same thing as with the first exam. You can find the information which I gathered to pass the exam in this post. Hope it helps.
