Found out last week that I was going to get to Cisco Live, which includes a complementary cert exam. With 4 days to prep, I decided to go for the CCDP exam. I've speed read the ARCH Foundation Learning book to go with my CCIE lab prep knowledge.
Wish me luck everyone! If I pass, I'll follow up by taking the CCDA exam to actually get the title and become a triple Professional cert holder.
EDIT: I passed with a 945! Super excited. Now I get to focus on my CCIE lab exam to earn two new titles
