Last week I've finished the CCDA FLG book for the DESGN exam. The last chapter discussed wireless design and architecture at a very high level. There were tons of things I picked up from this chapter that helped me understand my employers wireless environment immediately. Mainly the Mobility and RF Group sections. We have a wireless refresh project coming up shortly (with the help of a vendor) and this will help me immensely.
Now I'm hitting the DESGN Official Certification Guide book along with taking copious amount of notes, making flash cards, and hitting the multiple choice questions hard. I'm not exactly sure when I'll take this exam this year but it should be before the end of summer. As mentioned before, I'm not exactly in a rush right now coming off fresh from the CCNP about four months ago.
After the CCDA, next up is CCDP, and then maybe...just maybe a CCIE level certification. Experience trumps all though so after the CCDP I may wait until my knowledge is and skill set is at a point where a CCIE certification makes sense. SDN and programmable networks are very intriguing to me but my gut keeps telling me that I need a really strong foundation before diving in to that.
