You can see CCDE Written Exam ( 352-001 ) blueprint below.

For those who want to start their CCDE journey , probably knowing the topics is the first step.

orhanergun.net is the most comprehensive website on the internet for the Cisco Certified Design Expert ( CCDE ) exam. If you can’t find specific topic in the website, please share in the comment.

Also note that I worked with Cisco to reorganize CCDE Written recommended resources. You can reach it from here.
