The following: CCDE; CCIE Data Center; CCIE Collaboration; CCIE Service Provider; CCIE Security; CCIE Enterprise Infrastructure; CCIE Enterprise Wireless. Cisco Certified Design Expert (CCDE) is ideal for the expert-level network design engineers. It helps them develop design solutions at the infrastructure level for the large customer networks. Cisco 352-001 is the written exam that you have to pass before going for the 8-hour lab test. Another path has the same qualifying exams that are included in the Cisco Dumps professional-level certifications. The only difference is that there is a lab test for each of the paths instead of the list of concentration exams for choosing. Preparation Options Considering the fact that the CCDE certification has only one level of coverage with a broad range of topics, Cisco offers you a spreadsheet with all the links to the materials that you will need to explore for each of the topics. You can download the Excel file right on the certification webpage to get access to the resources.
