Professionals who have an advanced knowledge of networking design concepts and principles often attempt to gain the CCDP (Cisco Certified Design Professional) certification. This is an intermediate level Cisco certification that acknowledges a professional's ability to discuss, design, and create addressing and routing. Additionally, the certification acknowledges a candidate's proficiency in security and network management.
Knowledge of virtual private networks and wireless domains are areas in which the CCDP excels. Through their daily tasks, a CCDP professional will be required to design network service architecture and build multilayer switched networks.
In order to gain the CCDP (Cisco Certified Design Professional) certification, a candidate must first obtain a CCDA and CCNA certification. Alternately, they can obtain a CCIE certification. After these prerequisites have been met, candidates must pass each of the following exams: 642-902 Implementing Cisco IP Routing (ROUTE), 642-813 Implementing Cisco IP Switched Networks (SWITCH), and Designing Cisco Network Architectures (ARCH).
Every CCDP certification remains valid for three years. If a candidate wishes to renew their CCDP certification, they can do so through passing any professional level exam, including 642-902 and 642-813. Alternately, candidates can renew their certification by passing any CCIE or CCDE Written Exam or CCDE Practical Exam. Additionally, professionals can renew their CCDP certification by passing the Cisco Certified Architect interview and board review to extend lower certifications.
