What Is the Cisco CCDE Certification?
The Cisco Certified Design Expert (CCDE) certification is Cisco’s expert-level credential focused on network infrastructure design, rather than configuration or implementation. It is vendor-neutral at the conceptual level but requires a deep understanding of Cisco’s design methodology.
Unlike certifications that focus on technical implementation, CCDE shifts the focus to design decisions, strategic planning, and business outcomes. It ensures that certified professionals can work on complex network design projects, communicate effectively with business stakeholders, and align technical decisions with business goals.
