The Cisco Certified Internetwork Expert, or CCIE, is a technical certification offered by Cisco Systems.
The Cisco Certified Internetwork Expert (CCIE) and Cisco Certified Design Expert (CCDE) certifications were established to assist the industry in distinguishing the top echelon of internetworking experts worldwide and to assess expert-level infrastructure network design skills worldwide. Holders of these certifications are generally acknowledged as having an advanced level of knowledge. The CCIE and CCDE communities have established a reputation for leading the networking industry in deep technical networking knowledge and are deployed in the most technically challenging network assignments. The expert-level certification program continually updates and revises its testing tools and methodologies to ensure and maintain program quality, relevance and value. Through a rigorous written exam and a performance-based lab exam, these expert-level certification programs set the standard for internetworking expertise.[1]
The program is currently divided into six different areas of expertise or "tracks". One may choose to pursue multiple CCIE tracks in several different categories of Cisco technology: Routing & Switching, Service Provider, Security, Collaboration, Data Center, and Wireless.
