The Cisco Certified Internetwork Expert (CCIE) is the highest level of professional certification that Cisco provides. CCIE was the first Cisco Certified qualification, and as such there were no other certifications that could be taken prior. The development of the associate and professional certifications was due to recognition of the fact that a CCIE is over kill for many networking personnel, and also for the vast majority of businesses who employ such people, and that certifications needed to be offered at lower levels. Despite the development of the lower certifications, Cisco has chosen not to make them formal requirements for the CCIE certification.



The CCIE what CISCO describes as its “premium networking certification" is widely regarded as having one of the toughest, most demanding exams. It includes both a written exam and a day-long lab exam. This certification is aimed at senior level networking professionals who design, build, implement, maintain, or troubleshoot complex enterprise networking infrastructures. CCIE recipients can specialize in routing and switching, communications and services, security, or voice systems and technologies.
