CCNAX Ver. 2.0

It is an information technology (IT) certification from Cisco. CCNA certification is an associate-level Cisco Career certification. The Cisco exams have changed several times. In 2013, Cisco announced an update to its certification program that "aligns certification and training curricula with evolving industry job roles." There are now several different types of Cisco-Certified Network Associate, with "CCNA Routing and Switching" being closest to the original CCNA focus; other types of CCNA focus on security, cloud, collaboration, security operations, design, data center technologies, industrial plants, service providers, and wireless.


There are no prerequisites to take the CCNA Routing & Switching certification exam. However CCENT certification is recommended.


The validity for CCNA Certification is 3 years. Renewal requires certification holders to register for and pass the appropriate Cisco recertification exam(s) again every 3 years.
