CCNA R&S
The course provides the foundational knowledge of network layers 1-3 that are applicable to core routing and switching and introduces advanced technologies. Topics include the interactions and network functions of firewalls, wireless controllers and access points, along with additional focus on IPv6 and basic network security.
The course provides the knowledge and skills needed to install, configure, operate, and troubleshoot a small enterprise network. Key topics include QoS elements, virtualized and cloud services, along with controller types and tools that are available to support software defined network architectures.
As Enterprises migrate toward controller based architectures, the role and skills required of a core network engineer are evolving and more vital than ever. To prepare for this network transition, the CCNA Routing and Switching certification will not only prepare you with the knowledge of foundational technologies, but ensure you stay relevant with skill sets needed for the adoption of next generation technologies.
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.
The content of the exams is proprietary. Cisco and its learning partners offer a variety of different training methods, including books published by Cisco Press, and online and classroom courses available under the title "Interconnecting Cisco Network Devices."
