SWITCHING AND ROUTING

The Cisco Certified Network Associate - Routing and Switching (CCNA - Routing and Switching) certification was developed by Cisco to test a candidate's knowledge of networking at entry level.  The Cisco Certified Network Associate - Routing and Switching (CCNA - Routing and Switching)  certification analyzes the candidate's ability to install, configure, operate, and troubleshoot medium-size  routed and switched networks.
