CCNA certification belongs to the entry certification of Cisco after-sales engineer certification system. Through CCNA, you can prove that you have mastered the basic knowledge of network and can initially install, configure and operate Cisco routers, switches and simple local area networks and wide area networks. CCNA certification means that the certified personnel have the basic technology and related knowledge of the networked small office/court office (SOHO) market. Professionals certified by CCNA can install, configure and operate LAN, WAN and dial-up access services in small networks (nodes below 100 or 100). The protocols they can use include (but are not limited to) IP, IGRP, IPX, serial, Apple, Talk, frame, relay, IP RIP, VLAN RIP, Ethernet and access list.

CCNP certification (Cisco certified network professional) means that the certified personnel have rich network knowledge. Professionals with CCNP certification can install, configure and operate LAN, WAN and dial-up access services for large enterprise networks with more than 100 to 500 nodes.

CCNA (Cisco Certified Network Associate) is the most elementary certification in the whole cisco certified system, and it is also a necessary condition for obtaining CCNP certification, CCDP certification and CCSP certification (CCIP certification and CCIE certification are not mandatory), and many qualified Cisco colleges also require candidates to obtain CCNA certification first.
