Definition: CCNA is a popular certification in computer networking developed
by Cisco Systems. Cisco created the CCNA to recognize basic competency in
installation and support of medium-sized networks.
The core CCNA certification can be obtained by passing a single 90-minute
written exam. The exam has no prerequisites, although Cisco and other
companies offer various formal training courses to help students prepare.
Topics covered on the CCNA exam include
LAN and WAN design (including the OSI model)
IP addressing
Routers and routing protocols (including OSPF, EIGRP and RIP)
VLAN (virtual LAN) and WLAN (wireless LAN)
Network security and management (including ACLs)
