CISCO certification CISCO

CISCO offers certification in different domains -routing and switching, service provider, security and voice.

CCNA (Cisco Certified Network Associate)

The 640-802 CCNA is the composite exam associated with the Cisco Certified Network
Associate certification. Candidates can prepare for this exam by taking the Interconnecting
Cisco Networking Devices Part 1 (ICND1) v1.0
and the Interconnecting Cisco Networking
Devices Part 2 (ICND2) v1.0
courses. This exam tests a candidate's knowledge and skills required to
install, operate, and troubleshoot a small to medium size enterprise branch network. The topics
include connecting to a WAN; implementing network security; network types; network media; routing and switching fundamentals; the TCP/IP and OSI models; IP addressing; WAN technologies; operating and configuring IOS devices; extending switched networks with VLANs; determining IP routes; managing IP traffic with access lists; establishing point-to-point connections; and establishing Frame Relay connections.
