CCNA Introduction

The Cisco Certified Network Associate - Routing and Switching (CCNA - Routing and Switching ) certification title has become the leading entry level network certification available today. 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.

The CCNA - Routing and Switching certification is recognized by IT employers when considering a fresher's profile for a vacancy or for a salary hike/promotion for experienced employees. The Cisco Certified Network Associate - Routing and Switching (CCNA - Routing and Switching) exam covers a broad range of networking concepts to prepare candidates for the technologies they are likely to work with in today’s network environments.

New version of CCNA Exam (Exam Number 200-120 CCNA Routing and Switching) is available from March 26, 2013. The last date for CCNA examination according to the old version (Exam Number 640-802 CCNA) is September 30, 2013. After September 30, 2013, only 200-120 CCNA Routing and Switching will be available. Please visit Cisco official CCNA Routing and Switching web page for more information.

CCNA exam syllabus includes TCP/IP, IP Addressing and Subnetting, Routing Information Protocol (RIP), Routing Information Protocol V2 (RIPv2), IGRP (Interior Gateway Routing Protocol), Enhanced Interior Gateway Routing Protocol (EIGRP), Open Shortest Path First (OSPF), Serial Line Interface Protocol, Frame Relay, VLANs, Ethernet, access control lists (ACLs) etc.

Thorough knowledge in Basic Networking and TCP/IP is required to continue CCNA Routing and Switching learning. If you are new to networking, we request you to click the following links to learn Basic Networking and TCP/IP.
