And to maintain and manage enterprise computer network one must have profound understanding about network devices. There are numerous network vendors available in the market but most companies prefer to adopt Cisco based networks as Cisco is the pioneer in networking industry and is providing reliable network solutions at enterprise level. Now to maintain and manage computer network one must have knowledge about Cisco devices, that Cisco is offering various certifications regarding their technology among which CCNA is one of the most popular one. CCNA refers to Cisco Certified Network Associate and it is design to provide knowledge and skills regarding network administration. The Cisco CCNA certification provides understanding about basic internetworking, OSI model, knowledge about Ethernet Networking and Data Encapsulation, Introduction to TCP/IP and Easy Subnetting. Furthermore, it provides understanding about Variable Length Subnet Masks (VLSMs), Summarization, and Troubleshooting TCP/IP, Cisco's Internetworking Operating System (IOS) and Cisco Internetwork management. In addition to that this certification provides understanding about IP routing, Enhanced IGRP (EIGRP) and Open Shortest Path First (OSPF), Virtual LANs (VLANs), Security, Network Address Translation (NAT) and Wide Area Network (WAN). All these technical networking aspects play crucial role in network management. To acquire CCNA Routing and Switching certification, IT professionals have to go through Cisco CCNA 640-802 exam which is compiled to examine candidate’s learning and understanding in the context of CCNA Routing and Switching course content. So to preparation is a major concern for candidates, though there are several books available on networking but candidates look out for CCNA 640-802 exam dumps. The dumps are based on practice exam questions which allow people to evaluate their preparation before taking real exam. There are various websites that are offering CCNA training material but authenticity is a major concern that’s why I always recommend people to visit certshelp.com as they are known for providing highly reliable and up to date certification training material. So if you are planning to take CCNA Routing and Switching certification than you should look for appropriate training material.
