As we all know, CCNA is an international authority in the field of Internet. CCNA certified professionals have the ability to install, configure, and run medium-sized routing and switching networks, as well as troubleshooting capabilities. Can establish connection with remote site through Wan, eliminate basic security threats, understand the requirements of wireless network access. Those who want to pass CCNA certification can come to waitang.com to watch this Cisco CCNA training tutorial.

CCNA certification is the most elementary certification in the whole Cisco certification system, and it is also a necessary condition to obtain CCNP certification, CCDP certification and CCSP certification (CCIP certification and CCIE certification are not mandatory). CCNA certification is the entry certification of Cisco after-sales engineer certification system, through which you can prove that you have mastered the basic knowledge of network, It can install, configure and operate Cisco router, switch, LAN and WAN. CCNA certification means that the certified personnel have the basic technology and relevant knowledge of networking for the small office / court office (SoHo) market. CCNA certified professionals can install, configure and run LAN, Wan and dial-up access services in small networks (100 or less nodes). The protocols they can use include (but are not limited to) IP, IGRP, OSPF, EIGRP, IPX, serial, apple, talk, frame relay, IPRIP、VLAN RIP、Ethernet、Access Lists。

CCNA covers three aspects: 1. LAN: basic knowledge of network interconnection and network reference model, introduction of Cisco router and switch, principle and configuration of static and dynamic routing protocols (including rip, EIGRP and OSPF), implementation of VLAN and inter VLAN routing, use of CDP, VTP and STP protocols, wireless network interconnection and IPv6, etc. 2. Wan part: Wan access technology, the use of PPP and frame relay, DHCP and NAT, etc. 3. Network security part: introduction of network security, use of access control list and Realization of secure remote office. The value of CCNA certification. After the training of network system engineer certification, it is easy to enter a well-known enterprise to be a system engineer. As a job background, CCNA certification not only reduces the threshold of looking for a job, but also increases the job opportunities, and the real salary has been adjusted satisfactorily. At the same time, through the professional skills training before the examination and certification, we can have a more thorough understanding of Cisco's new technology, and have the ability to use and maintain Cisco network infrastructure. CCNA certification capabilities include: 1. Installing and / or configuring a network; 2. Filtering by using access directory; 3. Optimizing Wan by reducing bandwidth and WAN cost with features such as BOD and DDR. 4. Dial through integrationConnecting and traditional remote LAN to LAN access as well as supporting new applications such as Internet e-commerce and multimedia require the highest level of performance to provide remote access.

The validity period of CCNA certificate is three years. If you want to continue to be valid, you need to take the recertification examination before expiration. If you get a higher level of Cisco certification within three years, the validity period of CCNA certification will be automatically updated. For the re certification examination of CCNA (which can complete one NP subject), you must take the 642-825 examination before the expiration of the validity period, or take the examination of any CCNP, CCIP, CCSP, or take the examination of any prefix 642-xxx in Cisco qualified specialty. Or take some subjects of 646-xxx.
