Introduction of CCNA certification training
CCNA certification (CCNA- Cisco Network Installation and Support Certification Assistant) is the most elementary certification in the whole cisco certified system, and it is also a necessary condition for obtaining CCNP certification, CCDP certification and CCSP certification (CCIP certification and CCIE certification are not mandatory), and many qualified Cisco professionals also require candidates to obtain CCNA certification first.
First, CCNA certification training
CCNA certification belongs to the entry certification of Cisco after-sales engineer certification system. Through CCNA, you can prove that you have mastered the basic knowledge of network and can initially install, configure and operate Cisco routers, switches and simple local area networks and wide area networks. CCNA certification means that the certified personnel have the basic technology and related knowledge of the networked small office/court office (SOHO) market. Professionals certified by CCNA can install, configure and operate LAN, WAN and dial-up access services in small networks (nodes below 100 or 100). The protocols they can use include (but are not limited to) IP, IGRP, IPX, serial, Apple, Talk, frame, relay, IP RIP, VLAN RIP, Ethernet and access list.
Second, training skills.
Routing LAN and WAN with simple installation, configuration and operation, and defining the contents of "simple" network, such as IP, IGRP, IPX, serial, Apple, Talk, Frame Relay, IP RIP, IPX RIP, VLAN, Ethernet and access list.
Third, CCNA can provide solutions based on training and practical experience:
1. Install and/or configure the network;
2. Obtain the directory by using;
3. Functions such as on-demand bandwidth (BOD) and on-demand dial-up routing (DDR) reduce bandwidth, reduce the cost of WAN and optimize WAN.
4. Provide remote access through integrated dial-up connection, traditional remote LAN-to-LAN access and the highest performance level required to support new applications such as Internet, e-commerce and multimedia.
4. Prerequisites for obtaining CCNA certification
Candidates can apply for CCNA without any certificate, and there is no hard and fast rule on the age, education and foreign language level of candidates.
Verb (abbreviation of verb) CCNA certification exam
There are two ways to take the exam now: 1, 640-801CNA; 2. Take 640-82 1 intro and 640-8 1 1 ICND respectively.
Six, the validity of CCNA certification
CCNA certificate is valid for three years. After three years, you need to take the recertification exam. If you get a higher level of cisco certified within two years, the validity period of CCNA certification will be automatically updated.
Seven. CCNA recertification examination
After the expiration of the validity period, you must take the exam of 640-8 1 1CND, or take any exam of CCNP, CCIP and CCSP, or take any exam of Cisco qualified college with the prefix of 642-XXX.
CCNA training objectives
After completing this course, students will achieve the following goals:

According to the given requirements, realize the configuration of the access layer switch;
Use command line to realize VLAN, VTP, IEEE 802. 1Q and ISL configuration;
Describe the functions and operations of static and dynamic routing protocols (RIP, OSPF, IGRP, EIGRP);
Use SHOW and DEBVG commands to determine the exception of routing protocol;
Ability to configure standard and extended access lists;
Configure serial interfaces (PPP, HDLC) using the command line interface.
