I am a trainer, I have done CCNA and network three-level training, and my work place is in Beijing. Give you a professional and specific introduction. Cisco Series Certification This series includes three levels: CCNA, CCNP, CCNP and CCIE. Needless to say, this is a costly and time-consuming exam. Moreover, due to the proliferation of question banks, the gold content of certificates is reduced, which I do not recommend. After all, the cost is not small. It takes about 65,438+0 to pass the CCNA exam, 800 yuan RMB (including training fees). Huawei series certification Huawei's network product line ranks second in the world. Huawei's network product certification training system is divided into three levels: Huawei Certified Network Engineer (HCNE), Huawei Certified Senior Network Engineer (HCSE) and Huawei Certified Network Expert (HCIE). At present, Huawei has opened two exams, HCNE and HCSE. Huawei Certified Network Engineer (HCNE) mainly focuses on the maintenance and configuration of small and medium-sized networks. It consists of a course "Network Configuration and Maintenance of Small and Medium-sized Enterprises", including network foundation, interfaces and cables, lan switches router foundation, TCP/IP/IPX protocol, WAN protocol, routing protocol, DDR/ISDN, access list, simple network troubleshooting and other related knowledge points. Pass the corresponding certification examination, and obtain the "Huawei Certified Network Engineer" (HCNE) certificate issued by Huawei. "Huawei Certified Senior Network Engineer" (HCSE) mainly focuses on the configuration, maintenance and scheme design of medium and large campus networks. It consists of three courses: Huawei routing network construction, Huawei local switching network construction and Huawei campus network scheme design. The above three courses cover the theoretical and practical knowledge of equipment configuration and maintenance required for the all-round deployment of campus network, such as routing, switching, access, VPN, VOIP and QOS. "Huawei Certified Network Engineer" can obtain the certificate of "Huawei Certified Senior Network Engineer" issued by Huawei after passing all the examinations corresponding to the three courses. The HCNE test time is 60 minutes, the number of questions is 50, and the price is 60 dollars. The HCSE exam lasts 60 minutes, the number of questions is 50, and the price is 60 dollars. There is no uniform time for such exams. You can take the exam immediately after registration. It can be said that the time is almost up to you. After registering in the VUE or Prometric Examination Center, you can take the computer examination at the location authorized by Huawei. The exam is drawn from the question bank. I can give two locations in Beijing: Beijing Century Descendants Training Center, contact Xu Yanmei, telephone number 0/kloc-0-82884018, and address 20/F, North Ideal Building, Huangzhuang Road East, Haidian District, Beijing. Beijing Zhong Da Jinqiao Technology Development Co., Ltd., contact Chang Bin, telephone number 0 10-67395366, address Zhong Da Jinqiao Company, Zhongnan Apartment, Beijing University of Technology. (The mobile phone seems to have changed. If necessary, let me ask for you. ) Contact them for Huawei training and help you sign up for the exam. Computer software professional technical qualification and grade examination is a national unified examination jointly organized by the Ministry of Information Industry and the Ministry of Personnel. Examination level and name: The examination in the second half of the year is divided into three levels: beginner, intermediate and advanced, among which the beginners are programmers, network administrators, e-commerce technicians and information processing technicians; The intermediate level is software designer, network engineer, e-commerce designer, embedded system designer and information system supervisor; Project management division, a senior information system, and a system analyst have high gold content. I recommend you to take the exam, and the price is not expensive. In our country, exams are held twice a year. The cost is about 70 yuan, and the examination time is 10 and may 165438+ every year. Adopt the mechanism of online registration and payment. Give you a link. You can look at it in detail. There are also test sites outside Beijing. /ksxx/zhuangyzg/jsjrj/jsjrj _ ksjj.asp Novell Company is the largest network software company in the world, headquartered in Utah, USA. There are three specific types: Novell Certified Network Administrator (CNA), Novell Certified Network Engineer (CNE) CNE) Novell Certified Senior Network Engineer (MasterCNE). The CNE exam is relatively unpopular, with high gold content, but expensive. Let me introduce it to you here. If you want to know more, send me a message.
