1. Are you preparing for the exam or what kind of network engineers are you training? If it is a national certification, there is a national certification network engineer exam. If it's from cisco certified, it's CCNA CCNP CCIE. If it is Huawei certification, it is HCNE HCSE HCIE Huawei certification and cisco certified network technology certification introduced by the manufacturer. There are some similarities between them. For example, it is divided into three levels, all of which are aimed at network technology. However, Huawei emphasizes that technology can be divided into three grades according to different occasions. For example, those who have reached Huawei Primary Certification (HCNE) should be able to complete the network design, implementation and maintenance tasks of small and medium-sized enterprises, those who have passed Huawei Intermediate Certification (HCSE) can complete the network design, implementation and maintenance tasks of large and medium-sized enterprises, and those who have passed advanced Certification (HCIE) can complete the network design, implementation and maintenance tasks of industrial and telecommunications enterprises. It can be seen that the division of Huawei's certification level emphasizes the occasion of technology application, or what kind of work you can accomplish with this certification. 2.Novell Novell authorizes companies all over the world to hire technicians with CNA qualifications to provide technical support for users of NetWare and GroupWise. CNA can provide support for users in various working environments, including professional companies, small business working groups, various departments and enterprise information service departments (IS). Novell authorizes network engineer (CNE) to prove your technical ability and expand your career by obtaining the highest certificate in IT industry-CNE certificate. As CNE, I can help solve internal network management problems and advanced technical problems. Your task is to plan, install, configure, find faults and provide upgrade services for the network. Novell authorized senior engineer (CNE master) CNE master is the highest level certification in IT industry at present. As a CNE master, you should have the skills to provide solutions to complex network problems distributed on different platforms. Master CNE training can help you acquire more knowledge and skills. With these knowledge and skills, you can provide solutions for the interconnection, integration and management of complex networks. A CNE master should provide customers with rigorous integrated solutions and flexible network management solutions. Enterprises rely on people with master's degree in CNE to establish safe and manageable intranet/Internet sites and transform their network structure into a network that can handle the needs of today's Internet network. You can choose multiple CNE master majors according to your interests, customer base and business needs. Multiple majors allow you to serve customers who use different technologies and network products and play the role of a technology integration expert. Network engineer belongs to the intermediate qualification of software examination, and takes computer and network knowledge in the morning. Examination time 150 minutes, written test and multiple-choice questions. In the afternoon, there will be an exam on network system design and management. The exam time is 150 minutes, written test and question and answer. There are no qualifications, academic qualifications and other conditions for applying for the software exam. As long as you reach the corresponding level, you can apply for any level and major. So do network engineers.
