The qualification of a system engineer is to have a high level of professional skills, be able to analyze business needs, and use various system platforms and

Step 1: Never be new again through the MCSE network

As the first step on the road to certification exams, it is first recommended to study and obtain MCSE (Microsoft Certified System Engineer) for Microsoft Win2000. With the MCSE certificate, it means that you have been able to design, implement, maintain and support information systems and use Microsoft Windows Server network operating system and BackOffice home integrated server products in various environments.

If you have more than one year of rich Win2000 management, application, and practical experience, you can usually pass the exam by focusing on 3 to 6 months of review. Although Microsoft's exam fee increased in 2002 and there are a lot of exam subjects, most of the subjects involved are easy to find in the experimental environment, so it is recommended to take this certification first.

Step 2: Win CCNA and start a full network engagement

Preparation for Cisco's CCNA (Cisco Certified Network Support Engineer) certification exam is expected to take 6-12 months. Although the exam content is only one course, it has some depth than Microsoft's courses, and it is not easy to find an experimental environment. It is generally recommended to use a software that simulates a router to perform a simulation test on a computer first. If you have a chance at work, you can get in touch with the specific operations of Cisco routers. I'm really not sure. You can take part in training in a better laboratory environment, read more English materials, and exchange more in relevant forums, which will help you prepare for the certification exam.

Step 3: Get your hands on the CNA / CNE management network

With two certifications in hand, if the work environment is not suitable for continued learning, you can find a unit closely related to the above skills to work. In specific work, practice and enrich your own experience, and lay the foundation for obtaining CCNP. But if you want to learn more about the network, the next step is to get Novell's network certification.

Although the certification of Novell in China is not very hot, and its product share in the country is not much, Novell's courses are based on multiple platforms, the teaching materials are quite refined, and the lecturers have specially prepared lecturers. The course setting is gradual, logical and rigorous, and it is very scientific. It can integrate the knowledge points you have learned in MCSE and CCNA, and broaden and enrich your technical horizons. Its huge certification system is widely recognized around the world.

With MCSE and CCNA experience, it is not difficult for you to obtain Novell's CNA (Novell Certified Network Administrator) and CNE (Novell Certified Network Engineer). Because most of the knowledge points have been involved before, and there are some subjects that are exempt from the exam, it is estimated that 6 to 10 months will be enough. If you are interested, you can also consider AMP's comprehensive wiring and APC's UPS study or certification exams, which will complement your network and surrounding knowledge.

Step 4: Get CCNP as a Senior Internet Master

At this time, Microsoft's MCSE exam may have been upgraded. If you like, you can use 3 to 6 months to upgrade this exam. At the same time, it is better to win MCSD (Microsoft Certified Development Expert) or MCDBA (Microsoft Certified Database Administrator) if you need to work. If your working environment is satisfactory and you don't plan to change jobs in a short time, you can also ignore this upgrade exam. The next thing to consider is Cisco's CCNP (Cisco Certified Senior Network Support Engineer) exam. The preparation time is 12 to 24 months, and should be supported by practical work experience. CCNP needs to pass more exam subjects, and the difficulty has increased. You need to study carefully and experiment carefully. Although we do not recommend the examination method of back examination questions, it is helpful to read more examination questions before the examination. If you urgently need to take this certificate to choose a more challenging position, you may wish to perform each experiment specifically to enrich and consolidate your knowledge and skills after obtaining the certificate and having a new working environment. Of course, if you do not have any CCNA work experience, even if you rely on back-testing questions, find a person to take the CCNP certificate, and so on, you will not be of much use to you. Because you can't do the job of CCNP at all.

Step 5: Do nt worry about sprinting the future of CCIE

Next you need to sprint is the highest certification in the network industry, Cisco CCIE (Cisco Certified Internet Specialist).

Looking back, you will find that 3 to 5 years have passed. The sweetness and bitterness of the certification is worth remembering, but the improvement of your personal skills will bring you more of the fun in the learning process. Because the certification exam content involves AS / 400, Unix, Windows NT and other aspects. It is of great help to the synthesis and balance of knowledge. As the working environment changes, I believe that Sun's operating system will also have a lot of exposure. With the increasing familiarity with the above systems, if time and energy permit, you can also consider Sun's CSA and CNA certification. If you have the time and energy, and win the Unix and IBM AS / 400 certifications, it will help your job.
