Network operation and maintenance engineer belongs to a branch of network engineer
The network engineer divides the pre-sale and after-sale according to the sales time.According to the engineering steps, it is divided into design, construction, operation and maintenance. Operation and maintenance is the latter two. The main responsibilities are maintenance, upgrading and solving problems when problems occur. As for pre-sale, it is generally based on user needs to give solutions, and then design and construction.
There are other branches of network engineers, such as network security engineers. What you call CISSP is information system security authentication. Generally speaking, it is broad and shallow, that is, all security directions are involved, but the required knowledge points are very shallow. CCIE security direction is deeply involved in the field of communication and network security in CISSP.
In addition, there are network storage engineers, who have more contacts with databases. If they are certified, Oracle‘s OCP and OCM systems are related to this.
When I have worked for many years, I will take charge of the management post and lead my own team. This is the time for you to talk about PMP, which belongs to the professional qualification certification of project management.
CCIE R& S direction is now renamed enterprise. If you go through data communication or operation and maintenance, it‘s the right one.As for other directions, if you need to work or have the spare time to learn, you can‘t recommend it if you don‘t have it. Because many technologies are very deep, you can‘t use it if you don‘t work. For the safety direction only, CISSP is slightly better than CCIE security.
As for simple operation and maintenance engineers, in addition to network knowledge, they have higher requirements for programming languages such as shell, python, data structure and Linux.
First, you have to set a single goal. It‘s the best time for university to learn something, but we must come one by one, that is, get the first one and then think about the second one. We must avoid too many goals, which is not only difficult but also stressful.
Second, if you really want to learn, you need to know what you want. In the future, if you want to engage in the operation and maintenance of data communication, take CCIE enterprise as the original R & amp; S as the goal, study technology well,Rip, EIGRP, OSPF, redistribution, BGP, multicast, IPv6, MPLS VPN, VLAN, STP, these are not only lab test points, but also things you need to master. Certificate and ability complement each other. Let‘s learn from them.
Finally, for college students, I give my suggestions.
1. It is suggested that you take the postgraduate entrance examination and choose the graduate students of our school, so that the scope of professional courses and interview will become your advantage, reducing the difficulty of the whole process.
2. Find a company that you want to go to, such as Huawei, Alibaba, etc. Find the job requirements of the position you want to go to. Generally, in addition to experience, quality and responsibility, it will specially indicate that CCIE has priority in a certain direction or CISP / CISSP has priority. Take these requirements as your own training plan. Go for an internship every winter and summer vacation, and you will enter after graduation. |
